The visual layer for coding agents
Draw diagrams visually.
Your agent reads it as text.
You think best in pictures; coding agents think best in text. Sketch system architecture, flowcharts, state machines, ER and class diagrams in your browser — then export an AI-optimized version your agent reads precisely. One artifact, two audiences.

The gap we close
Humans operate visually. Agents operate on text.
Drawing is the fastest way to think through structure — boxes, arrows, states, relationships. But a coding agent can’t see your canvas; it reads text, and it reads it precisely. Draw the way that’s natural for you, then export the same diagram into an AI-native format the agent understands exactly — no re-explaining the architecture in every prompt.
For you
A picture to think in
Lay out the system by hand. Pan, connect, rearrange — reason about the shape of the thing the way your brain actually works.
The export
One click, two forms
The same diagram becomes structured text — nodes, edges, groups, and relationships — tuned for how an LLM parses it.
For your agent
Text it reads precisely
Hand the agent an exact, structured description of your architecture instead of a paragraph of prose it has to interpret.
One canvas, every notation
Almost every diagram software needs.
From cloud architecture to class hierarchies — draw it here, export it for your agent, keep it as a first-class document when you sign in.

How it works
Draw it. Export it. Hand it to your agent.
Draw it visually
Open the editor in your browser — no account needed. Pick a diagram type and lay out boxes, arrows, and states by hand.
Export to AI-native text
Turn the drawing into structured text your coding agent reads exactly. Give it the architecture instead of describing it in prose.
Hand it to your agent
Paste it into your prompt, or sign in to keep it in Windy — versioned, and read by your agents over a project-scoped MCP endpoint.
Free tool · optional platform
