Highlight the web. Keep the idea, source and context.

Bookmarks save pages. You needed the idea inside the page.

- ✓ Save an exact passage without leaving the page
- ✓ Return to the original article and highlighted context
- ✓ Group multiple highlights from the same article
- ✓ Add a personal note or send the highlight to a knowledge base
