How Mnemosyne OS works, in one page
Mnemosyne OS is a memory that lives on your machine. It reads documents you point it at, keeps them, and uses them to answer your questions.
Vaults, and how to create one
A vault is an isolated memory store. Mnemosyne OS does not keep one large memory: it keeps several, one per domain of your life, and each lives in its…
RAG attention, the slider that decides who answers
Every vault carries a 'RAG attention' slider, from 0 to 100 percent. It sets how much that vault weighs when memory is queried: at 100 it counts fully…
What MAXIMUM protection blocks, and what it does not
Every vault carries a protection level, set in Settings then Vaults. Two matter day to day: NORMAL, the default, and MAXIMUM, for what you do not want…
Watched folders, and the state of each one
A watched folder is a folder on your disk that a vault follows continuously. Mnemosyne OS ingests what is there, then reacts to changes: a modified…
When an answer finds nothing
'I know it is in my memory and it cannot find it' has several very different causes, and they are not fixed the same way.
Plugging in your own model server
Mnemosyne OS can call a model server you own instead of a provider. Any server compatible with the OpenAI API works: vLLM, Ollama, TGI, or an internal…
Image memory (Theia)
Theia is Mnemosyne OS's visual memory. Once it is on, the images in your watched folders are indexed, and a question like…
The Neural Map, your memory seen as a graph
The Neural Map shows your memory as a graph. Each node is a memory, each link joins two memories the engine finds close to each other.
What you can ask me, and how
I answer two kinds of question, and they do not travel the same path. Questions about the product (how something works, where a behaviour is set, why…
Taking notes in class: the lecturer's PDF, photos of the projector and your notes
A lecture leaves three traces: the PDF the lecturer hands out before or after, the photos you take of the projector, and the notes you type in a hurry…
Hand gestures, driving everything with the camera
Mnemosyne OS can follow your hand through the webcam. You move the board, open an app or close a window without touching the mouse.
Keeping an agent conversation in memory
Claude Code and Antigravity write every conversation to your disk. Claude Code deletes its own after 30 days. Ariadne, the Hub app that reads these…
My machines, linking your computers together
My machines links your own computers that run Mnemosyne OS. Once paired, each computer shows the other's agents on its board.
