AI models can make mistakes. Check important information.

How it works
Drop a PDF and chat with it or get a summary — powered by a small language model (Gemma 3 / Qwen2.5) that runs 100% in your browser. The document and your messages never leave your device. On-device models are small, so answers are best-effort.
Frequently asked questions
Is my document sent to a server?
No. The text is read and the model runs entirely in your browser.
Why are the answers sometimes off?
These are tiny on-device models (270M–1B). They are private and free but far less capable than large cloud models.
