Features

Highlight & organize

Colored highlights, Markdown notes, bookmarks, nested collections and flashcards. Save articles and PDFs for offline reading.

Import and export

Import Markdown. Export to Markdown, Notion-ready files or structured AI-agent bundles. Download complete backups, optionally encrypted.

Local storage

No account is required for local research. No telemetry, advertising or developer-operated research server.

Optional Google Drive sync

Connect your Google account only if you want to synchronize research between installations. Margin requests drive.appdata, which accesses its own hidden app-data folder rather than unrelated Drive documents.

When connected, saved URLs, quotations, notes, articles, PDFs, audio, cards and preferences are sent to Google Drive. Margin adds no end-to-end encryption to sync. Your Google storage quota applies. You can pause or disconnect sync and keep working locally.

GitHub downloads include Google sign-in. Open Settings & backups, choose Continue with Google and approve Margin’s own Drive folder. Older downloads may need a separately configured build.
