What our research says

Gamma

The tool that genuinely displaced PowerPoint for a lot of people, and it is profitable enough not to need your money — but credits, not seats, decide how much a plan is actually worth.

Pros

  • Layout and image choice happen without picking a template first
  • One document publishes as a deck, a doc or a live web page
  • Plus at $8/user/month already removes the Gamma badge
  • Profitable at over $100M ARR, so the vendor is not a runway risk

Cons

  • Credit accounting is opaque — a premium image can cost up to 125 credits
  • API keys are locked to Pro and above
  • The free plan's 400 signup credits do not go far on image-rich decks
  • Export fidelity to PowerPoint degrades on complex layouts

AI Presentation Maker by SketchBubble

This is a fast way to get a presentable deck out of a rough topic or an existing PDF, backed by a company that has spent over a decade building slide templates, which shows in the output's visual polish compared to some AI deck generators. The free tier is real but capped tightly enough that regular use pushes you to a paid plan quickly.

Pros

  • Can generate a deck directly from an uploaded PDF, not just a text prompt
  • Exports to both PPTX and Google Slides for full editing
  • Backed by a library of tens of thousands of pre-built templates for design quality
  • Free tier exists with no-cost AI credits to try before paying

Cons

  • Free plan is capped at 10 downloads and 500 AI credits a month
  • Published pricing was inconsistent across sources we checked ($14.95 vs $24.95/month)
  • AI product is new (launched 2025) compared to the company's decade of template work
