| Kai's verdict | B-tier. Still early. Manus is more flexible for less money. | 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. Best for cinematic image-to-video. Pair with Runway for coverage. | A-tier. Best free agentic option in VS Code. Use with Claude for best results. |
