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

Plus AI

The one thing it does that standalone deck generators cannot is leave you with an ordinary Slides or PowerPoint file that colleagues can open and edit without an account. That alone decides it for most corporate users. The absence of any free tier means you evaluate on a carded trial or not at all.

Pros

  • Native add-on for both Google Slides and PowerPoint, output stays in the native format
  • Generates from a prompt, a pasted document or an uploaded PDF
  • Slide-level rewriting, reformatting, translation and image generation after the first draft
  • Separate market-research report generator from a company or industry name
  • Presentations API, agent API and MCP server for programmatic use

Cons

  • No free tier at all; the 7-day trial requires a card
  • Credit-metered, so heavy generation runs out before the month does
  • Team tier is per user, so cost scales linearly
  • Output still needs a manual design pass for anything client-facing

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 Plus AI if you need

  • Teams locked into Google Slides or PowerPoint who cannot hand round a proprietary deck format
  • Turning an existing document or PDF into a first-draft deck
  • Slide-level editing tasks like rewriting, reformatting and translating
