What is Glasp?
Glasp lets you highlight and annotate articles, PDFs and YouTube videos straight in the browser, then collects everything into one searchable library you can export to your notes app. It also shows what other people highlighted on the same page, which is a surprisingly good discovery loop.
Pros: what Glasp does well
- Free and quick to start
- Exports cleanly to Obsidian and Notion
- Highlights YouTube transcripts too
Cons: where it falls short
- Highlights are public by default unless changed
- Lighter than a full read-later app
Who Glasp is for
Readers who want their highlights to end up somewhere useful.
Who can skip it
People already deep in a Readwise workflow.
