EverOS

What it does

Stores conversations, files and agent trajectories as plain Markdown, then keeps local SQLite and LanceDB indexes alongside for fast retrieval — so the memory layer travels between coding assistants, apps and devices, and you can inspect or hand-edit what the agent believes. Readability cuts both ways: anyone with access to the folder reads everything, so decide placement and a deletion policy up front. Apache-2.0.

EverOS FAQ

Is EverOS free?

Yes. It runs on your own machine, so there is no usage-based cost either.

Do I need to install anything or write code to use EverOS?

It connects to an MCP-capable AI app such as Claude. It does not run on its own.

Does EverOS work on a phone?

No. It needs a computer.

Can I use EverOS commercially?

The licence is Apache-2.0, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
