Four parts of one open-source codebase.
Documents are connected, parsed and indexed (Knowledge). Agents answer over them with citations and call tools (Agents). Multi-step jobs run node by node with human approval where a step is uncertain (Workflows). Guardrails, the audit log and SSO/SCIM/RBAC apply across all of it (Governance).
Knowledge
30+ file formats, connectors for Google Drive, SharePoint, Confluence and S3, OCR for scanned PDFs, chunk management per source. Docs: sources
pdf · docx · xlsx · pptx · md · html · drive · sharepoint · confluence · s3
Agents
Classic, Agentic, Research and Workflow agent types; scheduled runs; tools over MCP and JSON-schema APIs. Docs: agents
classic · agentic · research · workflow · cron · mcp
Workflows
Drag AI Agent, Condition, Code and End nodes onto a canvas; every execution keeps its run history. Docs: workflows
agent · condition · code · end · run history
Governance
7 guardrail checks that flag, redact or block; human approval for answers and tool calls; append-only audit log; OIDC SSO, SCIM 2.0 and RBAC via Admin. Docs: guardrails
