What it took
  • A bbox-level citation-anchoring pipeline — PDF chunking, embedding, retrieval — built without LangChain.
  • Two-pane reader with select-to-ask: explain, translate or challenge any passage.
  • Provider-agnostic backend: any OpenAI-compatible API, with embeddings that can run fully local and keyless.
