About this app

Meet the PDF app that organizes itself — and not just PDFs. On-device AI sorts your PDFs, Word, Excel and PowerPoint files into tidy categories, answers questions about any document, and translates — with a full set of reading and editing tools, all in one private app.

★ AI ORGANIZE — your whole library, sorted for you
On-device AI reads your PDFs, Word, Excel and PowerPoint files and files them into clear categories automatically. No manual tagging, no endless folders — and your real files are never moved, renamed, or deleted.

★ ASK AI — chat with any document
Get instant answers, summaries, and explanations from any PDF. Just bring your own Google Gemini key; it stays on your device.

★ TRANSLATE, RIGHT ON YOUR PHONE
Translate documents into your language on-device — no key, no account, nothing uploaded.

★ READ & ANNOTATE
Open PDF, Word, Excel, PowerPoint and text files. Highlight, draw, add shapes, signatures, stamps, notes and text; insert images and rotate pages. Night & sepia modes and full-text search.

★ EVERYDAY PDF TOOLS
Scan paper to PDF, merge, split, reorder pages, password-protect, and export pages as images.

★ PRIVATE BY DESIGN
Your files stay on your device and aren't uploaded to our servers. Cloud AI is optional and uses your own key.

Clean Material design, 15 languages. Turn document chaos into calm.
