Ask a question. Your PDFs answer.
RefChat reads your articles, reports and patents, then answers while citing its sources. 100% local for your sensitive data, or on a secure European cloud.
Hundreds of reports, thousands of pages. Just ask: the sourced answer arrives in seconds — instead of digging for hours.
How it works
From your PDFs to your answers, in 3 steps
No technical skills required. Your files stay exactly where they are.
Point to your folder
Tell RefChat which folder holds your PDFs (Zotero, Mendeley, or a plain Windows folder). Nothing to upload.
RefChat reads them
It reads and indexes every article — text, tables and scanned PDFs included. Once, in the background.
Ask your questions
Chat with your library in natural language. Every answer cites the exact article and page.
Why RefChat
Three differences that matter
Not yet-another-ChatGPT for PDFs. A tool built for scientific rigour and data confidentiality.
100% local option
Your sensitive documents never leave your machine. Cloud mode available if you prefer performance.
Compare local vs cloud →Hybrid, source-cited search
Semantic + keywords + reranking. More accurate than a basic RAG, and every answer cites its exact sources.
See features →Made and hosted in France
Documented GDPR compliance, no model training on your content. Cloud runs on OVHcloud (Roubaix).
