DiagramGPT

DiagramGPT, made by Eraser Labs, Inc., is an AI-powered tool that generates polished diagrams from text prompts in seconds, supporting multiple diagram types including flowcharts, entity relationship diagrams, cloud architecture diagrams, sequence diagrams, and BPMN diagrams. It offers text-to-diagram generation across five-plus diagram types, editable diagrams using diagram-as-code syntax within the broader Eraser platform, and a diagramming API for workflow integration. DiagramGPT includes an MCP (Model Context Protocol) server for agent integration with Claude, Cursor, VS Code, and ChatGPT, plus integrations with development tools like Confluence, Notion, VS Code, and GitHub. Eraser maintains a Slack community and documentation for its broader technical design and documentation platform built for engineering teams. Pricing is freemium: DiagramGPT itself is free to use, while advanced Eraser features require paid Starter, Business, or Enterprise plans; the MCP server is free but subject to plan-based AI credit limits.
