The margins are where the work happens.

Ad Marginem is a research workspace for the marginalia of academic reading. Your library, your highlights, your notes, and your citations — all of them in one place, all of them yours. Local-first. End-to-end. Across desktop, web, and your iPad.

What it does

• Reads PDFs with annotations that round-trip cleanly.
• Captures the web via the browser extension — one click per paper.
• Writes alongside with Word and a built-in editor that knows your library.
• Syncs across devices with conflict resolution that doesn't ask you to choose.
• Exports everything — your data is yours, on demand.

Why now

The dominant tools were built for a paper-library era. The way researchers actually read, annotate, and cite has moved on. Ad Marginem starts there: marginalia first, then everything else.
