Ad Marginem Docs

Browser Extension Quickstart

The browser extension captures papers from publisher sites and stores them in your library through the same API as the desktop app.

Install

  • Chrome / Edge: Chrome Web Store listing (coming with first public release).
  • Firefox: addons.mozilla.org listing (same).
  • Sideload (dev): clone the repo, run pnpm --filter @admarginem/extension build, then load apps/extension/dist as an unpacked extension.

Sign in

  1. Click the Ad Marginem icon in the toolbar.
  2. Click Sign in via api.admarginem.ca — a popup opens to the OAuth flow.
  3. Sign in with the same provider you used on desktop. The session cookie scoped to the API domain lights up both the desktop better-auth client and the extension’s fetch() calls — no token sharing needed.

If you’d rather skip sign-in for now, the extension queues captures locally (browser.storage.local) and uploads them once you sign in. The Options page surfaces the queue length.

Save your first paper

  • Click the icon while you’re on an arxiv.org / doi.org / publisher page → the popup shows the page metadata + a Save to Library button.
  • Right-click → Save to Ad Marginem on any link or selection.
  • Save attached PDF appears when the page exposes a citation_pdf_url meta tag or a same-origin .pdf link (P12.4).

Supported publishers

21 sites at launch: arXiv, bioRxiv, medRxiv, PubMed, doi.org, Semantic Scholar, ScienceDirect, Springer, Nature, Wiley, IEEE, ACM, JSTOR, SSRN, Taylor & Francis, SAGE, Oxford Academic, MIT Press, ASCE, AGU, plus a generic citation_*-tag extractor that covers most other academic publishers.

Options

  • Default citation style for inline citations.
  • Default save behaviour: try-CrossRef-DOI vs page-info-only vs ask-each-time.
  • Per-site enable/disable toggle in the Supported Sites list.
  • API server URL (override for self-hosting or staging).
