carbon

Carbon turns arXiv links, PDFs, and research pages into a personal research workspace. It extracts metadata, stores papers in a shared Supabase-backed library, generates AI summaries and credibility scores, builds a similarity graph, and lets you ask grounded questions about each paper.

The app is built with Next.js 16, React 19, Supabase Auth/Postgres/Storage, OpenRouter-hosted LLM calls, Sigma.js graph rendering, and an embedded PDF reader.
