Ask about a document
When is the payment due?
Summarise section 3.
The answer comes from the document you opened.
Offline document AI for Android
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
You ask in plain words. The assistant shows exactly what it wants to change, in red and green, and waits for you.
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.
Each edit shows as a card: the old text struck through, the new text underneath.
Nothing changes until you accept, and Undo is one tap away.
Tap Save copy to keep the edited version, or share it. Your original file is never overwritten.

What you can do
When is the payment due?
Summarise section 3.
The answer comes from the document you opened.
Replace a word everywhere, add a sentence after a heading, delete a line, or set a spreadsheet cell. Every change waits for your yes.
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.
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.
