Litmark από Aaron Ye

Litmark lets you highlight text on any website — select a passage, pick a color, and it's saved automatically. Revisit that page later and your highlights reappear right where you left them, even if the page has changed slightly.

Manage everything from one popup: see every page you've highlighted, jump back to any of them, delete a single highlight or clear a whole page, and export or import your highlights as a JSON file.

Litmark has no server and makes no network requests. Everything stays in your browser's local storage — no accounts, no analytics, no tracking of any kind.

Features:
- Five highlight colors
- Highlights survive minor page edits (text-quote matching, not fragile position tracking)
- One-click removal, on the page or from the popup
- Export/import your highlights as JSON
- 100% local — nothing leaves your device
