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

SlideNotes

A narrow tool that does one conversion — deck to bullet notes — and prices it low enough to be an impulse purchase, including a $49.99 lifetime option that beats ten months of subscription. That narrowness is also the limit: two file formats, no integrations, and a small solo operation behind it with no company details published.

Pros

  • Accepts both .pptx and .pdf and returns structured bulleted notes
  • $4.99/month, $29.99/year or $49.99 once for lifetime access
  • Free tier lets you test on real files before paying
  • Terms and privacy policy published in full, dated from January 2024

Cons

  • Only two supported file formats; no Slides or Keynote import
  • No company entity, address or country named — email is the only contact
  • No API, integrations or bulk processing
