Glasp
Highlight the web, PDFs, YouTube, and Kindle, then query your own marked-up ideas with AI.
Glasp is the right pick if you read a lot on the open web and want a public paper trail plus AI recall on top of it. The March 2026 MCP connector is the standout feature — it brings your highlights into ChatGPT or Claude instead of forcing you to work inside a new silo. Export breadth (Notion, Obsidian, Roam, Tana, Workflowy, Zotero, plus Markdown and JSON) means you are not trapped. The rebuilt 2026 mobile apps and the five-browser extension coverage remove the usual capture friction. Where it loses: if you need structured note-taking, Obsidian or Notion beat it, and if you want everything private by default, Hypothesis or a local tool will feel safer. Pick Glasp for discovery and AI Q&A,

Skip Glasp if you need backlinks, block references, and daily-note architecture in one tool — Obsidian or Notion will serve you better as the thinking layer.
As a free-first tool, Glasp competes against paid read-later and highlight products like Readwise and Matter. If you only need capture and export, the free entry point covers it; if you want the AI layer and private highlights, you are comparing against the paid tiers of Readwise and Hypothesis rather than against Pocket or Raindrop, which are cheaper but lack the AI chat and MCP bridge.

About Glasp
Glasp is a social web and PDF highlighter that turns everyday reading into a searchable, AI-queryable knowledge base. You install a browser extension for Chrome, Safari, Edge, Brave, Firefox, or Opera, or use the rebuilt 2026 iOS and Android apps, then select text on any page, PDF, YouTube video, or Kindle book. Every highlight lands in one library that you can tag, search by author, or export. What separates Glasp from private clippers is the public layer: you can follow other people and see what they highlighted, so the tool doubles as a discovery feed. AI features include one-click summaries of articles, PDFs, and YouTube videos, a chat that answers questions against your saved highlights, and a March 2026 MCP connector that pipes your highlights into ChatGPT and Claude. Import options cover Kindle, Pocket, Readwise, Raindrop, Instapaper, Matter, Medium, Snipd, Hypothesis, Weava, Diigo, Wallabag, and CSV; export goes to Notion, Obsidian, Readwise, Roam, Tana, Workflowy, Zotero, plus Markdown, HTML, CSV, JSON, API, and MCP. It suits researchers, students, writers, and lifelong learners who read to think, not people who need wiki-style note structuring.
Behind the Verdict
Glasp's pitch is narrow and honest: it is a highlighter first, an AI layer second, and a note-taking app never. The capture surface is the strongest part. You get one extension that works in Chrome, Safari, Edge, Brave, Firefox, and Opera, plus native iOS and Android apps rebuilt from scratch in early 2026 with a reader view, YouTube transcripts, widgets, and an iOS Safari extension. That combination covers the places most people actually read, which is more than most competitors manage. The AI layer is grounded in your own highlights rather than the open internet, so summaries and chat answers stay close to what you flagged. The MCP connector launched on 2026-03-01 is the most consequential addition — it exposes your highlights to ChatGPT and Claude, which means you can keep your assistant of choice and still query your library. Export is unusually generous: Notion, Obsidian, Readwise, Roam, Tana, Workflowy, Zotero, Markdown, HTML, CSV, JSON, plus API and MCP. Import is just as wide, covering Kindle, Pocket, Readwise, Raindrop, Instapaper, Matter, Medium, Snipd, Hypothesis, Weava, Diigo, Wallabag, and CSV, so migrating in from a dead or backup tool is realistic. The social dimension is genuinely differentiating. Following other highlighters and browsing a knowledge graph of what you read gives you discovery that Raindrop.io and Pocket don't offer. The trade-offs are real. The social feed is thin compared to a real social network — think shared notebooks, not a timeline you scroll for hours. AI output is only as good as what you fed it, and the chat is grounded strictly in your highlights, so it will not fill gaps for you. There is no structured note architecture: no backlinks, no block references, no daily notes. If your workflow needs that, use Glasp as the capture front-end and keep Obsidian or Notion as the thinking layer. The data you keep is also the data you can accidentally publish, so the privacy-minded should decide what stays private before highlighting sensitive material. Overall: a solid capture-plus-recall tool for readers who want their highlights to do more than sit in a folder.

Real-world workflow fit
Concrete scenarios for the personas Glasp actually fits — and what changes day-one when you adopt it.
Reads 40 papers and 60 web articles in a month, highlighting methods and findings, then asks the AI chat which papers share an experimental design.
Outcome: Builds a tagged, searchable evidence library and writes a literature review section without re-reading everything.
Highlights quotes across articles in Chrome through the week, then exports the week's highlights to Notion and asks ChatGPT about them via the MCP connector.
Outcome: Ships a weekly issue from a swipe file of quotes and ideas instead of scrambling for links.
Highlights lecture PDFs and YouTube lectures on the iOS app, tagging them by course, then revisits summaries before exams.
Outcome: Turns passive lecture watching into reviewable notes grounded in actual quotes.
Use Cases
- Highlight ten YouTube videos this week and ask the AI what themes recur across them.
- Build a research notebook for a paper across 50 webpages and 20 PDFs, then chat with the library.
- Capture supporting quotes for a blog post straight from the browser as you read.
- Export a year of highlights to Notion as a personal knowledge base.
- Feed highlights into ChatGPT or Claude via MCP for AI Q&A inside your existing assistant.
- Follow researchers in your field and study what they highlight each week.
Models Under the Hood
as of 2026-08-31
Limitations
- The social layer is thin compared to a real social network — closer to shared notebooks than a scrolling feed.
- AI summary and chat quality depends entirely on what you highlighted, so weak highlights produce weak answers.
- Chat is grounded only in your saved material and will not fill gaps for you.
- There is no offline mode on the mobile apps.
- There is no structured note architecture: no backlinks, block references, or daily notes, so it cannot replace Obsidian or Notion for wiki-style work.
- Because your profile is public by default in the social layer, sensitive material needs thought before you highlight it.

Where the pricing makes sense
The company stage and team size where Glasp's pricing actually pencils out — and where peers do it cheaper.
As a free-first tool, Glasp competes against paid read-later and highlight products like Readwise and Matter. If you only need capture and export, the free entry point covers it; if you want the AI layer and private highlights, you are comparing against the paid tiers of Readwise and Hypothesis rather than against Pocket or Raindrop, which are cheaper but lack the AI chat and MCP bridge.
Setup time & first value
How long it actually takes to get something useful out of Glasp — broken out by persona, not the marketing-page minute.
Install the browser extension and you can highlight your first page in under two minutes. Connecting imports (Kindle, Readwise, Instapaper) or export targets (Notion, Obsidian) takes another five to ten minutes. Wiring the MCP connector into ChatGPT or Claude is a short configuration step for anyone who has added a connector before.
