Demos

See Qtangl on real planning problems.

Full workflows for buyers. API sandbox for developers. Same ranked-plan output, different depth.

Sandbox the API: send a real /optimize request, see a real ranked plan. Falls back to a static response if the pilot endpoint is offline.

Three planning shapes. One request. — Edit constraints, send a real /optimize call, get back the same JSON your app will see. Read API docs

Amplitude

Pick a planning shape.

Choose a scenario, review the request shape, then call the live pilot endpoint.
