Does Cosmos upload my code?

No. Cosmos builds and stores its core code index locally by default. Hosted backup and sync are roadmap services, not required for current Free or Plus usage.

Local-first AI coding memory

Give your AI coding tools a memory that stays on your machine.

Cosmos indexes selected projects and notes on-device, then serves scoped context to AI coding tools through MCP. Your assistant can recall symbols, decisions, and prior fixes without scanning the whole repo again.
