Does AI-Powered PPT Creation Actually Save Time?

Last Wednesday night, I was pressured by a client for a 5G baseband power consumption optimization report. It wasn't that I lacked data; it was that there were too many diagrams. I threw the materials into an AI PPT tool to try a version. The text looked decent, but the diagrams were garbage. The "power wall problem" was drawn as a brick wall, with a cartoon light bulb next to it. This thing is still one process node away from replacing PowerPoint.

I mainly tested Gamma and also opened Copilot within PowerPoint. Copilot is the AI assistant embedded in PowerPoint. Inputting "write a chip power optimization report," it first produces a table of contents, then bullet points for each page. The interface has an outline on the left, pages in the middle, and styles on the right. The surprise is that it can parse Markdown outlines. Markdown is that lightweight text format with hashtags and hyphens. At least you don't start from a blank page.

The bottlenecks are also obvious. I uploaded a document with block diagrams; the tool could read the text but failed at reading the images. Arrows and module relationships were completely lost.

Exporting to .pptx (PowerPoint format) and returning to local software resulted in misaligned layouts. Fonts were missing, color blocks turned gray, and table borders broke. This feels like discovering inconsistent package pin definitions after tape-out.

Microsoft Copilot is not a PowerPoint replacement, but rather adding AI to PowerPoint.

I agree with this statement. Copilot's value isn't replacement, but saving a few mouse clicks. What truly feels like a replacement are tools like Gamma and Canva. They generate from outlines, and their template systems are relatively complete. A template system is pre-arranged page styles that try to maintain fonts, spacing, and colors when swapping content. For those who can't design, it is indeed convenient.

There are three pros. Fast first drafts. I can produce an editable outline in ten minutes. Text editing is smooth. Changing titles and paragraphs is more comfortable than PowerPoint's text boxes. Export formats are becoming more serious. Many tools support .pptx; although imperfect, they can at least enter company workflows.

There are also many cons. Charts are basically unusable. Block diagrams, flowcharts, and timing diagrams are often drawn by AI as decorative images. Style control is not granular. Manually moving a text box might break the template logic. I previously wrote about SHEIN getting stuck on frontend state machines when changing addresses; this is similar: surface buttons, underlying states unsynchronized. Collaboration and version control are not as mature as PowerPoint. Some say they edited it, some say they didn't see it, and finally, it relies on file naming.

Some people's needs are actually very plain: text editing should best support Markdown, allow image modification, control styles, have a template system, and support desktop drag-and-drop editing.

No tool today fully meets these needs. Gamma leans toward generation and layout, Copilot leans toward the PowerPoint ecosystem, and Canva leans toward templates and branding. They are like different process nodes: some save area, some save power, some look good on paper metrics.

Who is it suitable for? Suitable for product managers, marketing, and pre-sales personnel who need to quickly turn meeting notes and proposal highlights into first drafts. Less suitable for technical reviews like chips, architecture, and testing. The core of technical reports isn't text, but diagrams, tables, and logical relationships. AI can spin words well, but it can't draw accurate block diagrams.

Conclusion: It depends, but don't treat it as a final draft tool. If you just need a first draft that looks like a PPT, AI can save a lot of time. If you're going to present on stage, you still need to return to PowerPoint or Keynote for manual alignment. Suggestion: Use AI to generate outlines and text first, leaving whitespace for chart positions; after exporting to .pptx, redo the block diagrams, tables, and key pages.
