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

TLDRly

TLDRly does one job, one-click summaries and translation of whatever page or video you are on, and charges nothing for the core of it, unusual in a category full of credit-metered competitors. The trade-off is a thin operator footprint: the only named entity is an LLC on the store listing, the extension has a few hundred users and was last updated in November 2025, and the site and store disagree on whether paid options exist.

Pros

  • Core summaries are free with no account or card
  • Works across news sites, Wikipedia, Substack, Gmail and YouTube with one click
  • Translates into 40+ languages
  • Can summarize just a highlighted passage, not only the whole page

Cons

  • Chrome-only, with no extension for other browsers or a mobile app found
  • Small user base and no update since November 2025
  • Website says fully free while the store listing mentions premium options, so the business model is unclear
