Introduction
Welcome to DrawGPT — the fastest AI Diagram Generator and Diagram-as-Code platform. Create sequence diagrams, ERDs, cloud architectures, and flowcharts from plain English.

DrawGPT is a next-generation AI Diagram Generator that turns natural language and simple code into professional technical visuals. Powered by LLMs and a real-time rendering engine, it lets you go from idea to diagram in seconds — no dragging, no fiddling.

Diagram-as-Code means defining your visuals in plain text instead of dragging boxes around in a GUI. Think of it like Markdown for diagrams:
| Feature | Traditional Tools | Diagram-as-Code |
|---|---|---|
| Speed | Drag & drop each element | Type it in seconds |
| Version Control | Screenshots in Confluence | Text diffs in Git |
| AI-Compatible | Manual only | LLMs can write it natively |
| Consistency | Ad-hoc styling | Deterministic layout engine |
| Collaboration | Email PNGs around | Share a text file |
Why text beats drag-and-drop
DrawGPT's DSL is designed to be readable by humans and writable by AI. The layout engine handles positioning, spacing, and routing automatically — so you focus on what to draw, not where to place it.
AI Assistant
Not sure how to write the syntax? The integrated AI chat understands all four diagram types natively.
You say: "Show me a microservice architecture with an API Gateway, three services, and a shared Redis cache."
DrawGPT writes the code and renders it on your canvas — ready to edit, export, or extend.
The AI also supports:
- Editing existing diagrams — "Add a Database node connected to the User Service"
- Explaining syntax — "What does
activatedo in a sequence diagram?" - Converting between types — "Turn this flowchart into a sequence diagram"
