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 $9 per seat per 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

Twistly

The cheapest credible deck generator we have priced, and the only one here that lives inside PowerPoint rather than exporting to it — which matters if your organisation runs on .pptx and a corporate template. Slide caps are the limiting factor: 10 free, 35 on Pro, so long training decks need a different tool.

Pros

  • Runs as a Microsoft 365 add-in in desktop PowerPoint and PowerPoint on the web
  • Accepts PDF, Word and raw text as input, not just a prompt
  • Free tier is genuinely usable at up to 10 slides with the badge removed
  • Pro is $7/month, well under the category norm
  • Translator, AI image generation and custom brand templates included

Cons

  • Hard slide caps per tier (10 free, 35 Pro)
  • No API
  • No legal entity, address or country published
  • Live prices are injected by script and invisible to anything but a browser

Which one fits

Choose Gamma if you need

  • Anyone who needs a presentable deck out of rough notes in minutes
  • Teams publishing one-page sites and documents without a website tool
  • Users who want AI layout but expect to keep editing afterwards

Choose Twistly if you need

  • Students and teachers turning notes or a PDF into slides
  • Sales and HR teams tied to a PowerPoint template
  • Anyone who wants to stay inside Office rather than a web editor
