Marklight: Web Highlighter — Highlight Text & Notes

Highlight text on any web page and add notes. Local-first: your highlights never leave your device. No account needed.

Marklight is a web highlighter that treats your notes like they're yours. Select text on any web page, press Alt+H (or right-click → Highlight), and it's saved — on your device, in your browser, with no account, no sign-up, and no AI upsell. WHY MARKLIGHT ★ Never lose a highlight. If a page changes, Marklight keeps your highlight and marks it "page changed" instead of silently deleting it. One-click local backup and restore included — your notes survive even a reinstall. ★ No account. Ever. Install and highlight 5 seconds later. Nothing is uploaded; there is no server. ★ Fast and quiet. No sidebars hijacking your reading, no sign-in walls, no "upgrade to AI" pop-ups. FEATURES (FREE) • Highlight in 4 colors — keyboard shortcut, right-click menu • Add a note to any highlight • Highlights restore automatically when you revisit a page (works on dynamic sites and single-page apps) • Library view: every highlight on every page, with full-text search • Copy a page's highlights as clean Markdown • Local backup & restore (JSON file you own) MARKLIGHT PRO (one-time purchase — not a subscription) • Export your entire library at once • Notion- and Obsidian-ready export formats • Support an independent developer PRIVACY Marklight stores everything in your browser's local storage. No analytics, no tracking, no remote servers. The only network access happens if you choose to buy Pro (payment is handled by ExtensionPay/Stripe).

Marklight does one job — highlighting — and does it reliably.
