AI Architect

Ask your AI collaborator to design an auth flow, optimize for scale, or find single points of failure. It builds directly on the canvas — with a cursor you can watch.

Real-time collaboration

See teammates' cursors live. Share canvases with edit or view-only access. Every change syncs instantly — no refreshing, no conflicts.

Load simulation

Run load simulations at 100 RPS to 50K RPS. See latency, cost, uptime, and SPOF warnings — visualised live across all nodes.
