In their own words
Red Arch Knowledge Manager
Red Arch Knowledge Manager is an open-source, self-hostable platform combining organizational knowledge, AI chat, content management, workflows, customer integration, and learning management. Its AI search answers questions from organizational content using semantic and keyword search with passage-level citations. Folders and spaces can have document and folder permissions that also govern search and AI chat. A visual no-code BPMN builder supports form, schedule, event, and inbound-webhook triggers, plus AI steps, approvals, branching, and notifications. Users can create courses from documents, run server-graded quizzes and AI-graded scenarios, issue certificates, and view learner progress dashboards. A versioned REST API, organization-scoped keys, and HMAC-signed webhooks connect other systems. An MCP server lets assistants such as Claude and Cursor build entities, forms, views, reports, and workflows while respecting permissions. Docker and Compose support deployment. The Apache License 2.0 permits commercial use, modification, and redistribution. The listed plan costs nothing with no per-seat pricing.
