Strip away every visual element other character builders rely on. Rebuild the experience around behaviour. The premise: appearance is a five-minute decision. Personality is the actual relationship.
The lab interface is deliberately clean. A personality canvas on the left. A live chat probe on the right. A versioning panel along the bottom that saves every iteration so you can roll back, branch, or compare.
The canvas exposes eight behavioural axes — warmth, directness, playfulness, intensity, vulnerability, dominance, humour register, curiosity — each scored from zero to one hundred. Underneath, sixteen conversational primitives govern micro-behaviours: how often she asks follow-up questions, how she handles disagreement, whether she initiates topics or waits, how she uses pauses, whether she repeats your phrasing back, how she gives compliments.
Four relationship-dynamic blueprints serve as starting templates: Caring Equal, Devoted Romantic, Mischievous Tease, Quietly Dominant. Each is editable down to the primitive.
The live probe is what makes the lab feel like a real instrument. Adjust a slider. Run a probe scene from a library of fifty test prompts — "she catches you in a small lie," "you tell her you're proud of her." Watch her response generate in real time, scored against your build's stated targets.
Publish completed personalities to a private library and import them into Build My AI Girlfriend, or use them inside the lab's own persistent chat mode.
The most cerebral title on the hub. The favorite among players who came from writing, design, or psychology backgrounds.
