NoteMarker

Highlight and annotate any webpage, saved to your local notemarker knowledge base

NoteMarker — Highlight, annotate, and save the web. Locally. Everything you mark is stored as plain files on your own computer — no account, no cloud, no upload. FEATURES • Highlight & annotate — Select text on any webpage to highlight it in multiple colors and attach notes. • Save pages — Clip the whole page or just a selected region. Images are saved together with the text, so pages stay readable as rich mixed content. • Manage your reading — Reading list with unread/archive states, annotation manager with search and filters, and one-click export to JSON or Markdown. YOUR DATA, YOUR MACHINE • Files, not a silo — Every highlight, note, and clipped page is written to your local disk as ordinary files. Open, back up, or process them with any tool. • 100% local — Nothing ever leaves your device. No sign-up, no login, no external server. • Full control — Migrate, back up, or delete your data at any time. It's yours. • Database is only a cache — The local index exists purely to speed up search. Delete and rebuild it at any time; your source files always remain complete. NoteMarker pairs with a small open-source local server (github.com/mechine/NoteMarker). The extension includes a built-in quick-start guide — set up once, and your knowledge base stays on your machine.
