Bespoke Personalities
Synthetic Personalities for your AI agents and more.

Three gestures
How it works
Synthesize
Lock this core personality along with an agent identity to form a permanent Persona. Once locked a full personality profile is synthesized including a Character Study and character portrait (for easy reference).
Deploy
Generate an NT Persona Kit — the files you will need to configure your agent's personality wherever it lives.
The category
Synthetic Personalities
An agent's personality shouldn't be a word salad of adjectives pasted into a prompt. NeoThymos treats personality as engineered structure — grounded in a real psychological model, and portable across every framework & platform your agents run on. Build it once; it holds together, it has a home and it comes with you.

Built for agent builders
Today, NeoThymos is for the people giving AI agents a character that holds up in conversation — a grounded personality instead of a hand-typed paragraph.
The same craft reaches further. Character Bibles for fiction, NPCs for TTRPGs, and casts for game studios are coming domains of the same grounded model — and the Personalities you build now carry into them.
