Open-source, human-in-the-loop workflow layer for on-premise AI
AI reads, extracts and drafts inside a workflow, but a named person reviews and approves each critical step so there is an audit trail by design.
Build processes with triggers, conditions, forms, tasks and approvals without writing code, and refine them as the process evolves.
Ready-made workflows for HR, sales, finance, procurement, IT, healthcare and more, usable as-is or as a starting point.
Apache 2.0 core with public code, so security teams can audit it and organisations can deploy on-premise or in a private cloud.
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.
Industry standard collaborative whiteboarding with massive template libraries, but less streamlined for rapid AI diagram generation.
