What Makes Yao Different?

| Traditional AI Assistants | Yao Autonomous Agents | | ----------------------------- | ------------------------------------- | | Entry point: Chatbox | Entry point: Email, Events, Schedules | | Passive: You ask, they answer | Proactive: They work autonomously | | Role: Tool | Role: Team member |

The entry point is not a chatbox — it's email, events, and scheduled tasks.

Features

Autonomous Agent Framework

Build agents that work like real team members:

• Three Trigger Modes — Clock (scheduled), Human (email/message), Event (webhook/database)
• Six-Phase Execution — Inspiration → Goals → Tasks → Run → Deliver → Learn
• Multi-Agent Orchestration — Agents delegate, collaborate, and compose dynamically
• Continuous Learning — Agents accumulate experience in private knowledge bases

Native MCP Support

Integrate tools without writing adapters:

• Process Transport — Map Yao processes directly to MCP tools
• External Servers — Connect via SSE or STDIO
• Schema Mapping — Declarative input/output schemas

Built-in GraphRAG

• Vector Search — Embeddings with OpenAI/FastEmbed
• Knowledge Graph — Entity-relationship retrieval
• Hybrid Search — Combine vector similarity with graph traversal

Full-Stack Runtime

Everything in a single executable:

• All-in-One — Data, API, Agent, UI in one engine
• TypeScript Support — Built-in V8 engine
• Single Binary — No Node.js, Python, or containers required
• Edge-Ready — Runs on ARM64/x64 devices
