Two months ago I tried the MCP service of a domestic patent database vendor. Their AI offering seemed to have been out for a while, the docs looked complete and the feature coverage was broad, so I asked them for a trial. In practice the product is still rough, and it is not cheap either — in the end we simply had the agent drive a browser to reach the AI.

Recently, I spent several days deeply experiencing multiple AI Agent products, from WorkBoddy, OpenClaw, LobeHub, DeerFlow2, LirbeChat, DingTalk Wukong to OpenCode, trying almost every tool I could find. Everyone has different needs, but my main focus is on open source and self‑deployable, feature completeness, and practical usability. Below is my personal comparison from a practical usage perspective.
