About

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.

Features

1

Ask a whole folder at once

Pose a question and LocalDocs reads across every document in the folder to answer it.

2

Answers with tappable sources

Every reply cites the document it came from — tap the source to open and verify it.

3

Works with your file types

PDF, Word (.docx), text, Markdown, HTML — plus images and hand-drawn sketches.

4

100% on-device & private

Processed by an on-device AI model: no accounts, no analytics, no tracking. Your documents and chats stay encrypted on your phone and are never uploaded.

5

Copy, share, or listen

Copy an answer, share it, or have it read aloud — and organize your files into folders like mini libraries.
