Open PaperTok · Latest release · Report a bug

PaperTok helps you find research when you don't know what to search for. Pick your fields, scroll, and the feed learns from what you read, like, save, skip and follow.

PaperTok is under active development. It is not affiliated with arXiv, OpenAlex, PubMed or any other data provider.

Features

• Personalized feed from arXiv, OpenAlex, PubMed, OpenReview, Hugging Face and more.
• Follow authors, topics, institutions and projects.
• Search papers, authors, topics, institutions and projects with /.
• Similar papers from the card’s action rail.
• Read in plain words: AI rewrites at Beginner, University or Researcher level when supported full text is available, with highlights and notes.
• University library access: verify a university email to read articles your library confirms access to. Coverage depends on your institution, article and subscription year.
• Citation map: see what a paper cites and what cites it.
• Clear labels for preprints, working papers and open access.
• Library of colored lists you can share.
• Weekly email update: an opt-in reading list prepared on Mondays with new papers from what you follow. Delivery can be delayed by sending limits.

Run locally

Requires Node 22.18 or later.

git clone https://github.com/mugar123/papertok.git
cd papertok
npm ci
cp .env.example .env.local
npm run dev

The example points the frontend at a local Cloudflare Worker. Start it with npx wrangler dev --local --port 8787; provider credentials belong in the ignored .dev.vars file, as described in worker/README.md. Firebase web configuration is already bundled in src/services/firebase.ts.

For signed-in development, use npm run dev:emulators with firebase-tools and Java 21 or later. It starts local Auth and Firestore emulators and signs in a disposable account; Worker routes that require production identity reject its tokens. See the local testing guide for account switching and limits.

Run npm run check before opening a pull request.
