FAQ

Common questions

Is ArchDraw free?
Yes — free during beta. Guests get 3 generations/hour, signed-in users 10/day. Paid plans will come with a launch discount for early users.
Do I need an account?
No. Generate and explore without signing up. Sign in only to save canvases, share links, and export SVGs.
How is this different from draw.io / Lucidchart?
We generate the diagram for you from a prompt, Mermaid, or GitHub repo, with validated tiers and auto-layout. You edit, not draw from scratch.
Can I import Mermaid?
Yes. Paste Mermaid (graph LR/TD with subgraphs) — it round-trips via the same pipeline (React Flow → Mermaid → Dagre → positions).
What is the MCP server?
A local stdio JSON-RPC server that lets Claude/Cursor call tools like generate-diagram, update-diagram, fix-layout directly on your canvas.
Is my data private?
Prompts are processed per-session, not stored or used for training. Canvases are localStorage for guests, Supabase for signed-in users.
