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

Tubly

The useful part is not the summary — everyone does summaries — it is that the chapters link back to the timestamp, so the summary is a table of contents rather than a replacement for watching. At five dollars a month with the extension running on every watch page it is priced like a browser utility, which is what it is.

Pros

  • Chapters and topics deep-link to the exact second on YouTube
  • Full editable transcripts exportable in one click
  • Chat panel answers questions against the video on the watch page itself
  • Saved highlights and timestamp clips persist without replaying the video
  • Flat $4.99 a month with no credit metering

Cons

  • No free tier — only a trial, then the card is charged automatically
  • No refunds for partial billing periods, per the terms
  • Company details are limited to a Brazilian governing-law clause; no registered entity is named
  • Nothing outside YouTube is supported
