About ZetaMarker - PDF & Web Highlighter
Highlight web pages and PDFs, add notes, and build a searchable research library. Start locally with no account required, then sync across devices when you're ready. PERFECT FOR • Researchers • Students • Developers • Knowledge workers • Anyone who reads extensively online 🔒 PRIVACY-FIRST — YOU CHOOSE WHERE IT RUNS Many highlighter extensions ask for broad permission to "read and change all your data on all websites." ZetaMarker doesn't. ZetaMarker uses a limited-permission approach: it only runs on pages where you turn it on — with a click on the extension icon or a keyboard shortcut. It does not watch every tab you open, and it does not annotate sites you haven't activated. That means banking, email, healthcare portals, and work apps stay private by default.
