Software diagrams
for developers, teams, and agents.

Draw your systems in the notations you love. Work with agents to create, analyze, refine, and refactor — all in one shared visual workspace.

Built from the ground up for AI Agents

See and refactor your architecture with a prompt.

Connect Claude Code / Codex via MCP and your agentic coding assistants see and understand your models. Understand what the AI is building, ask questions and get beautiful diagrams back explaining your system.

Generated with one prompt: DrawMode showing a layer diagram of how it is built: access, the canvas engine, the products, the shared cores and drawcore, with live collaboration cutting across them
DrawMode showing its own architecture: a UML package diagram — drawmode over mindmapcore, widgetcore, aicore and vectorcore, all resting on drawcore — beside the domain model of Project, Diagram, Shape, Node and Link
An exceptional diagram editor

Draw to understand, document, and explain.

Create beautiful architecture, behavior, data, and UI diagrams in the notations you know. Hold Shift for the right action at the right time. DrawMode derives the model as you work.
