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

tl;dr AI Summarizer

A tiny single-developer utility that does one job inside mobile Safari. It works from the share sheet with no account setup, and the free tier is one article a week, which is really a demo. Nothing has shipped since late 2023, so treat the roadmap as parked.

Pros

  • Works inline in mobile Safari rather than requiring a paste-in app
  • Summaries in six languages including Spanish, Chinese and Japanese
  • Free tier needs no account or card
  • Cheap in-app unlock compared with full writing suites

Cons

  • One free summary a week is barely usable unpaid
  • iOS only - the other platforms have been on a waitlist for years
  • App Store listing last updated in November 2023
