Compare
Cosmos vs generic RAG.
Generic RAG retrieves chunks. Cosmos focuses on local-first developer memory: code symbols, project lessons, decisions, and scoped MCP tools.
The difference
Cosmos is not just a vector search box. It combines local indexing, structured code context, saved notes, and error+fix lessons for AI coding workflows.
Why that matters
- Code context has structure: symbols, callers, files, and runtime errors.
- Developer memory has history: decisions, regressions, and fixes.
- AI clients need small, trustworthy context more than unlimited retrieval.
