Cosmos vs Cursor memory.
Cursor memory is part of one editor. Cosmos is a local memory and code-aware index that can serve multiple MCP-aware AI coding tools.
Best way to think about it
Cursor is where you may edit. Cosmos is where durable project memory can live beside the editor, so the same context can help Claude Code, Cursor, Cline, Windsurf, and Gemini CLI.
Choose Cosmos when
- You switch between more than one AI coding client.
- You want local project lessons to outlive a single editor chat.
- You want a separate MCP memory layer that does not depend on one IDE.
