AI memory under human control.
Mnemosyne OS is a desktop app for Windows, macOS and Linux. It turns your files and conversations into a memory that any AI model you connect can draw on. You decide what enters, what moves and what leaves. Your vaults live on your own computer.

| MnemoClio | The history of every country on one timeline you can move. |
| MnemoClima | El Niño, the ocean and disasters on one map and one timeline. |
