What our research says

Glasp

Glasp fits students, researchers and writers who read a lot online and want every quote kept with its source and searchable later. People who want their reading private by default, or who mostly need a full note editor rather than a highlighter, should look elsewhere.

Pros

  • Free plan keeps unlimited highlighting plus exports and Notion sync
  • Works across Chrome, Safari, Edge, Brave, Firefox, Opera and mobile
  • Each highlight keeps its source metadata, so quotes stay cited
  • MCP connector and API make the library usable from other AI tools

Cons

  • Highlights are public by default; privacy is a paid feature
  • Free AI allowances are small, especially video summaries
  • Social feed is of limited use to people who read alone

Unfurl

Unfurl is built for the moment when a YouTube video is worth more than a passive watch — it turns the transcript into chapters, a chat tutor, and a concrete action plan. The trade-off is the credit system: longer videos and heavier use eat through the entry-level plans quickly, and output quality depends entirely on the source video having a usable transcript.

Pros

  • Produces a concrete action plan, not just a summary
  • Chat tutor is grounded in the actual transcript rather than general knowledge
  • Telegram bot works without opening the web app
  • Unused pay-as-you-go credits don't expire

Cons

  • Credit consumption scales with video length, so long-form content gets expensive
  • No native mobile app or browser extension
  • No public information on the company behind the product
