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

SlideFlow

SlideFlow does one thing — turn text into a PowerPoint deck — and prices it by the presentation instead of by the month, which suits someone who needs a deck twice a year rather than every week. Slide counts are capped low even on paid tiers, and the free plan's output disappears after 72 hours.

Pros

  • No subscription required — pay only for the presentations generated
  • Exports support 85+ languages
  • Free tier lets you try the output before paying

Cons

  • Slide count is capped at 9 even on paid plans
  • Free-tier presentations are deleted after 72 hours
  • Company identity and location are not disclosed

Which one fits

  • Users who want AI layout but expect to keep editing afterwards

Choose SlideFlow if you need

  • Someone who needs one or two decks and doesn't want a subscription
  • Quick first-draft slides to hand-finish elsewhere
