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