AI slide tools have come a long way. Tools like Gamma, Canva Magic Design, and ChatGPT can turn a rough outline into a full deck in minutes. If you’re short on time or staring at a blank screen, that’s a life saver.
But here’s the catch: most AI-generated decks share the same handful of habits. Centered text on a soft gradient. A stock icon parked next to every single bullet. A font pairing that looks a little too familiar because thousands of other decks are using it right now too.
Your audience might not be able to name what’s off, but they’ll feel it. And in a business setting, a deck that looks like everyone else’s doesn’t do much to build trust in your brand.
The good news: the AI-generated version is a solid first draft, not a finished product. A little intentional editing goes a long way toward making it look like you actually made it. Here’s where to focus.
Fix the Visuals
Swap the default fonts. AI tools default to a small handful of “safe” font pairings, and you’ve probably seen them all before. Pick two fonts that match your brand (one for headings, one for body text) and use them consistently across every slide.
Cut the color palette down. AI tools love adding extra gradients, shadows, and accent colors that nobody asked for. Stick to 3-4 colors max per deck, ideally your actual brand colors. This alone makes a deck look far more deliberate.
Replace the generic icons. This is probably the single biggest giveaway. Those little line icons next to every bullet point are everywhere in AI-generated decks. Swap them for your own photos, real screenshots, or simple shapes that support the content instead of just decorating it.
Break the centered-everything habit. AI decks tend to center everything by default: text, images, headlines. Real design has variety. Move text off to one side, let an image bleed to the edge of the slide, and change up the layout from slide to slide so it doesn’t feel like a template on repeat.
Cut the text down. AI tools tend to write in full sentences where a short phrase would land better. Aim for 6-8 words per line on screen. If your audience needs more detail, that’s what your narration or speaker notes are for, not a wall of bullet points.
Prompt It Better From the Start
You can save yourself a lot of the fixing above by being more specific with your prompts in the first place. A few small changes to how you ask make a real difference in what you get back:
- Name your brand colors and fonts directly, instead of asking for something vague like “make it professional.” Give the tool the actual hex codes and font names if you have them.
- Ask for short phrases instead of sentences. Something like “write each bullet as 4-6 words max” gets you closer to a usable slide than leaving it open-ended.
- Ask for layout variety. Try a prompt like “don’t center every slide, alternate between left-aligned text and full-bleed image layouts” to break up the sameness.
- Skip the icon requests. Instead of asking for stock icons, ask for simple geometric shapes, or just leave space where you can drop in your own image later (or describe specific images).
- Feed it an example. If you have a slide you like the look of, upload it and say “match this layout style.”
The AI Gets You 70% There. You Bring the Rest.
Think of an AI-generated deck the way you’d think of a first draft from a junior designer: a solid starting point that saves you real time, but not something you’d hand a client or present to your team without a complete review of it first.
The AI is great at structure, speed, and getting words on a page. The part that makes a deck actually feel like your brand, the fonts, the colors, the little layout choices that show someone paid attention, still needs a human hand. That’s the 30% worth spending your time on.
Next time you generate a deck with AI, try treating it like a rough draft instead of a finished product. A few focused edits are usually all it takes to turn “obviously AI” into “obviously you.”
