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.
Turn policies into AI-enforced workflows you can prove
Centralise policies and SOPs with version control and governance mapped to frameworks such as ISO 9001, SOC 2, SOX and FDA requirements.
Turn policies into structured workflows with owners, due dates, conditional logic and approvals, so every step is followed rather than assumed.
Monitors regulatory changes, automates the associated work and flags risks and gaps before they turn into audit findings.
Records who completed each step and when, with required file uploads, form entries and approvals attached to the task.
