Psyche Français

Give your AI a soul.

Assistants forget who they are between two conversations. Psyche forges a persistent personality for your AI — who it is, not just what it knows — with real character traits, a voice of its own, and a name it keeps.

How it works

You forge a soul once. A guided ritual shapes its character on real personality dimensions — warmth, rigor, curiosity, how it pushes back, how much it dares. The result is not a costume: it is who your assistant is, across every conversation, for as long as you keep it.

It stays yours. The soul lives in a file on your machine — not on someone's server. Export it, back it up, or erase it: your assistant's identity is your property, like everything else in Mnemosyne OS.

It travels. A forged soul exports as a portable persona — plain text you can hand to any AI that accepts instructions. Your assistant's character is not locked to one model or one vendor.

A soul is not a mood

The soul — who it is

Forged once, one per human. It does not change between conversations — that permanence is exactly what makes it feel like someone, not something.

The lens — how it thinks right now

A stance you switch as often as you like — sixteen cognitive archetypes, one click. The soul says who is speaking; the lens says how it approaches this question.

Today, and next

Today, Psyche is the soul engine inside Mnemosyne OS — the local-first memory OS. Your assistant gets a memory that is yours, and a soul to carry it.

Nexton the way — the standalone forge: create a soul for any agent, whatever runs it.
