What is MemOS?

A self-hosted notes & knowledge management tool. Your data lives on your server — no vendor lock-in, no risk of provider shutdown.

The biggest strength is no vendor lock-in — markdown/JSON data, easy to migrate between tools.

Best for researchers, devs, product people — anyone wanting a portable second brain across devices.
