AI slide tools give you a first draft in ten minutes. The time leaks out afterwards, when you fit it to the client template and move it into PowerPoint. Here is where it leaks and what changes when you pick the template first.
The night before a proposal is due, you give an AI slide tool an outline. Ten minutes later you have ten slides. So far so good. But the deck is not in the client template. The colors are whatever the tool picked, and the font is not the one the client specified. So you export to PowerPoint and open it. Every slide has something to fix: recolor, repair a title that wraps badly, shrink text that spilled out of its box. The draft took ten minutes and the cleanup takes half a day.
Today’s AI tools are strong at producing content and leave the formatting to you.
The same request shows up again and again in what people write. One r/powerpoint user put it this way: "I personally need an AI that can automate the format work in extremely precise templates but I do not want it to write the content." (2026-02) The faster AI produces content, the bigger the formatting work looks by comparison. A file that looks different on another computer adds to it. A Microsoft Q&A question describes random line breaks in titles even when the recipient has the font (2022-08), and tools differ in how much formatting information, such as masters and fonts, they carry into an exported file. What they share is that the formatting work piles up right before the deadline.
Try changing the order in which you hand work to the AI.
In getdeck the layouts and themes exist first, and swapping a theme onto the same slide shows you the result at once. You can switch themes in the gallery without logging in. Type a client color as a HEX value under "+ New theme" and the slide picks it up immediately. Saving the theme is a Pro feature. Export produces a PPTX, and the text goes in as text boxes, not images. The person who receives the file can fix a typo in PowerPoint themselves.
It fits people who write the content themselves and want to spend less time on formatting. It cannot read a .potx master file a client gives you and use it as is. For that, keep using the PowerPoint master.
