Paper Anchor
A self-hosted, citation-anchored reader for academic papers: every LLM answer links back to the exact highlighted passage in the source PDF.
- Citation-integrity eval
- 15 / 15
- Bilingual UI
- EN / zh-TW
- 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.
