Chat with Claude to brainstorm and architect ideas on an infinite canvas. Unlike regular AI chat, Claude directly creates, connects, and organizes nodes on your diagram in real-time — not just text responses. Describe a SaaS architecture, product launch plan, or investor pitch, and watch it take shape visually. Refine through conversation: restructure, add detail, explore alternatives. Multiple conversation threads per project. Auto-layout. Dark mode. Free to start, Pro for $20/mo.
I built Workbench because I kept switching between AI chat and Excalidraw while brainstorming typing ideas in one place, then manually recreating them in another visual software that I prefer.
Workbench combines both: you chat with Claude and it directly manipulates an infinite canvas, creating nodes, drawing connections, and auto-organizing layouts in real-time.
It's built with React 19, Elysia on Bun, and the Vercel AI SDK streaming Claude Sonnet 4.5. The canvas is powered by React Flow.
Would love your feedback, what kinds of thinking would you use this for?
