What it is
Gamma is a San Francisco startup that builds presentations, documents, simple websites, social posts and graphics from a prompt, outline or uploaded file. You describe what you need, it drafts the structure, writes the text, picks a layout and adds images, and you then edit card by card. It imports PDF and PowerPoint files and exports to PDF, PowerPoint, PNG and Google Slides.
It uses a mix of AI models, including Claude, ChatGPT, Gemini, Flux, Recraft, Ideogram, Luma and Leonardo, with better image and video models on higher plans. Pro adds custom branding, analytics, up to 10 custom domains and API access. Business, at $40 per member per month billed annually, adds SSO, 10,000 credits per member and a training opt-out that members cannot change; Enterprise adds SCIM and audit logs.
According to its About page, Gamma has 100 million users, $100 million in annual recurring revenue and a $2.1 billion valuation, after a $68 million round reported in November 2025. Unused credits roll over up to twice the monthly amount. On individual plans, Gamma may use your content to train its AI features unless you opt out.
Our review
Gamma is the AI presentation tool most people end up recommending, and the reason is the first draft. A prompt or a long document becomes a structured, designed deck with card layouts that adapt to the content instead of fixed slide templates, and its developer docs put a typical generation at one to three minutes. Reviewers and users on Reddit say it saves the most time on first drafts, internal updates and pitch outlines.
The card format is also the catch. A Gamma deck is really a web page, so it shares as a link with analytics or turns into a document or simple site, which PowerPoint and Google Slides cannot match. It also means PowerPoint and Google Slides exports are translations, and users report lost formatting. Teams bound to strict corporate templates will find Gamma fights them, and Pitch or Beautiful.ai give finer layout control.
Credits govern everything. Per the API docs, cards cost 1 to 3 credits each and images 2 to 125 depending on the model tier, so a 20-card deck with a premium image on every card can use roughly 700 to 1,560 of Pro's 4,000 monthly credits. Unused credits roll over up to twice the monthly amount, and the free plan's 400 never refill.
For engineers, Gamma is more programmable than most rivals. The REST API, on Pro and above, generates decks from text and charges the same credits as the app, while an MCP server and the Claude, ChatGPT and Slack connectors work on every plan, including Free. The help centre cites a limit of 50 generations an hour, enough for a sales team but not for bulk generation.
The data question splits by plan. On Free, Plus, Pro and Ultra, Gamma may train its AI features on your content unless you opt out under Settings, Data Controls; Business locks training off for the whole workspace and adds SSO, while SCIM and audit logs are Enterprise only. For a consultancy putting client material into decks, that makes Business at $40 a member, not Pro at $18, the real entry price.
Where it earns its place
A management consultant producing three client decks a week
Turn interview notes and a findings document into a first-draft deck
Uploads the document, generates a draft, then rewrites the AI text and fixes the charts. Client confidentiality points to Business at $40 a month billed annually, for SSO and a locked training opt-out; on Pro, training stays on unless switched off.
A developer at a sales-enablement startup
Generate a tailored pitch deck for each new CRM opportunity
Calls the generations API from a webhook and polls for the result, usually ready in one to three minutes. A 10-card deck with standard images costs about 30 to 180 credits, so Ultra's 20,000 a month covers roughly 110 to 660 decks; a 429 response means the hourly limit was hit.
A first-time founder preparing a seed pitch
Get a credible 12-slide deck together in an afternoon
Plus at $9 a month (billed yearly) gives 1,000 credits and removes Gamma branding. If investors expect a .pptx, the exported file needs a pass in PowerPoint before it goes out.
