| Kai's verdict | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. | GitNexus solves a real and underappreciated problem: AI coding agents are syntactically fluent but architecturally blind, and plugging a pre-computed knowledge graph into the MCP layer is the right fix. 28k GitHub stars in days suggests the pain is widely felt — just go in knowing it's a community project, not a polished product. (Verdict pending Phi's full review.) | A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs. | S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds. |
