Episteme
RAG-powered Chrome extension for verifying article claims
Readers have no fast way to tell whether an article's claims are original, already contradicted elsewhere, or just repeating what's already been said, without leaving the page to go check.
Built the full RAG pipeline inside a Chrome extension: LLM-based thesis extraction, 768-dimensional embeddings, and pgvector cosine search against a Supabase vector store, plus an in-page AI chat for follow-up questions.
An extension that classifies the 3 nearest related articles as supporting, contradicting, or extending the current thesis, verifying every claim against verbatim source text before it's persisted.
