PaperTrail
AI-powered research paper discovery, semantic search, and RAG-based Q&A over arXiv papers.
PaperTrail automatically fetches papers from arXiv, builds a semantic search index, and lets you ask research questions to receive LLM-synthesised, citation-backed answers.
Features
| Capability | Description |
|---|---|
| Ingest | Fetch arXiv papers by category, download PDFs, extract + clean text, create embeddings |
| Semantic Search | Find relevant paper chunks with cosine similarity (FAISS) + reranking |
| Q&A / Ask | RAG-based question answering grounded in your paper corpus |
| Research Report | Full pipeline: plan → retrieve → synthesise → critique → evaluate |
| Trends | Surface trending keywords and categories across indexed papers |
| Offline-first | Embeddings run locally (no API key needed for ingest + search) |
