LocalDocs - Your Private AI

Mystum

About this app

LocalDocs turns your own documents into a question-and-answer assistant - and it runs entirely on your phone. No account. No cloud. No internet needed after setup. Your files never leave your device.

Put your PDFs, Word files, notes, images, and drawings into a folder, then just ask. LocalDocs reads across everything in that folder and answers in plain language, showing you exactly which document each answer came from.

WHAT YOU CAN DO
• Ask questions across all the documents in a folder at once
• Get answers with sources you can tap to open
• Works with PDF, Word (.docx), text, Markdown, HTML, images, and drawings
• Organize your files into folders, like mini libraries
• Copy, share, or have any answer read aloud
• Works 100% offline after a one-time setup

PRIVATE BY DESIGN
• Everything is processed on your device by an on-device AI model
• No accounts, no analytics, no advertising, no tracking
• Your documents and chats are stored encrypted on your device and are never uploaded
• The only thing that ever leaves your phone is a report you choose to send about a bad answer — and only when you tap Submit

HOW IT WORKS
On first launch, LocalDocs downloads the AI model it runs — a few hundred megabytes, one time, best done on Wi-Fi. After that, it works fully offline. For the best experience, use a recent 64-bit Android device with enough free storage and memory.

GREAT FOR
Studying and revision, research papers, contracts and policies, manuals and guides, reports, and any pile of documents you'd rather ask than scroll through — all kept private on your device.

LocalDocs is a one-time purchase. No subscriptions, no ads, no hidden costs.

What’s new

LocalDocs answers questions about your own PDFs, notes, and documents — fully on your device, private and offline, in 34 languages. This build focuses on reliability and stability improvements.
