Prose in.
Structure out.

ChartCraft reads plain English and emits flowcharts, ERDs, BPMN, sequence, class, and state machines — laid out, labelled, and ready to export. Not a drawing app. A compiler.

Six grammars,
one canvas.

Every diagram family has its own syntax — entities, actors, states, gateways. ChartCraft speaks all six natively and picks the right one from the way you describe the problem. You can override at any time.

01
Flowchart
Decisions, branches, and processes. Great for architecture and system maps.
FLOW · ~2KB/min
02
Sequence
Actors talking over time. Perfect for APIs, auth flows, and protocols.
SEQ · time-ordered
03
ERD
Entities, keys, cardinalities. Drop SQL hints and get a clean schema.
ERD · crow's-foot
04
BPMN
Events, tasks, gateways. Business-grade notation when stakes are high.
BPMN 2.0 · lane-ready
05
Class
Types, methods, inheritance. UML without the XML headache.
UML · typed
06
State
Machines, transitions, guards. Model anything with a lifecycle.
FSM · guarded
