What it does

• Visual and AI-assisted authoring. Build and inspect workflow graphs on the canvas, generate or revise them through the AI Assistant using text or voice, and reuse templates.
• Agents and deterministic logic. Combine LLM and Agent nodes with conditions, switches, loops, merges, data transformations, and sub-workflow calls. Use expressions in supported node fields.
• Multi-agent orchestration. Give an orchestrator named sub-agents and sub-workflows to call. Independent sub-agent calls can execute concurrently.
• Knowledge and persistent memory. Retrieve documents through RAG using Qdrant or PostgreSQL with pgvector. Enable per-agent knowledge graphs to retain facts across runs, with configurable sharing between agents.
• Tools and integrations. Connect communication services, developer tools, productivity apps, databases, queues, and storage through built-in nodes, HTTP APIs, and MCP. Use MCP Call nodes for deterministic tool invocation.
