Quill – PDF and Document Chat

Quill is an AI research assistant that reads your PDFs and documents, then answers your questions. Works offline. Private by default.

That answer is buried in your document. Stop scrolling. Just ask.

Answers you can trust
Ask questions and get responses grounded in your actual content—not hallucinated facts. Quill finds relevant passages and generates answers based on what's written. Every answer links to the source so you can verify it yourself.

Your documents stay private
Free on-device AI (powered by Google's Gemma) keeps everything on your phone. Nothing uploaded. No account required. Premium cloud AI is optional—your choice, your control.

Find it without knowing the exact words
Search for "compensation" and find passages about "salary." Ask about "termination clauses" and find "ending the agreement." Quill understands meaning, not just keywords.

Works offline
Study and research on airplanes, in subways, anywhere. On-device AI needs no internet after setup.
