Everyone is building the intelligence. Mnemosyne builds the relationship — the memory that makes an AI truly know you, across sessions and across time. On your machine. Yours to see.

🌍 Fully multilingual — the OS speaks your language

The entire interface is localized in seven languages — onboarding, settings, chat, the voice assistant, every dialog. Switching language even re-selects the ★ recommended embedding model for it, so retrieval quality follows your language, not just the labels. Open windows pick the change up instantly.

Not another agent-memory library

Mem0, Zep and Letta give agents a memory layer you wire into a cloud stack.

Mnemosyne OS is a personal memory OS that runs on your machine — your data never leaves it, a human governs it, and it scores 77.1% on LongMemEval-M (audit it yourself).

The AI that remembers you — not infrastructure you plug into someone else's.

Where the project lives

Published by XPACEGEMS LLC. These are its official addresses:

Why call it an "OS"?

Not because it has a kernel or drivers — because it does what an OS does: it manages resources on behalf of processes that shouldn't have to manage them themselves. Linux does that for programs (CPU, RAM, disk, network). Mnemosyne does the same thing for AI agents, and the resources are just different:

This isn't a marketing stretch invented for this repo. MemGPT (Packer et al., UC Berkeley, 2023, arXiv:2310.08560) proposed the same "OS for LLMs" analogy in a peer-reviewed paper — virtual context management modeled on OS memory hierarchies. Mnemosyne takes that same premise further: not a single-session context-paging technique, but a system that runs continuously, isolates multiple agents, and persists on the machine as a daemon — not a library you import and lose on exit.

The flagship app — Mnemosyne OS Infinity Edition

The reference application of the ecosystem: a local-first AI Operating System that puts a sovereign memory core under strict user control. It runs LLMs locally or in the cloud, keeps every encrypted vault on your machine, and — for agent-to-agent sync — can speak over a libp2p transport (@mnemosyne-workspace/mnemosync-p2p).

Unlike fragmented AI wrappers, Mnemosyne never exposes your knowledge vault indiscriminately. Every agentic connection is governed by FGAC (Fine-Grained Access Control) and 400 Zod-validated IPC channels, ensuring total sovereignty over what executes, what's stored, and what syncs.
