Offline document AI for Android

Chat with your documents.Nothing leaves your phone.

Open a Word, Excel, PowerPoint, PDF or text file. Ask a question and get the answer from the document. Ask for a change and it appears as an edit you accept or reject. The AI runs on the phone itself, so after a one-time download it works with no internet connection.

How it works

Every change is a card you check first.

You ask in plain words. The assistant shows exactly what it wants to change, in red and green, and waits for you.

  1. Ask in plain words

    Type a question, or ask for a change: replace a word everywhere, add a sentence after a heading, delete a line, or set a spreadsheet cell.

  2. See the change before it happens

    Each edit shows as a card: the old text struck through, the new text underneath.

  3. Accept or reject

    Nothing changes until you accept, and Undo is one tap away.

  4. Save a copy

    Tap Save copy to keep the edited version, or share it. Your original file is never overwritten.

What you can do

Read less. Fix faster.

01

Ask about a document

When is the payment due? Summarise section 3. The answer comes from the document you opened.

02

Change it in plain words

Replace a word everywhere, add a sentence after a heading, delete a line, or set a spreadsheet cell. Every change waits for your yes.

03

Catch common mistakes

Built-in checks find repeated words, extra spaces, words spelled two ways, and unmatched brackets and quotes, with no AI needed. Or ask the assistant to check spelling and grammar.

04

Keep your original

Accepted changes go into a copy when you tap Save copy. Share the copy straight from the app. The file you opened stays as it was.

Private by design

Your documents stay on your phone.

The AI model runs on the phone itself. Your files, your questions and the answers are never uploaded.

Stays on your phone

  • Your documentsOpened with the Android file picker and read on the phone.
  • Your questions and the answersThe AI runs on the phone, so they are never sent anywhere.

Uses the internet

  • The one-time model downloadOver HTTPS from a public model host. Like any download, the host sees your IP address. The app sends no document, question or ID.
  • Google Play, if you buy ProGoogle handles the payment. The app never sees your card details.

Good to know

Questions, answered plainly.

Does it need the internet?

Only once, to download the AI model: about 340 MB for the Lite model, or about 980 MB for the Plus model. Use Wi-Fi if you can. After that it works with no connection. If you already have the model file, you can add it from the app instead.

Which phones does it run on?

A 64-bit Android phone with Android 8.0 or later. The larger Plus model needs a phone with about 12 GB of memory.

Which files can it open?

Word (DOCX), Excel (XLSX), PowerPoint (PPTX), PDF and plain text (TXT). PDFs are read-only: you can ask about them, but not edit them.

Will it change my original file?

No. Changes you accept are saved to a new copy when you tap Save copy. The file you opened is never overwritten.

Can the AI be wrong?

Yes. Check important facts against the document. If an answer is wrong, tap Report this answer: your own email app opens with the report filled in, and nothing is sent unless you send it.

Do I need an account?

No. There is no sign-in and there are no ads.

Your documents. Your phone.
