Not another answer in chat

Say what should change. See it happen in the file.

Select the exact target, describe the result, and review the edit where it belongs. You can revise, undo, or stop at any time.

Point to the exact content

Reference the whole file or select a paragraph, a cell range, a chart, or a few slides.

Keep the result in the file

The change lands in the active Word document, Excel workbook, or PowerPoint presentation—not in a separate answer you still have to move.

Edit it yourself at any time

Pause, revise, or undo the result. When you ask for another change, Buddy starts from the file you have now.

Files, permissions, and format limits

Know what Buddy can access—and what still needs your review.

You choose the files Buddy can work with. When a request needs AI generation, Buddy sends the prompt and relevant file content to the AI service you configured. Complex formats still need careful review.

You choose the files

You decide which files to open, which content to reference, and what Buddy should change.

Review every change

Pause the task, undo a change, adjust the result yourself, and decide when the file is ready to save.

Know the format limits

Complex Word layouts, financial models, and advanced PowerPoint animation still need careful review. Support is described by format, so you know where to check the result closely.

Common questions

A few things worth checking before you download.
