Chat with your PDFs, URLs & images — with private vaults and admin quotas.
DocuChat (aka Universal RAG Chat) indexes your private uploads and selected public docs, re‑ranks with a cross‑encoder, and answers using your preferred LLM.
How DocuChat Works
1) INGEST
Upload PDFs, PPTX, DOCX, images, CSV/Excel — or paste URLs. We normalize, parse and OCR scans.
2) INDEX
Chunk + embed to FAISS. Optional cross‑encoder reranking improves grounded answers.
3) ASK
Ask grounded questions; we retrieve passages with citations. Image panels preview figures.
4) ADMIN & QUOTAS
Per‑user limits on files, storage and URLs. Lightweight admin view for public registry and usage.
