What would make you trust AI with your existing Word, Excel and PowerPoint files?

A client changes the brief. The proposal, budget and slides all need updating. Which part would you let AI handle—and which part would you still check yourself?

We’re building Oh!Mate, a desktop AI workspace for this kind of work. Our demo follows one change across Word, Excel and PowerPoint, with a focus on targeted edits and keeping the formatting you already have. You can also turn a useful workflow into a reusable skill.

Three useful first tests:

• Proposal: “Move the delivery date to November 19. Keep the existing layout and save an updated copy.”

• Budget: “Update the production cost to 9,800. Preserve the formulas and explain which totals changed.”

• Slides: “Update the budget slide to match this spreadsheet. Keep the theme, typography and slide order.”

Start with a copy of a file, make one clear request, then open the result and check it. The Free plan includes 40 credits every 7 days.

What would earn your trust: preserved formatting, a clear explanation of changes, formula checks, or something else? Tell us the file type and the change you need. A made-up example is perfect—please leave private client information out of the thread.
