Best YouTube Video Summarizers in 2026: 10 Tools Compared
A YouTube video summarizer is an AI tool that reads a video's transcript and turns it into a short summary of the key points, usually with timestamps so you can jump to the parts worth watching. They're useful for long podcasts, lectures and interviews, and for deciding whether a video deserves an hour of your time.
Quick answer: the best one depends on what you do after the summary.
For fast, clean summaries with clickable timestamps: SnapSummary. It's free to try with no account, and plans start at $5/month.
For a free one-off summary: Gemini. Paste the link and ask.
For summaries inside YouTube on your phone: Eightify.
For a saved, searchable library: Recall, or Glasp if you like highlighting.
For studying (flashcards, mind maps): NoteGPT.
For research across several videos: NotebookLM.
Disclosure: I make SnapSummary, so it's on this list. Unlike most "best of" pages written by a tool's makers, I haven't ranked my own tool #1 for everything. Each tool below says who it's for and who it's not for. Prices and limits change often, so figures were checked in November 2026 from each tool's public pricing and feature pages. Confirm on their sites before you pay.

How I compared them
I looked at the things that matter when you actually use a summarizer every week:
- Speed and effort: how many steps from "I have a link" to "I have the key points". Do you need an account, an extension or a prompt?
- Can you check it? Clickable timestamps and transcripts let you verify a claim instead of trusting the AI.
- Formats: overall summary, timestamped notes, custom prompts, other languages.
- Price and free limits: what you get before paying, and what heavy use costs.
- What happens after: is the summary saved, searchable, exportable or turned into study material?
The 10 tools in detail
1. SnapSummary: best for fast, clean summaries with timestamps
Paste a YouTube link (or click the button in the Chrome extension) and you get a structured summary in seconds. Each point has a timestamp you can click to jump to that moment, so you can check anything or watch just the parts that matter. You can choose an overall summary, key timestamps, detailed timestamped notes, the full transcript or your own prompt, in the language you choose, and ask the video follow-up questions in chat. It handles multi-hour podcasts and lectures. On a phone, add it to your home screen, then share videos to it from the YouTube app. More than 3,000 people have signed up, and it has generated over 15,000 summaries.
Who it's for: people who summarize a few videos a week and want the key points quickly, in a format that's easy to read and check.
Who it's not for: anyone who wants a long-term notes library (Recall, Glasp), flashcards and quizzes (NoteGPT), a native mobile app (Eightify, Recall), or summaries of TikTok, podcasts outside YouTube, or uploaded files. The free plan is also smaller than Glasp's.
Price: free to try (5 summaries, no account), then Pro $5/month or Unlimited $10/month.

2. Glasp: best for highlighting and exporting notes
Glasp started as a web highlighter. Its YouTube summaries sit beside the transcript, which you can highlight and export to Notion, Obsidian and other note apps. It supports several AI models and custom prompts.
Who it's for: students and researchers who want to keep highlights from videos and articles in one place.
Who it's not for: people who just want a quick summary. Summaries are secondary to highlighting, and it relies on YouTube captions, so auto-generated captions can lower accuracy.
Price: free plan with daily limits. Pro is about $15/month, cheaper yearly.
3. Eightify: best for key points while you watch
Eightify puts a short "key ideas" summary with timestamps right on the YouTube page, plus an overview of top comments. It's one of the few with proper mobile apps.
Who it's for: people who want to triage videos quickly, especially on a phone.
Who it's not for: anyone who wants to stay on a free plan, since the free tier is very limited. Summaries are short rather than detailed notes.
Price: about $10/month, less if billed yearly.
4. NoteGPT: best for students
NoteGPT goes beyond summaries with mind maps, flashcards, quizzes and presentations, and it can batch-summarize playlists and channels. It also handles PDFs and documents.
Who it's for: students turning lectures into revision material.
Who it's not for: people who just want fast summaries. It does a lot at once, and the quota system can be confusing.
Price: small free quota. Pro is about $10/month ($9 billed yearly).
5. Recall: best for a personal knowledge base
Recall saves summaries of videos, Shorts, articles and podcasts into a connected, searchable library, and you can chat across everything you've saved. It can transcribe videos without captions and has mobile apps.
Who it's for: people who'll come back to what they summarized months later.
Who it's not for: occasional users who just want a quick summary and won't build a library. The free plan is capped at 10 AI summaries a month.
Price: free (10 summaries a month), or Plus $12/month ($10 billed yearly).
6. HARPA AI: best if you want a general AI browser assistant
HARPA is an all-purpose AI assistant for Chrome. It summarizes YouTube videos beside the player and also automates web tasks with hundreds of built-in commands.
Who it's for: power users who want one AI tool for everything in the browser.
Who it's not for: beginners who only want video summaries. There's a real learning curve, and usage limits can run out quickly.
Price: limited free tier, paid from about $12/month.
7. Gemini: best free option for one-off summaries
Google's Gemini can take a YouTube link directly and summarize it, and you can ask follow-up questions. For occasional use it's hard to beat on price.
Who it's for: anyone who needs a summary now and then and doesn't want another tool.
Who it's not for: regular use. There's no consistent format, no reliable list of clickable timestamps, and you have to write a good prompt each time.
Price: free, with paid Google AI plans for heavier use.
8. NotebookLM: best for research across sources
Add YouTube videos (public, with captions) as sources and NotebookLM answers questions grounded in them, with citations, alongside PDFs, Docs and websites.
Who it's for: comparing several videos, or combining videos with documents for a project.
Who it's not for: summarizing a single video quickly. It's slower to set up, and notes stay inside each notebook.
Price: free, with paid plans for higher limits.
9. YouTube's Ask button: best for staying inside YouTube
YouTube has been adding Gemini-powered "Ask" features under some videos, so you can ask what a video covers without leaving the page.
Who it's for: quick questions about the video you're already watching.
Who it's not for: anyone who needs it to work every time. Availability depends on the video, your region and your account, and nothing is saved.
Price: included where available.
10. ChatGPT and Claude: best for custom formats
General AI assistants can't watch YouTube videos, but if you paste in the transcript they produce strong, flexible summaries in whatever format you ask for, such as action items, study notes or a critique.
Who it's for: people who already pay for one and want full control over the output.
Who it's not for: anyone who wants speed. You have to fetch the transcript, paste it and prompt each time. Our how-to guide has a prompt you can copy.
Price: free plans with limits. Paid plans are about $20/month.
How to choose
- You summarize a few videos a week and want it quick: SnapSummary or Eightify.

It depends on what you do after the summary. For fast, clean summaries with clickable timestamps, SnapSummary. For a free one-off summary, Gemini. For mobile, Eightify. For a saved library, Recall or Glasp. For studying, NoteGPT.
What is the best free YouTube summarizer?
For occasional summaries, Gemini is free and takes a YouTube link directly. For a dedicated tool with clickable timestamps, SnapSummary lets you try 5 summaries with no account, and Glasp's free plan includes a few a day.
Is there a YouTube summarizer that doesn't need an account?
Yes. SnapSummary lets you summarize 5 videos without signing up. Most other tools ask you to create an account or install an extension first.
Can ChatGPT summarize a YouTube video?
Not reliably from the link alone. ChatGPT can't watch YouTube videos, so copy the transcript (YouTube's "Show transcript" button under the description) and paste it in with a prompt. Our how-to guide has prompts you can copy.
Can I summarize YouTube videos on my phone?
Yes. Eightify and Recall have mobile apps. SnapSummary works in your phone's browser: add it to your home screen, then share a video to it from the YouTube app. Gemini also has a mobile app.
Do YouTube summarizers work on videos without captions?
Most, including SnapSummary, Glasp, Eightify and NoteGPT, work from captions, which most videos have. Videos with no captions at all may fail. Recall and some paid tools can transcribe the audio instead.
Are AI YouTube summaries accurate?
Usually accurate on the main points when the video has good captions, but they can get details wrong. Use a tool with clickable timestamps so you can check anything important against the original.
