Compare Editions of Astah
AI-Assisted Modeling in Astah
AI Chat Copilot and the MCP server are included in all four editions, starting with version 11. AI Chat Copilot connects to an AI service you choose, using your own API key for OpenAI, Claude, Gemini, or an OpenAI-compatible service. The MCP server needs no API key in Astah: AI clients such as Claude Code connect to your models and use their own account. Azure OpenAI is available for AI Chat Copilot in Astah Professional and Astah UML version 12 and later. To see how AI clients such as Claude Code work with your models through the MCP server, see Use AI Clients with Real UML Models: Astah’s MCP Server.
