Glasp YouTube Summary vs Claras: two ways to summarize a video
Glasp YouTube Summary is a free browser extension that summarizes videos with ChatGPT, Claude, Gemini or Mistral, and it also reads articles and PDFs. Claras is a web app and Chrome extension built around video, with transcripts, chapters and a chat.
Claras vs Glasp, side by side
Glasp's extension is called YouTube Summary with ChatGPT & Claude. Both put a summary and a transcript next to a YouTube video. They differ in where the summary is written, what else they read, and how the limits work.

The main differences, explained
Who writes the summary
Glasp gives you two kinds of summary. The first is sent to an assistant: the extension opens ChatGPT, Claude or Gemini in a new tab with the video's transcript and a prompt, and the summary is written there. The free plan allows 3 of these a day, or 2 without a Glasp account. Glasp's page doesn't say if you need to be signed in to that assistant. The second kind is written beside the video, using the model you choose from ChatGPT, Claude, Gemini or Mistral. These need a free Glasp account, and the free plan includes 3 every 7 days, shared with article and PDF summaries.
Claras writes every summary itself and shows it in Claras. It doesn't need an account with any other AI. If you later want ChatGPT or Claude to work on the video, Send to AI copies the full transcript and opens the assistant you pick.
What each one reads
Glasp is also a highlighter for the web, and its summarizer follows you around the web: YouTube, articles, newsletters and PDFs, with your highlights feeding its chat. Claras reads video and audio only, but more kinds of it: YouTube, Instagram and TikTok links, and your own files. For a YouTube video with no captions, Claras transcribes the audio. Glasp's page doesn't say what happens then, and describes transcripts in the languages YouTube has captions for.
The same job in each: a two-hour podcast on YouTube
Say a podcast you follow posts a two-hour episode, with captions, and you want to know whether to listen.
In Glasp, you open the video and the transcript appears beside it. Click to summarize there, and one of your 3 free summaries for the week is used. Or send it to ChatGPT, Claude or Gemini in a new tab, one of your 3 a day. Glasp's FAQ says the whole transcript is processed, even for a two-hour video, and the summary includes timestamps. Click a key point to jump there. For questions, open Chat beside the player: each question uses one of 20 free credits a month.
In Claras, sign in with a free account, then click Summarize under the video with the extension, or paste the link in the web app. Claras reads the captions, writes an overview, key takeaways and a summary for each section, and builds chapters. The extension marks the chapters on YouTube's progress bar. Ask AI answers from the transcript and usually gives the time as text, which you then find in the player yourself. Questions aren't counted, but the episode uses one of your 3 free videos a month.
What each costs in practice
Glasp's prices are in the table above. Its pricing page also offers a free Glasp Student plan with a university email, and 40% off Pro yearly for students and educators. Claras prices are on the pricing page. Three example months:
- One video a day, summary only. Glasp's free plan covers this if you are happy reading the summary in ChatGPT, Claude or Gemini. Claras's free plan doesn't, and Pro does.
- Ten questions a day about what you watch. Glasp's 20 free chat credits last two days, and Pro includes 500 a month. Claras Pro doesn't count questions, and allows 50 videos a day.
- Articles and PDFs as well as videos. Glasp covers all three. Claras can't summarize an article or a PDF at all.
Where Glasp is stronger
- A free plan for daily use. 3 videos a day sent to ChatGPT, Claude or Gemini, at no cost. Claras's free plan is 3 videos a month.
- More than video. Articles, newsletters and PDFs, plus a highlighter. Claras reads video and audio only.
- Notes that go somewhere. Highlight transcript lines and export to Notion, Obsidian, Roam Research or mem.ai. Claras doesn't connect to note apps.
- Browsers and phones. Chrome, Edge, Firefox and Safari, plus phone apps. Claras is a web app and a Chrome extension.
- Summary controls. You set the length and the number of key points. Claras takes style instructions but not a length.
Where Claras is stronger
- Videos with no captions. Claras transcribes the audio, up to 3 hours on a paid plan.
- Instagram, TikTok and your files. The same transcript, summary and chat, from a link or an upload.
- Many videos at once. Bulk Summaries reads a playlist or search page and gives you one summary, then answers across all of it.
- Chapters. AI chapters jump to their moment and sit on YouTube's progress bar.
- No credits for questions. On a paid plan, ask as much as you like about a video you have open.

Who should choose which
Choose Glasp if
- You want a free summary of a video or two a day and already use ChatGPT, Claude or Gemini.
- You read as much as you watch, and want one tool for articles, PDFs and videos.
- You highlight and keep notes in Notion, Obsidian or Roam.
- You browse in Firefox or Safari, or want summaries on your phone.
For these, Glasp is the better fit, and we would rather say so.
Choose Claras if
- Many of your videos have no captions: talks, lectures filmed in a room, interviews.
- You also learn from Instagram and TikTok, or from your own recordings.
- You want a playlist or a YouTube search page summarized together.
- You ask a lot of questions and don't want to count credits.
- You want the summary and chapters in one place, without a second AI account.
If you are price-sensitive
Start with Glasp's free plan for the summaries, and try Claras's free plan on the videos where Glasp can't help, such as one with no captions or one from TikTok. That tells you quickly if the gap matters for what you watch.
Using both, or moving across
Using both
This works if you split your time between reading and watching. Keep Glasp for articles, PDFs and your highlights, and use Claras for videos, especially ones with no captions and ones from Instagram or TikTok. We found no direct connection between the two, so anything that moves between them moves by hand.
Moving from Glasp to Claras
Export your highlights and notes first, to Notion, Obsidian or a Markdown file, since Claras has nothing to import them into. Claras starts from links and files, so paste the YouTube links you care about and Claras makes new transcripts and summaries. If you relied on Glasp sending summaries to ChatGPT or Claude, Send to AI does a similar job: it copies the whole transcript and opens the assistant, and you paste it in.
Moving from Claras to Glasp
Download the transcripts and summaries you want to keep. Glasp shows the transcript beside any captioned YouTube video, so you won't need those for videos that have captions. For videos with no captions, and for Instagram, TikTok and your own files, keep the Claras transcripts, since Glasp's YouTube page doesn't cover them.
