Enterprise scheduling optimization APIs and a proven constraint solver
Ready-made REST APIs for field service routing, employee shift scheduling, pickup and delivery routing, and task scheduling, each tuned to the constraints those problems actually involve.
Describe your scheduling problem in natural language and Timefold generates an API that solves it, shortening the path from idea to a working optimizer.
Send JSON in and get JSON out through a technology-agnostic, stateless API, so you can integrate without rewriting your architecture or adopting a new platform.
Inspect constraint scores, compare scenarios, and run simulations so planners and stakeholders can understand and trust the decisions the solver makes.

The collaborative whiteboard built for product builders
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.
