|---|---|---|---|---|
| Tagline | AI search done right. Cited answers, not chat theater. | Wire Cursor's full coding-agent runtime into your own apps, scripts, and CI/CD pipelines with a few lines of TypeScript. | An open-source, MCP-native knowledge graph engine that gives AI coding agents (Cursor, Claude Code, Windsurf) genuine structural awareness of your codebase before they touch a single line. | Mac launcher + AI. Command-bar genius. |

| Pricing | Free + $20/mo Pro | Token-based; requires Cursor plan (Pro from $20/mo). Composer 2 at $0.50/$2.50 per M tokens (in/out); fast variant $1.50/$7.50 per M tokens. | Free (MIT open source) | Free (app) + $10/mo AI |
| Best for | Replacing Google for any question where you want a cited answer in seconds. | Engineering teams who already use Cursor and want to embed its coding-agent runtime into CI/CD pipelines, backend services, or internal developer tools without building agent infrastructure from scratch. | Developers working in large or unfamiliar codebases who want their AI coding agent to stop making confident, structurally blind edits — especially Claude Code power users. | Power users on Mac who type a lot. |

| Kai's verdict | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | If your team is already in the Cursor ecosystem, this is a genuinely compelling way to turn ad-hoc AI coding sessions into durable, automated workflows — but the beta label and Cursor's history with opaque pricing mean you'll want to set hard budget guardrails before going to production. (Verdict pending Phi's full review.) | 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.) | S-tier if you're on Mac. The fastest way to get AI answers without context-switching. |
