Growth was led by enterprise renewals, with average deal size rising 12% quarter-over-quarter across the segment.
Grounded in your sources
Answers come from your files, not the model's memory.
Page-level citations
Every claim links to the exact page it came from.
Real-time streaming
Answers appear token by token — no waiting.
Multi-document synthesis
Ask one question across many files at once.
Cited by page, not by vibe
Every answer is grounded in your documents and points to the exact page it came from — trace any claim back to its source in one click.
Streams in real time
Token-by-token responses over server-sent events — no spinners, no waiting for the full reply.
Compares across documents
Select multiple PDFs and ask one question across all of them — synthesis, not just retrieval.
Remembers the thread
Pinned documents and persistent sessions — pick up any research conversation exactly where you left it, days later.
Not another AI chatbot
Most tools either chat without proof, or read PDFs without memory. Querex is built to do both — grounded answers, kept in context.

How it works
Upload
Drop in a PDF — it's parsed page by page and embedded into a private vector index.
Ask
Ask in plain language. Retrieval finds the passages that actually answer your question.
Verify
Every answer streams in with a page citation, so you can check it against the source.
Built in the open
No walled garden, no black box. The full source — retrieval pipeline, auth, admin panel, and all — is on GitHub for anyone to read, audit, or run themselves.
Fully open source
The complete codebase is public. Read every line, or self-host your own instance.
Covered by automated tests
Auth, retention, admin access, and RAG contracts run in CI on every change.
Security-hardened by default
httpOnly sessions, rate limiting, and brute-force protection — not bolted on later.
Stop skimming. Start asking.
