Glasp YouTube Summarizer Alternative: What to Compare

If you are looking at Glasp for YouTube transcripts and summaries, you have picked a strong tool. Glasp is well built for reading, highlighting, saving, and organizing what you learn, and its YouTube transcript and summary features are genuinely useful. This article is not here to talk you out of it.

Instead, this is a fair comparison for one specific decision: how you want to work through YouTube videos day to day. Glasp is a broad highlighting and knowledge-management product that happens to do YouTube well. Vidskim is narrower on purpose. It is a Chrome extension that keeps the transcript, translation, export, one-click summary, and chat with the current video together on the YouTube page you are already watching.

Both can get you a transcript and a summary. The difference is what you want around that, and where the work happens.

Everything below about Glasp was checked on 2026-07-04 against the live public pages at glasp.co/youtube-transcript and glasp.co/pricing. Where a feature was not visible on those pages, this article says so plainly rather than guessing. Vidskim is independent and is not affiliated with YouTube or with Glasp.

Quick verdict by workflow

• You want to save, highlight, and organize learning across YouTube, PDFs, and the web: Glasp is the stronger fit. Highlighting and knowledge management are its core.
• You want a fast transcript and a summary from a URL or an extension, with a choice of AI models: Glasp handles this well, including ChatGPT, Claude, and Mistral for summaries.
• You want transcript, summary, and open-ended chat with the current video, all in one panel on the YouTube page: Vidskim is built specifically for that in-page flow.
• You want transcript, translate, and export without any account gate or API key: Vidskim keeps those three free and never gated.
• You compare summaries across many AI models and want advanced summaries displayed on the video page as you watch: Glasp's paid tiers cover that.

A precise note on the chat row, because it matters: Glasp's checked pages verify follow-up questions for the AI summary model, Chat with PDF, and Ask AI Clone. They do not verify a dedicated open-ended chat-with-the-current-YouTube-video transcript workflow on the checked YouTube and pricing pages. That is not the same as saying Glasp has no chat or cannot ask follow-up questions, because it clearly can around its summary model and PDFs. It is a statement about what those two specific pages describe.

What Glasp does well

Glasp's YouTube transcript page is direct about what it offers, and it delivers a lot.

• Transcripts, fast and flexible. The page describes extracting and generating YouTube transcripts with one click, with timestamps, and no sign-up required for the online tool. You can copy, download, or save the transcript. There are options for a single YouTube video, a whole channel, and local audio.
• Two ways in. You can paste a video URL into the web tool to extract the transcript online, or install the free extension and click the transcript icon on any YouTube video page. Both give you the full timestamped transcript to copy, download, or highlight. The extension is offered for Chrome and Safari, with Edge, Brave, and Opera also mentioned.
• Model choice for summaries. Glasp lets you summarize with ChatGPT, Anthropic Claude, and Mistral AI, customize the prompt, and set the summary length, across multiple languages. If comparing model output matters to you, that flexibility is real.
• Basic and advanced summaries. The pricing page distinguishes basic YouTube summaries from advanced ones, where the advanced summary is displayed directly on the video page as you watch, with a customizable prompt.
• Highlighting and knowledge management. This is the part a narrow YouTube tool does not try to match. Glasp is built around highlighting, saving, and organizing what you read and watch, including unlimited public highlights on the free tier and daily auto-sync and export to Notion on paid tiers. If your goal is building a durable library of what you learn, that is a serious advantage.

If any of those describe your main use, Glasp is a good answer and you do not need an alternative.

Where Vidskim is different, not universally better

Vidskim makes a narrower bet. It is a Chrome extension focused on one page: the YouTube video you are watching. Everything lives there.

• One panel, on the video. Transcript, translate, export, one-click summary, and chat with the current video are all in the same place, next to the player. You do not switch to a separate web tool or paste a URL. That tight loop is the whole point.
• Open-ended chat with the current video. Beyond a fixed summary, you can ask the video questions in a conversation, following your own thread as you watch. This is the workflow Vidskim is built around.
• Free where it counts, and honest about the rest. Transcript, translate, and export are free and never gated. The one-click summary and chat currently run bring-your-own-key, meaning you connect your own API key and pay your provider directly for those calls. A hosted Vidskim plan is planned but not launched, so there is no price to quote for it yet.

Where Vidskim is not the better tool: if you want to highlight across many sources, keep a saved knowledge base, or sync to Notion, Glasp is built for that and Vidskim is not. Vidskim also works with the captions or transcripts a video already has; it does not claim to transcribe videos that have no captions available.

Pricing and free limits

Prices below are only from the live Glasp pricing page at glasp.co/pricing, checked 2026-07-04, showing the yearly billing view. Glasp notes that prices are in USD and that plans and pricing may change at any time.

• Free: $0, no credit card required. Includes unlimited public highlights, basic YouTube summaries at 3 summaries per day, YouTube channel tracking for 1 channel and 3 videos per channel, PDF uploads and summaries up to 30 files, PDF chat at 20 messages per month, and audio file transcription and summaries up to 30 minutes per month. Private highlights, advanced YouTube summaries, and daily auto-sync and export to Notion are not included.
• Pro: $12.50 USD/month, billed annually at $150/year (shown against a $180/year reference). Includes unlimited private highlights, unlimited basic YouTube summaries, advanced YouTube summaries up to 1,000 per month, channel tracking for 5 channels and 30 videos per channel, PDF uploads and summaries up to 100 files, PDF chat at 500 messages per month, audio transcription and summaries up to 300 minutes per month, and daily auto-sync and export to Notion.
• Unlimited: $30 USD/month, billed annually at $360/year (shown against a $432/year reference). Includes unlimited private highlights, unlimited basic YouTube summaries, advanced YouTube summaries up to 5,000 per 30 days, channel tracking for 25 channels and 500 videos per channel, unlimited PDF uploads and summaries, PDF chat at 5,000 messages per month, audio transcription and summaries up to 1,500 minutes per month, daily auto-sync and export to Notion, and priority support.

For Vidskim, the model is different rather than tier-based today. Transcript, translate, and export are free and never gated. Summary and chat run on your own API key for now, so your cost there is whatever your AI provider charges. A hosted plan is planned but not launched, and this article will not quote a price it does not have.

Which one should you choose?

• Choose Glasp if highlighting, saving, and organizing are central, if you want a web tool where you paste a URL as well as an extension, if you compare summaries across ChatGPT, Claude, and Mistral, or if advanced summaries on the video page and Notion sync matter to you.
• Choose Vidskim if you want the transcript, summary, and open-ended chat with the current video together in one panel on the YouTube page, if you want transcript, translate, and export free with no gate, and if you are comfortable connecting your own API key for the summary and chat features today.

Plenty of people will reasonably use both: Glasp as the long-term library, Vidskim as the fast in-page reader and chat while watching. They are not mutually exclusive.

Limitations both share

Neither tool is magic, and it is worth being clear about the shared ceilings.

• Captions and transcript availability. Both depend on a usable transcript for the video. If a video has no captions and no available transcript, summary and chat quality suffer for either tool. Vidskim does not claim to transcribe caption-less videos.
• Summaries are approximations. AI summaries compress, and they can miss nuance, drop context, or occasionally get a detail wrong. Treat them as a fast first pass, not a substitute for watching when accuracy really matters.
• AI costs and limits apply. Glasp meters summaries and chat by plan. Vidskim's summary and chat run on your own API key, so usage costs flow to your provider. Either way, heavy use has a cost.
• Third-party dependence. Both sit on top of YouTube and on AI models they do not own, and behavior can change when those change. Vidskim is independent and not affiliated with YouTube.
