Glasp for YouTube Summaries: Where It Wins and Where It Doesn't

Glasp wins when you want a genuinely free YouTube summarizer with your own choice of AI model, ChatGPT, Claude, Gemini or Mistral, plus highlighting that works on articles and PDFs across most browsers. PeekaTube wins on speed and finished output: one click on the YouTube page, a summary in about 2.6 seconds that also reads the top comments. Glasp Pro runs $15/month; PeekaTube Pro is $5.99/month (as of July 2026).

Glasp is one of the most established names in the space, built around a social highlighting community rather than summaries alone. Its YouTube extension is a genuinely useful, genuinely free tool. This is an honest look at where it leads and where a focused tool like PeekaTube pulls ahead.

How does Glasp actually summarize a YouTube video?

Glasp's extension grabs the transcript and hands it to an AI model of your choice, rather than generating a finished summary on its own servers. After you install the browser extension, you open a video, click the YouTube Summary icon, and it produces a summary along with a side panel transcript that has clickable timestamps. You can also paste a URL at glasp.co/youtube-summary without installing anything. The strength here is transparency: you see the transcript and pick how it gets processed. The cost is a few more moving parts than a single native button.

Is Glasp actually free for YouTube summaries?

Mostly yes, with an honest asterisk on the word "unlimited." Glasp's free plan gives you 3 basic summaries per day with no account and no credit card, which is generous for casual use. What is not free is the "advanced" experience, the summary rendered directly on the video page as you watch, which is a paid feature. So the free tier is real and useful, but the everyday, watch-along version most people picture is behind Pro. If you summarize a video or two a day, free Glasp covers you comfortably.

Which AI models does Glasp let you choose, and why does it matter?

Model choice is Glasp's signature advantage, and no single-pipeline tool matches it. You can route a summary through ChatGPT, Anthropic Claude, Google Gemini, or Mistral, and you can customize the prompt and summary length. If you already trust one model's tone, or you want to compare how Claude and Gemini handle the same lecture, Glasp is built for that. PeekaTube deliberately does not offer this. It runs one tuned pipeline so you never think about models, which is the right call for people who just want a clean answer, and the wrong call for people who want to tinker. If model flexibility is the whole point for you, read is ChatGPT enough to summarize YouTube for where raw model access helps and where it falls short.

Does Glasp analyze the YouTube comments?

No, and this is the clearest functional gap between the two tools. Glasp summarizes the transcript, which is what the creator said. It does not fold in what the audience thought. PeekaTube pulls the transcript plus the top comments, so a summary can flag corrections, disputed claims, timestamps viewers found useful, and the general reception. For tutorials, product reviews, and anything where the comment section is half the value, that context is the difference between a recap and a verdict. If Glasp is enough for you here, that genuinely means comments do not matter for what you watch.

What does Glasp Pro cost, and what does it add?

Glasp Pro is $15/month or $150/year ($12.50/month) as of July 2026, after a price update that took effect May 1, 2026. Pro unlocks the advanced on-page summaries (1,000 per month), unlimited basic summaries, larger PDF and audio transcription limits, private highlights, and daily Notion sync. There is also a higher Unlimited tier at $36/month or $360/year. This is a fuller learning suite than a YouTube summarizer alone. If you only want video summaries, you are paying for a lot of adjacent tooling. PeekaTube Pro is $5.99/month or $29.99/year and buys exactly one thing done well: unlimited YouTube summaries.

Where does PeekaTube fall short?

Plenty, if Glasp's breadth is what you need. PeekaTube is Chrome only, so Safari, Firefox, and mobile users are out, while Glasp spans six browsers. PeekaTube is YouTube only, so it will not touch the articles and PDFs Glasp handles, and it has no highlighting community. PeekaTube gives you no model choice, which is a real limitation if you specifically want Claude or Gemini. And beyond the 3 free guest summaries, heavy use requires a subscription, whereas Glasp's free daily allowance can carry a light user indefinitely. Those are the honest trade-offs of a narrow, fast tool.

When Glasp is the better choice

Pick Glasp if you want to choose your AI model, if you summarize articles and PDFs as often as videos, or if you live in Safari, Firefox, or another non-Chrome browser. Pick it if you value the social highlighting community, or if 3 summaries a day for free is all you need and you would rather not pay anything. Its free tier is one of the most generous in the category, and that alone makes it worth trying before you decide.
