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

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.
