Overview

Highlight, annotate, and organize text on any website. Focus mode, find-all, dark mode support. Local-first, no account needed.

Web Highlighter turns any webpage into your personal study space. Select text and highlight it in 5 colors, add notes with one-click quick tags like [Important] or [Review Later], and organize everything in a clean sidebar — no account needed, ever. Use Focus Mode to dim the entire page and spotlight your highlights one by one, perfect for reviewing research or studying before exams. Found a key term? Hit Find All to highlight every occurrence instantly. Customize what each color means, copy your notes as Markdown, export and import highlights as JSON, and enjoy full keyboard shortcut support. Works beautifully on dark mode sites. Everything stays 100% local in your browser. No servers, no tracking, no sign-ups. Just highlight and go.
