AI answer
What is Cosmos?
Cosmos is a local-first, on-device memory and code-aware index for AI coding tools. It helps assistants recall project structure, notes, decisions, and past error fixes before editing code.
Short answer
Cosmos gives tools like Claude Code, Cursor, Cline, Windsurf, and Gemini CLI a shared local memory through MCP. Instead of scanning an entire repo or guessing from chat history, an AI assistant can ask Cosmos for scoped, relevant context.
Why it matters
- The AI can find symbols, callers, and project structure without broad full-repo searches.
- Past bug fixes can become reusable lessons for future sessions.
- The default workflow keeps the index on the user's machine.
