Designing Your Companion

She's not picked from a catalog — she's built. Every choice you make in the designer travels with every message to the AI, which means the design screen is really a personality dial. Here's what each setting does.

The six personas

The six traits (pick up to six)

Design tip: three or four traits produce a sharper character than all six — Humor + Adventurous + Intelligence is a bantering co-conspirator; Kindness + Supportiveness + Positivity is a soft place to land. All six averages toward pleasant-but-generic.

The look

Six eye colors, six hair colors, plus the persona's art direction — and the look isn't cosmetic: it feeds the image model, so her selfies match the character you designed. Change her from a redhead to silver-haired and the next photo follows suit.

Redesign freely

Settings → Modify Preferences reopens the designer anytime. Chat history persists through redesigns (she just… evolves), while Reset Chat is the clean-slate option — new character, new story. A fun pattern: keep the name, rotate the persona seasonally, and see how the same conversations land differently.

The math checks out: 6 personas × 6 eye colors × 6 hair colors is 216 base combinations before trait selection multiplies it further — “100+ ways to customize” is, if anything, an undercount.

FAQ

Can I change my AI girlfriend after creating her?

Anytime, via Settings → Modify Preferences. History stays unless you Reset Chat.

Which persona should I pick first?

Human for naturalism, Anime for expressiveness — switching later is one tap, so start anywhere.

Do the traits actually change how she talks?

Yes — they ride with every message. Three or four focused traits beat all six.
