AI flowchart tool

Q: Is the AI flowchart generator free?

Yes. cnvs.app is free with no signup. Your own AI agent (Claude Desktop, Claude Code, or any MCP client) connects to the public MCP endpoint — cnvs.app does not charge for the board.

Q: How is this different from the flowchart maker page?

The flowchart maker page focuses on text-to-flowchart and freehand drawing. This AI flowchart page emphasizes agent-driven diagramming via MCP while still supporting Mermaid text you type yourself.

A free AI flowchart tool on a collaborative whiteboard — type Mermaid flowchart text yourself, or let an MCP agent draw the diagram onto the same live board. No signup, share by URL.

Two ways to get an AI-assisted flowchart

You type, it renders. Write Mermaid flowchart syntax in a diagram node; cnvs.app renders it server-side to SVG on the canvas.
An agent draws. Point Claude or any MCP client at https://cnvs.app/mcp. The agent reads board state and writes flowchart nodes, notes and arrows live beside you.
Humans stay in the loop. Edit freehand, move nodes, and keep chatting with the agent on the same URL — not a one-shot image dump in chat.

How to generate a flowchart with AI

Open a board. Use Start an AI flowchart for a seeded Mermaid example, or open a blank board.
Connect your agent. Add https://cnvs.app/mcp in your MCP client — see the MCP guide.
Ask for a flowchart. Tell the agent the process steps; it writes Mermaid (or structured nodes) onto the board. You refine live.
