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

Napkin AI

Napkin is a quick way for writers, teachers and consultants to add a clear diagram to a slide or post without opening a design tool. Designers who need pixel-level layout control or long, data-heavy charts will outgrow it.

Pros

  • Works from existing text instead of prompts
  • Every generated element stays editable
  • Exports to PPT and SVG on paid plans, PNG and PDF on Free
  • Free weekly credits cover light use

Cons

  • Free visuals carry Napkin branding
  • Credits scale with words selected, so long passages burn through them
  • No student or non-profit discounts
