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

Liner

Liner is a good fit for students and researchers who want cited answers and a paper finder in one subscription, and who will actually click through the sources. Casual users happy with a general chatbot, or anyone who dislikes ads and tight credit limits on the free plan, will find less value.

Pros

  • Sentence-level citations make answers checkable
  • Scholar mode focuses search on academic papers
  • Paid plans include many third-party chat and image models
  • Annual billing brings Pro under $15 a month

Cons

  • Free credits run out after a few tasks and answers show ads
  • No refunds on subscriptions
  • Product spans search, scholar and writing, which can blur what each plan unlocks
