TL;DR
Pick Wonderslide for a quick, low-cost refresh — and choose its “Preserve exact structure” mode if your numbers matter, because its default “Improve and refine” mode dropped most figures on our data-heavy slides. Pick BetterPPT for a client, investor or board deck where every slide should look individually designed and every figure must stay.

BetterPPT

Which one should you use?
Choose BetterPPT if…
The deck is for clients, investors or leadership, the numbers must stay exactly as written, and your photos need work.
Choose Wonderslide if…
You want a fresh look for a few dollars and a few minutes, you're happy to check a watermarked preview first, and you'll pick “Preserve exact structure” when figures matter.
Why the results look different
Wonderslide applies one visual style across the deck and fills it with cards and illustrations, which is why it's fast and cheap; in its default mode it also condenses your text. BetterPPT designs each slide as a full composition around your content and photos, then rebuilds it as an editable PowerPoint — slower and more expensive, but nothing in your source has to give way to the layout.
Wonderslide vs. BetterPPT — questions people ask
Does Wonderslide keep my numbers?
In its “Preserve exact structure” mode, yes. In its default “Improve and refine” mode, our test slide lost most of its figures — 11% of revenue, 1,200+ engineers, 800+ patents, 6 R&D centers and 34% fewer defects — and the About Us slide lost 18,000+ employees and USD 4.2B revenue.
Is Wonderslide cheaper than BetterPPT?
Yes, by a lot: $4.99 per deck versus $39 for up to 30 slides. BetterPPT is priced against hiring a presentation designer rather than against other AI tools.
Does Wonderslide give you an editable PowerPoint?
On its paid options, yes (editable PPTX plus PDF). The free download is a watermarked PDF. BetterPPT includes an editable .pptx with every deck.
