The 9 Best YouTube Summarizers in 2027 (Compared on Where the Summary Lives)

Nine YouTube summarizers compared for 2027 on where the summary lives, transcripts, chat and price — Marqly, Glasp, NoteGPT, Recall, Readwise Reader and more.

The best YouTube summarizer for most people in 2027 is Marqly, because the summary lives where you watch — an AI card on the watch page with a streaming TL;DR, key sections, a playback-synced transcript and a chat tab that answers questions from the video — and because saving the video attaches its transcript to a library you can search by meaning. Glasp is the best free option on the watch page. NoteGPT is the pick for students who want mind maps and flashcards. Recall handles videos measured in hours. Readwise Reader, Matter and LINER are verified additions to this edition, and ChatGPT remains the free manual route with a real ceiling.

The difference between these tools is not summary quality — everyone calls a capable model now, and the text is fine everywhere. It is where the summary lives (on the watch page, or in a separate app you have to visit), whether you get the transcript, whether you can chat with the video, and what survives afterwards.

How this list was compiled. We compare watch-page integration, transcript handling, chat, free-tier allowances, platform reach and pricing using dated competitor fact sheets and linked official sources, published in how we test. Marqly publishes this article and is one of the nine products discussed, so weigh our own section accordingly — Glasp’s free allowance is more generous per day than ours is per month, and we say so below.

What changed in YouTube summarizers since our 2026 edition

  • We removed a test we should never have published. Our 2026 edition claimed we “ran each tool against the same three videos — a 12-minute tutorial, a 90-minute podcast, and a 20-minute lecture.” We did not run that test. It was written, not measured, and it is gone. The only measured asset we own is the import-fidelity study, and this article now cites no numbers we have not measured. Everything below comes from dated fact sheets and vendor documentation instead.
  • Marqly’s free allowance was not stated. Our 2026 table said the free tier was “Yes” and the closing line said “the summary tab works without a card,” which was true but incomplete. The Summary tab carries a three-per-month allowance on the free plan. The Chat tab is Pro.
  • Three verified tools were missing entirely. Readwise Reader gives YouTube videos synced transcripts you can read, highlight and query. Matter transcribes YouTube videos and podcasts with time-synced text you can highlight, and has the best text-to-speech in the category. LINER clips YouTube moments into a private library alongside citation-backed AI search. All three have dated fact sheets; none appeared in 2026.
  • A Glasp quota figure we printed is unverifiable. We wrote that Glasp Pro “raises that to 1,000 advanced summaries a month.” Our fact sheet records no paid quota number, so that figure is removed rather than repeated.
  • Glasp’s free allowance was under-credited. Three YouTube summaries a day is materially more generous than Marqly’s three a month for casual use, and Glasp makes the most widely used YouTube summary extension in the category. It moves from fifth to second.
  • Glasp’s pricing context changed. Prices rose about 20–25% in May 2026, subscriptions are explicitly non-refundable, and there is a student discount on Pro yearly with an academic email. None of that was in our 2026 entry.
  • Eightify drops from fourth to seventh, because the tightest free allowance here (three videos a week, 30-minute ceiling) combined with no chat, no library and no transcript workflow is a thinner answer than we credited.

The four things that actually separate these tools

  1. Where the summary lives. On the watch page, at zero friction, or in a separate workspace you have to visit while the video plays. This decides whether you actually use it.
  2. The transcript. A summary is a receipt; the transcript is the asset. Playback-synced, copyable and — critically — retained with the save.
  3. Chat. Asking the video a question beats reading a paragraph about it, especially for lectures and long interviews.
  4. What survives. Whether the summary and transcript land somewhere searchable, or evaporate when you close the tab. Three of the nine tools below keep nothing.

A note on what we could and could not verify

Six of the nine tools here have dated fact sheets in our data layer, and every price and plan limit for those was re-checked in October 2026: Marqly, Glasp, Readwise Reader, Matter, LINER, plus the shutdown records for tools that no longer exist.

Three do not: NoteGPT, Recall and Eightify. They remain in this list because they are among the most-searched dedicated summarizers and omitting them would make the article less useful, but their prices and quotas carry forward from our August 2026 edition and were not re-verified for this one. We publish them because we published them before and removing them silently would be worse; we label them so you can weigh them correctly. Confirm against each vendor’s pricing page before you subscribe, and treat any figure below for those three as indicative rather than current.

1. Marqly — best overall, because the summary lives on the watch page

Marqly’s extension adds a YouTube AI card to every watch page with three tabs: Summary (a streaming TL;DR plus key sections, and it pulls out books mentioned in the video), Chat (questions answered from the video’s transcript, on Pro), and Transcript (synced to playback, one-click copy). There is also a bookmark button in YouTube’s own action row that saves the video to your library with its transcript attached.

That last part is the structural difference, and it is why this ranks first. Every other tool here summarises and forgets. Marqly summarises and then makes the video part of a searchable library: on Pro, semantic search finds “that video about sourdough starters” from what was said in it, not just its title, because the index covers titles, content, highlights and video transcripts. The full flow is in how to summarize YouTube videos with AI and how to chat with a YouTube video.

Be precise about the free tier, because our 2026 edition was not. The Summary tab carries a three-per-month allowance on free; the Chat tab is Pro, as are AI summaries on saves, auto-tagging and semantic search. The free plan stores up to 100 bookmarks with keyword search across the whole library. The side-panel workspaces are Chrome and Edge only, and there is no public API or self-hosting.

Who it’s best for: people who watch on desktop in Chrome, Edge, Firefox or Safari and want the summary at zero friction plus a library that keeps the transcript. Skip it if you summarise more than three videos a month and will not pay, or you want mind maps and flashcards (NoteGPT).

  • Pros: summary, chat and transcript in one card on the watch page; saved videos keep their transcripts, so the library is searchable by what videos say; part of a full AI bookmark manager with six-colour highlighting and boards free on every plan; web, Chrome, Edge, Firefox, Safari, iOS and Android.
  • Cons: three summaries a month on free; chat requires Pro; YouTube only — no podcasts or arbitrary video files; no study-artifact generation; side panel is Chrome and Edge only; no public API.
  • Price: free plan with a three-per-month summary allowance, no card required · Pro $72/year (about $6/month billed annually) or $9/month · a standing $49 first-year offer, 31% off your first year against the $72 baseline · verified students $48 first year, 33% off the same baseline.

2. Glasp — best free watch-page summaries

Glasp makes the most widely used YouTube summary extension in the category, and its free allowance is the most generous per day here: three YouTube summaries a day, alongside 30 PDF uploads and 20 PDF chat messages a month, plus unlimited highlighting. Summaries and transcripts appear on the watch page, and your notes flow into a public Glasp profile with a community feed.

Paid plans are where the video features get serious: advanced YouTube summaries, channel tracking, PDF chat, audio transcription, and an AI clone that answers questions from your highlights. Pro is $12.50/month billed yearly ($150/year) or $15/month billed monthly, and the Unlimited tier is $30/month billed yearly ($360/year) — after prices rose about 20–25% in May 2026. Subscriptions are explicitly non-refundable, and Glasp publishes a 40% discount on Pro for students and educators, billed yearly. Platform reach is the broadest in the niche — Chrome, Safari, Edge and Firefox plus iOS and Android apps rebuilt in 2026, including a mobile Safari extension.

Two honest caveats. Free highlights are public by default, and privacy costs Pro. And we printed a paid quota figure for Glasp in 2026 that our fact sheet does not support, so this edition names no advanced-summary allowance — check the pricing page for the current number. There is also no full-text search, no offline mode and no full-page archiving, and Glasp is run by its two co-founders, which is a real longevity consideration for a tool you would build a study habit on.

Who it’s best for: people who summarise a handful of videos a day for free and are comfortable highlighting in public, or who already use Glasp for reading. Skip it if your highlights must stay private without paying, or you want a searchable transcript library — its search is not full-text and not semantic.

  • Pros: three free summaries a day, the most generous daily allowance here; summary and transcript on the watch page; channel tracking and audio transcription on paid; the strongest export pipeline in the niche — Markdown, CSV, HTML, JSON plus Notion, Obsidian and Readwise; broadest platform coverage; student discount on Pro yearly.
  • Cons: free highlights are public by default; prices rose about 20–25% in May 2026 and subscriptions are non-refundable; tight free AI caps beyond summaries; no full-text or semantic search and no offline mode; two-person team; paid quota not published in our fact sheet.
  • Price: free (3 summaries/day) · Pro $12.50/month billed yearly ($150/year) or $15/month billed monthly · Unlimited $30/month billed yearly ($360/year) · 40% off Pro for students and educators.

3. NoteGPT — best for students and study materials

NoteGPT is a learning workspace: paste a YouTube link — it handles other platforms too — and get a summary, transcript, chat, mind maps and flashcards. That artifact generation is its real edge and nothing else in this roundup turns a lecture into study materials as directly. If your output is a revision deck rather than a TL;DR, this is the tool.

The trade-off is friction: everything happens in NoteGPT’s own workspace rather than on YouTube, so you are tab-switching while you watch. The quota system also takes reading. Our 2026 edition recorded a small free monthly allowance, Pro at $9/month for 1,000 basic quotas, and an Unlimited plan at $19.92/month billed annually ($239/year), with heavy users ending up on the annual plan. Those figures were not re-verified for this edition — we maintain no dated fact sheet for NoteGPT — so confirm them on the vendor’s pricing page before subscribing.

Who it’s best for: students who need flashcards and mind maps from lectures and will work in a separate workspace to get them. Skip it if you want zero friction on the watch page, or you want the video to end up in a searchable library alongside everything else you save.

  • Pros: mind maps, flashcards and notes — the best study-output pipeline here; handles more than YouTube, including PDFs and audio; chat with the video content; Pro pricing is reasonable for what it bundles.
  • Cons: lives in a separate workspace, so constant tab-switching; the quota and credit system is confusing; heavy users end up on the annual plan; more tool than you need for a quick TL;DR; no dated fact sheet, so pricing is carried forward and unverified.
  • Price: not re-verified for this edition — see the disclosure above.

4. Recall — best for very long videos and knowledge bases

Recall is the endurance pick. It summarises YouTube videos up to 10 hours when a transcript exists, and around five hours when it has to transcribe the audio itself, supports 60-plus languages, and files every summary into a personal knowledge base that auto-links related concepts. If your input is conference talks, three-hour podcasts or recorded lectures, other tools here simply stop.

The free plan includes unlimited saving and 10 AI summaries a month, and our 2026 edition recorded Plus at $10/month billed annually for unlimited summaries with a $38/month Max tier above it. Those figures were not re-verified for this edition — we maintain no dated fact sheet for Recall — so check the vendor’s pricing page. The jump from Plus to Max is steep if you outgrow the lower tier.

The structural limits are unchanged: summaries live in Recall rather than on the watch page, and it is summary-and-archive rather than Q&A — there is no transcript-grounded chat with the video. The knowledge-base linking between summaries is genuinely clever, but it links summaries, not the videos themselves.

Who it’s best for: people who summarise marathon content and want a linked knowledge base of the results. Skip it if you want to ask the video questions, or you want summaries without leaving YouTube.

  • Pros: handles content up to 10 hours that chokes other tools; 60-plus languages; knowledge-base auto-linking between summaries; a decent free plan with unlimited saving and 10 summaries a month.
  • Cons: summaries live in Recall, not on the watch page; no transcript-grounded chat; the Plus-to-Max jump is steep; no dated fact sheet, so pricing is carried forward and unverified.
  • Price: not re-verified for this edition — see the disclosure above.

5. Readwise Reader — best if you highlight and query what you watch

Readwise Reader is the addition that most changes this list, because it treats a YouTube video as a document. Videos get synced transcripts you can read, highlight and query exactly like an article, and the Ghostreader assistant answers questions against the text. Everything you mark flows into the Readwise loop: highlights resurface on a spaced-repetition schedule and export continuously to Notion, Obsidian, Evernote and Roam, with a documented public API.

If your reason for summarising a video is to retain and reuse it — a lecture series, a research interview, a conference talk you will cite — nothing else here closes that loop. It is also the only tool in this roundup where a YouTube transcript becomes a first-class highlightable document with an export path.

The costs are price and location. Reader ships only with the Readwise Full plan, and there is no permanent free tier: Readwise offers a 30-day trial, after which a subscription is required. Full is $9.99/month billed annually ($119.88/year) or $12.99/month monthly, while the cheaper Lite plan at $5.59/month billed annually excludes Reader entirely. Verified students and educators get 50% off. And the transcript lives in the Reader app, not on the watch page, so you are reading video rather than watching it.

Who it’s best for: students, researchers and writers who treat video as source material to highlight, cite and review. Skip it if you want free, you want the summary while the video plays, or you only need a quick gist.

  • Pros: synced, highlightable YouTube transcripts treated as documents; query the transcript via Ghostreader; spaced-repetition review that fights forgetting; continuous export to Notion, Obsidian, Evernote and Roam plus a documented API; 50% student and educator discount.
  • Cons: no permanent free tier; Reader requires the Full plan at $119.88/year; transcripts live in the app rather than on the watch page; keyword rather than semantic search; manual tagging; Reader’s extensions are Chrome and Firefox only.
  • Price: no free tier · Full $9.99/month billed annually ($119.88/year) or $12.99/month monthly · Lite $5.59/month billed annually, without Reader.

6. Matter — best for listening to what a video said

Matter is the audio-first answer and a verified addition to this edition. It transcribes YouTube videos and podcasts with time-synced text you can highlight, then reads any of it back with the best text-to-speech in the category — human-like voices with word-by-word tracking, so you can switch between reading and listening mid-transcript. For a two-hour podcast you would rather walk than watch, nothing else here competes.

The free tier is real: unlimited library, excellent parsing, unlimited tags. Premium adds HD voices, unlimited highlighting and notes, offline full-text search, and highlight syncing out to Notion, Obsidian and Readwise. Check where you buy: the same annual plan is $8/month or $60/year on the web versus $7.99/month or $79.99/year through the iOS App Store, $20 more per year for identical features, and a Matter Pro tier at $12.99/month also appears in the App Store.

The limits are structural rather than financial. Matter has no AI summaries, no chat and no automatic tagging — it transcribes and reads beautifully, but it will not answer a question about the video. There is no Android app; Matter covers iPhone, iPad, Mac, the web and a Chrome extension. There is no public API and no public sharing.

Who it’s best for: Apple-ecosystem commuters who want to listen to long video and podcast content and highlight what they hear. Skip it if you use Android, you want to chat with the video, or you want automatic summaries rather than a transcript you read yourself.

  • Pros: transcribes YouTube and podcasts with time-synced text; the best text-to-speech in the category; you can highlight the transcript; solid free tier with an unlimited library; highlights sync to Notion, Obsidian and Readwise; newsletter delivery by Gmail or email address.
  • Cons: no AI summaries, chat or auto-tagging; no Android app; annual Premium costs $79.99 through the App Store versus $60 on the web; no public API or sharing; HD voices, unlimited highlighting and full-text search sit behind Premium.
  • Price: free · Premium $8/month or $60/year on the web · $7.99/month or $79.99/year via the iOS App Store.

7. Eightify — best cheap, instant TL;DR

Eightify is the one-trick tool that does its trick well: click a button on the watch page and get a timestamped summary of key ideas in seconds. It has a Chrome extension plus iOS and Android apps, and unlimited summaries cost $4.95/month or $3.95/month billed annually — the cheapest dedicated paid option here. Free covers three videos a week up to 30 minutes each, which is the tightest allowance in this roundup and runs out inside a single study session.

Those figures carry from our August 2026 edition; we maintain no dated fact sheet for Eightify, so verify them before subscribing.

What it does not do is the reason it ranks seventh rather than fourth. There is no chat, no library, no search and no transcript workflow — you get the gist and move on, and nothing carries forward. Every video is a fresh start, which means you will re-summarise the same videos next year if your need is reference rather than triage. The 30-minute free ceiling also rules out exactly the long lectures and podcasts where a summary is worth the most.

Who it’s best for: people who want the cheapest possible instant TL;DR on short videos and genuinely do not need to keep anything. Skip it if you summarise more than three videos a week, your videos run past 30 minutes, or you want the summary to be findable later.

  • Pros: fast timestamped summaries right on the watch page; the cheapest paid plan in this roundup; iOS and Android apps alongside the Chrome extension; nothing to learn.
  • Cons: the tightest free tier here at three videos a week with a 30-minute cap; no chat, no search and no library; summaries are disposable and nothing carries forward; no dated fact sheet, so pricing is carried forward and unverified.
  • Price: not re-verified for this edition — see the disclosure above.

LINER clips YouTube moments into a private My Space alongside web pages and PDFs, and pairs them with citation-backed AI search that links every claim in an answer to its source. If your workflow is research — gather moments from several videos, then ask questions across them with verifiable citations — that combination is unique in this list. Liner Scholar adds literature-review, citation-recommendation and hypothesis agents for academic work.

Its free tier is better than most roundups credit: unlimited highlighting and unlimited citation-backed AI search, plus ten research-assistant uses a day. What free also means is ads inside AI answers, zero agent credits and one small file upload a day. Paid tiers unlock credits, larger uploads and premium models from OpenAI, Google and Anthropic under one subscription: Pro $17.99/month or $14.99/month billed annually, Max $35.99/month or $29.99/month annual, Team $26.99/seat/month annual. Agent credits do not roll over and Deep Research costs 40 per request.

Two cautions. LINER’s centre of gravity is no longer highlighting or video — the old getliner.com domain returns a 410 pointing to liner.com, and the Safari and Firefox extensions were dropped, leaving web, Chrome, Edge, iOS, Android, Mac and Windows. And the current product advertises no export for saved highlights, with no import tools either, so a My Space you build over years has no documented way out. There is also a card-required trial whose length is not published, alongside documented complaints about trials converting to large annual charges and refused refunds — check your subscription settings the day you sign up.

Who it’s best for: researchers and students who want video moments inside a citation-backed AI search workflow and will pay for agent credits. Skip it if you just want a summary of a video, or if being unable to export your library is disqualifying.

  • Pros: clips YouTube moments into a private library; unlimited highlighting and unlimited AI search on free; line-by-line citations on answers; Liner Scholar’s academic agents; one subscription covers multiple premium models; wide device reach including Mac and Windows apps.
  • Cons: video is a side feature, not the product; no export advertised for saved highlights; free tier shows ads and grants zero agent credits; credits do not roll over; Safari and Firefox extensions dropped; an unpublished-length card-required trial with documented billing complaints.
  • Price: free (unlimited highlighting, ads, no agent credits) · Pro $17.99/month or $14.99/month annual · Max $35.99/month or $29.99/month annual · Team $26.99/seat/month annual.

9. ChatGPT, Claude and Gemini — the free manual method, and its ceiling

The DIY route: get the video’s transcript, paste it into a chat model, and prompt “summarise this, then answer my questions.” It works, it is flexible, and free tiers handle short videos. You get total control over the prompt — any format, any language, any depth — and chat is the whole product, so follow-up questions are natural. If you summarise one video a month and enjoy prompting, you do not need to pay anyone.

The friction is real and compounds. You fetch the transcript yourself every time, which is a separate skill — our guide to getting a YouTube video transcript covers it. Very long videos exceed context limits and need chunking, which breaks cross-referencing between the parts. Timestamps get lost, so a claim in the summary cannot be traced back to the moment in the video. And nothing persists: no library, no search, no history tied to the video. It is a workflow you rebuild from scratch every single time.

The paid tiers — ChatGPT Plus at $20/month and its equivalents — raise context limits but do not change the shape of the problem. We maintain no dated fact sheet for any consumer chat model, so treat that price as indicative.

Who it’s best for: occasional summarisers who like prompting and do not need anything to survive the session. Skip it if you summarise weekly, you watch long content, or you want the result findable in six months.

  • Pros: free, or the subscription you may already pay for; total control over prompt, format, language and depth; follow-up questions are natural; works for any video you can get a transcript for.
  • Cons: manual transcript-fetching every time; long videos need chunking; timestamps are lost; nothing persists; no watch-page integration; a workflow rebuilt from scratch per video.
  • Price: free · paid tiers from about $20/month, not re-verified for this edition.

Free-tier math: what a week of summarizing actually costs

Free tiers sound interchangeable until you price them against your actual volume. Per day or per week:

  • Glasp — three summaries a day. The only free tier here that survives daily use.
  • Marqly — three summaries a month. Enough to evaluate, not enough to live on; the library and transcript retention are the reason to pay.
  • Eightify — three videos a week, each capped at 30 minutes. Gone by Wednesday if you study.
  • Recall — ten summaries a month with unlimited saving. Saving is free; summarising is rationed.
  • LINER — unlimited highlighting and unlimited AI search, with ads in answers and no agent credits.
  • Matter — an unlimited library and transcription; the paywall is HD voices and unlimited highlighting, not the transcript.
  • ChatGPT and friends — effectively unlimited for short videos, at the cost of your time and everything persisting nowhere.

If you summarise one video a day, the honest answer is Glasp on free or a paid plan somewhere. If you summarise three long lectures a month and want to cite them next year, the free tiers are the wrong axis entirely — retention is, which points to Readwise Reader or Marqly.

Which YouTube summarizer should you choose?

  1. You want summaries while you browse YouTube with zero friction, and you want the video to stay findable → Marqly. The card is there when the page loads, and saved videos keep their transcripts.
  2. You want free and you summarise most days → Glasp, accepting that free highlights are public.
  3. You are studying and want flashcards and mind maps → NoteGPT, accepting the separate workspace.
  4. You summarise three-hour podcasts, lectures and conference talks → Recall.
  5. You treat video as source material to highlight, cite and review → Readwise Reader, at $119.88/year.
  6. You would rather listen than watch → Matter, subscribing on the web to avoid the App Store markup.
  7. You want the cheapest instant TL;DR on short videos and keep nothing → Eightify.
  8. You want video moments inside citation-backed research search → LINER, accepting that highlights cannot be exported.
  9. You summarise one video a month and enjoy prompting → ChatGPT, Claude or Gemini.

One filter worth applying to all nine: ask what happens to the summary afterwards. If the answer is “it evaporates,” you will be re-summarising the same videos next year, and the tool you chose was a rental rather than a library.

What actually matters in 2027

Summary quality stopped being the differentiator. Every tool here calls a capable model and produces acceptable prose. The differences are friction, transcript handling and retention — and retention is the one nobody shops for.

The transcript is the asset; the summary is the receipt. A summary you cannot trace back is a rumour about a video. Tools that keep a synced transcript with the save — Marqly, Readwise Reader, Matter — let you verify, quote and search what was actually said. Tools that hand you a paragraph and keep nothing do not. If you will want the video again, buy for the transcript.

Free tiers are rationed on the axis that matters least. Most ration the number of summaries, which is the cheap part. The expensive part — keeping the transcript, searching it by meaning, citing it next year — is what the paid tiers actually charge for. Price your volume first, then decide whether retention is worth more than the allowance.

We removed a fabricated test from this article and replaced it with a disclosure about which vendors we can verify. That is a slower way to write a roundup and a better way to read one. If you want the version of this job that ends in a searchable library rather than a closed tab, Marqly saves the video with its transcript attached and makes it findable by meaning — free plan, no card required, and a three-per-month summary allowance to try it on. See also saving YouTube videos to watch later and the YouTube summarizer overview.


Prices and plan limits for Marqly, Glasp, Readwise Reader, Matter and LINER verified against dated competitor fact sheets in October 2026. NoteGPT, Recall, Eightify and consumer chat models have no fact sheet in our data layer; their figures carry forward from our August 2026 edition and were not re-verified. Changes from the 2026 edition: the fabricated three-video comparison test removed and replaced with a disclosure of what we can and cannot verify; Marqly’s free Summary tab corrected to a three-per-month allowance and its Chat tab scoped to Pro; Readwise Reader, Matter and LINER added as verified entries; Glasp promoted from fifth to second on its three-per-day free allowance, with its May 2026 price rise, non-refundable subscriptions and student discount documented; an unverifiable Glasp paid-quota figure removed; Eightify demoted from fourth to seventh on its free cap and lack of retention; and Marqly’s platform list corrected to include Edge, Firefox, Safari and Android. We’ll update this comparison as the landscape shifts.

Frequently asked questions

What is the best YouTube summarizer in 2027?
Marqly is the best for most people because the summary appears on the YouTube watch page itself — a streaming TL;DR with key sections and books mentioned, plus a playback-synced transcript tab and a chat tab that answers questions from the video. Saving the video attaches its transcript, so it stays searchable by what was said in it. Glasp is the best free option on the watch page, with three summaries a day. NoteGPT is better for study artifacts like mind maps and flashcards, and Recall is better for videos measured in hours.
Is there a free way to summarize YouTube videos?
Yes, several, and the free tiers are the real story here. Marqly's Summary tab works on the free plan with a three-per-month allowance. Glasp gives three summaries a day free. Eightify allows three videos a week up to 30 minutes each. Recall includes ten AI summaries a month with unlimited saving. You can also paste a transcript into ChatGPT, Claude or Gemini free — it works, but you fetch the transcript yourself and long videos need chunking.
Is Marqly's YouTube summary free?
The Summary tab has a three-per-month allowance on the free plan, which is enough to try it and not enough to live on. The Chat tab, which answers questions grounded in the video's transcript, is a Pro feature, as are AI summaries on every save, auto-tagging and semantic search across your library including transcripts. Pro is $72 a year, about $6 a month billed annually, or $9 a month, and there is no trial of any length — the free plan runs until you upgrade.
Can I ask questions about a YouTube video instead of just summarizing it?
Yes, and it is usually more useful than a summary. Marqly's YouTube card has a Chat tab on Pro that answers questions from the video's transcript right on the watch page. Readwise Reader lets you query synced YouTube transcripts through Ghostreader. Glasp's paid plans add an AI clone that answers from your highlights. NoteGPT offers chat in its own workspace, and the manual route is pasting the transcript into ChatGPT and asking there.
What happened to Eightify?
Nothing — it is still alive in 2027, with a Chrome extension plus iOS and Android apps. The free plan covers three videos a week up to 30 minutes each, and unlimited summaries cost $4.95 a month or $3.95 a month billed annually. It remains a solid quick-TL;DR button, but it has no transcript chat, no searchable library and nothing that carries forward between videos. Note that we maintain no dated fact sheet for Eightify, so those figures carry from our August 2026 edition.
Do YouTube summarizers keep the transcript?
Some do, and it matters more than the summary. Marqly's bookmark button saves the video with its transcript attached, so semantic search can find it later by what was said. Readwise Reader gives YouTube videos synced transcripts you can highlight like an article. Matter transcribes YouTube videos and podcasts with time-synced text you can highlight. Eightify and the manual ChatGPT route give you the gist and keep nothing. If you will want the video again in six months, the transcript is the asset and the summary is the receipt.
