OVERVIEW
Describe a system in natural language and watch an autonomous AI architect draw it — nodes, edges, labels — on a canvas your whole team is editing live.
Ghost-AI is an enterprise-grade collaborative whiteboard built on CRDTs: every shape, edge and label lives in Liveblocks LiveMaps, so simultaneous edits from multiple collaborators merge without conflicts. Live cursors, presence avatars and an in-workspace chat feed make it feel like one shared room.
The AI architect is a Gemini 2.5 Flash agent wielding eight discrete tools — addNode, moveNode, resizeNode, updateNodeData, deleteNode, addEdge, deleteEdge, finalizeDesign — executed serverlessly through Trigger.dev so long-running generations never hit timeouts. Canvas state auto-saves on a two-second debounce to Vercel Blob, indexed in PostgreSQL via Prisma.
Finished designs compile into multi-page Markdown specifications — overview, architecture, data flow, technology choices — turning a sketch session into technical documentation automatically. Auth and multi-tenant workspaces run on Clerk with room-level isolation.
OUTCOMES
The diagram isn't documentation of the design. The diagram is the design.
