Independent review. IonBin has no partnership with Gamma and was not paid for this page. Our evaluation is our own, based on public documentation and our research. Product names are trademarks of their owners and are used for identification only. How disclosure works.
Generates presentations, documents and web pages from a prompt, outline or imported file. Its hosted MCP server, on all Gamma plans, lets an AI assistant create, edit and export gammas; generations use credits.
Gamma lists Free ($0; 400 credits at signup, up to 10 slides per prompt), Plus ($9/seat/month billed annually or $12 monthly; 1,000 credits a month), Pro ($18 annually or $25 monthly; 4,000 credits, API access), Ultra ($90 annually or $100 monthly; 20,000 credits), Business ($40/seat/month annually) and custom Enterprise. Prices may be subject to tax depending on location. Checked 2026-10-17. source ↗
The MCP server can create, browse, search, read and export gammas, and read comments and analytics. Each edit changes one page and cannot add pages. Plan limits on cards, image models and credits apply to every request. It also powers Gamma's apps for Claude, ChatGPT and Slack. source ↗
How Gamma connects to each AI platform: native connector or MCP, API through code the agent writes, browser control, or file upload.
| Platform | MCP / connector | API (agent-written code) | Browser | Upload / export |
|---|---|---|---|---|
| Claude (incl. Claude Code) | Confirmed Gamma connectors in Claude and ChatGPT Gamma docs ↗Claude (incl. Claude Code) MCP docs ↗ | Confirmed Claude (incl. Claude Code) can run code; Gamma publishes an API. Gamma API ↗Claude (incl.

Claude Code) browser docs ↗ | Confirmed Export from Gamma, then works on the files in your project; chat accepts attachments Claude (incl. Claude Code) docs ↗ |
| OpenAI Codex | Not documented Gamma has an official MCP server and OpenAI Codex supports MCP, but Gamma's docs don't name this pairing. Auth setup may differ.

Gamma's docs also name: ChatGPT.
Confirmed means both the tool's and the platform's official docs describe that route (links in the cell); IonBin has not tested every pairing. Not documented means it may work, but no official docs describe that route end to end. Checked Oct 17, 2026.
| Level | Status | Detail / source |

Recorded Oct 17, 2026. Setup and plan limits vary; check the vendor's docs. How levels are assigned.
Via its official MCP server, from MCP-capable platforms such as ChatGPT, Claude, Gemini (Google), Google Antigravity, OpenAI Codex.
Via its API, through automation hubs: Gumloop, Make, n8n, Zapier.
No long-form review yet. Verdict is based on research, not hands-on testing.
Template-based design for social posts, decks and marketing assets. Its MCP server and AI connector let assistants create, edit, search and export designs; brand kits and Brand Templates need a paid plan.
