COSMOS
A memory layer that lives at your account instead of inside any one assistant. The same graph backs Blueno, WaxFeed, PolarityGPS, and any MCP-capable client you connect.
The gap
Cosmos is a knowledge graph for the things you tell agents. Connect any MCP-capable client (Claude Code, Cursor, Codex, Zed) plus your existing knowledge sources (Notion, Obsidian, your ChatGPT export, your Claude memory export). All of them read and write to the same place at your account, and that account is portable as a single `.polarity` file you own.
The backend is open source. The MCP gateway ships as `@polarity-lab/cosmos-mcp` on npm, so any agent that speaks MCP can connect with one config line. The lab runs the hosted instance at cosmos.polarity-lab.com, and the same code runs anywhere you want to host your own.
