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

MurmurCast

MurmurCast is useful if you already follow a fixed set of channels, podcasts, and newsletters and want one inbox digest instead of checking each source. The catch is the free tier's low caps make it mostly a trial before you're pushed into a paid plan within the first month of real use.

Pros

  • Covers five different content types (video, podcast, newsletter, papers, filings) in one digest
  • On-demand transcription for any single YouTube URL
  • Full-text search across everything archived
  • Free tier requires no payment to start

Cons

  • Free tier limits (5 sources, 20 episodes/month) are tight for heavy users
  • No mobile app or browser extension, only a web/email workflow
  • No API for pulling data into other tools
