What our research says

Claras

Solves a narrow annoyance well: not having to scrub a long YouTube video to find one answer, now extended to whole playlists at once. It is cheap, but the free plan shrank to three videos a month, so anyone using it regularly will be paying from the first week. The $0.95 three-day pass is a fair way to find out first.

Pros

  • Chapter-linked summaries plus a chat that cites timestamps
  • Bulk summaries across a playlist, channel or search page
  • Cheap paid plans and a $0.95 three-day pass instead of a long trial
  • Exports to TXT, PDF and SRT or straight into ChatGPT, Claude, Gemini and NotebookLM

Cons

  • Free plan is only 3 videos a month
  • Chrome-only extension, though a paste-a-link web version exists
  • Solo-founder product, so longevity and support capacity are unproven

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

Which one fits

  • Users who want answers tied to timestamps rather than a plain summary

Choose Glasp if you need

  • Students and researchers collecting cited passages across the web and PDFs
  • Writers keeping a swipe file of quotes for drafting with ChatGPT or Claude
  • Readers who want Kindle and web highlights in one library
