Gamma

Category: AI Image/Design

Decks, sites and social graphics from a prompt, with an MCP server.

Gamma generates presentations, websites with custom domains, social graphics, documents and standalone images from a prompt, an outline or a pasted document. The current engine, Gamma 5, works agentically rather than filling a template, and you steer it with a quality preset. Import comes from PDF and PowerPoint; export goes to PDF, PowerPoint, PNG and Google Slides, so it fits round tools people already use rather than replacing them. Cards reflow responsively instead of breaking like a slide, which is why the output holds up on a phone. Higher tiers add premium image models, custom branding, per-viewer analytics and custom domains, with video models at the top. Pricing is credit-based: classic generations cost one to three credits per card and images from two to 125 depending on the model, while Gamma 5 agent jobs are priced by the work done. There are iOS and Android apps, and the company publishes worked credit examples so you can estimate before committing.

Our verdict

The best-value tool in its category and, for this audience, the API and MCP story is what pushes it ahead. A hosted MCP server with OAuth is available on every plan including the free one, alongside a public REST API covering generation, editing, export and per-viewer analytics, with ChatGPT, Claude and Slack connectors. Very little document tooling is that open. The company is also unusually solid for an AI product: past $100m in revenue, profitable, SOC 2 Type II, with a published trust centre. On the practical side, output quality is genuinely good and the responsive cards mean decks survive being read on a phone. The thing to watch is credit forecasting. Agent pricing is non-deterministic by Gamma's own admission, so the same prompt can cost differently run to run, and the free tier's 400 credits are a one-off rather than monthly. Note too that Gamma 5 does not handle webpages or multi-page documents, which fall back to the classic engine.

Best for: Anyone who makes decks, one-page sites or social graphics regularly and wants a good first draft in a minute, plus teams wiring document generation into an agent workflow.

Pros

  • Hosted MCP server with OAuth on every plan, including free
  • Public REST API covering generation, editing, export and per-viewer analytics
  • Produces websites with custom domains and social graphics, not only decks
  • Exports to PowerPoint, PDF, PNG and Google Slides, so it fits existing workflows
  • Cards reflow responsively, so output holds up on a phone
  • Profitable, past $100m revenue, SOC 2 Type II with a published trust centre

Cons

  • Credit costs are hard to forecast, agent pricing varies run to run by their own admission
  • The free tier's 400 credits are a one-off at signup, not monthly
  • Gamma 5 does not support webpages or multi-page documents, those use the classic engine
  • Analytics and the highest quality setting sit on Pro and above
  • A shared API key draws down the owner's credit balance
