TaglineAn 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.OpenAI's image model. Built into ChatGPT Plus.AI search done right. Cited answers, not chat theater.Commercially safe image gen, deeply integrated with Photoshop.

PricingFree (MIT open source)Included with ChatGPT Plus $20/moFree + $20/mo ProFree + included with Creative Cloud
Best forDevelopers working in large or unfamiliar codebases who want their AI coding agent to stop making confident, structurally blind edits — especially Claude Code power users.ChatGPT Plus users who want images without paying extra.Replacing Google for any question where you want a cited answer in seconds.Anyone in Creative Cloud. Brands that need copyright clarity.
Strengths
  • Pre-computes a full dependency graph (functions, imports, class inheritance, execution flows) via Tree-sitter ASTs — agents query structure, they don't guess at it
  • Zero-server, privacy-first: CLI runs entirely locally with no network calls; browser UI processes code client-side and never uploads it
  • Deepest Claude Code integration on the market: MCP tools + agent skills + PreToolUse/PostToolUse hooks that auto-enrich searches and auto-reindex after commits
  • One global MCP server handles multiple indexed repos — set up once with npx gitnexus setup and forget it
  • detect_impact and generate_map MCP prompts give pre-commit blast-radius analysis and auto-generated Mermaid architecture docs
  • Excellent prompt understanding
  • Built into ChatGPT — no extra subscription
  • Good at composition + concepts
  • Sources every claim
  • Fast, current answers
  • Pro Search runs multi-step research
  • Spaces for persistent context
  • Trained on licensed content — commercially safe
  • Generative Fill in Photoshop is incredible
  • Native to Adobe ecosystem
Weaknesses
  • Browser-side RAG has hard ceilings: WASM heap limits constrain embedding model quality compared to server-side tools; monorepos or repos >50k files hit practical walls
  • Community-built and not officially maintained — velocity and long-term support depend on contributor goodwill
  • Claude Code gets the full integration experience; other editors (Windsurf, Cursor) get progressively less — value is uneven depending on your editor
  • Aesthetic ceiling below Midjourney + Ideogram
  • Text rendering worse than Ideogram
  • No fine control
  • Not a general chatbot
  • Answers can be shallow on complex topics
  • Aesthetic ceiling below Midjourney
  • Tied to Adobe subscription
Kai's verdictGitNexus 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.)B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier inside Photoshop (Generative Fill). B-tier standalone.
