01Four faders · 18+

Design your AI girlfriend by moving four faders

Warmth, nerve, tenderness, initiative. Those four decide how nearly every message feels, and each one moves on a sentence rather than on a rebuild.

Fictional AI characters only. Nobody here is a real person.

02The detail

Four traits do more work than twenty adjectives

Almost every complaint about a companion app comes down to one of four settings being wrong, not to a missing biography.

When people design your AI girlfriend style character sheets, they write ten adjectives and get a character who feels like none of them. The reason is that adjectives describe a person at rest, and a conversation is a person in motion. What you actually notice is how warm the greeting is, how much she pushes back, how gentle she gets when you are flat, and whether she ever starts anything herself.

So the desk exposes exactly those four. Warmth sets the temperature of the greeting. Nerve decides whether she argues or agrees. Tenderness is the register she drops into when something is wrong. Initiative is who moves the conversation. Every other trait people ask for — playful, clingy, cold, dominant — is a combination of those four sitting at particular heights.

You do not have to get it right in advance, which is the point. Set nothing, read two replies, then move the one that irritated you. Two or three corrections is normally the whole design process, and it stays put afterwards.

What works well

  • Four settings instead of a blank character sheet
  • Every correction takes one sentence, mid-conversation
  • Combinations cover the traits people usually ask for by name
  • The mix is stored with the character, not with the browser
  • Costs nothing to experiment with before any upgrade decision

Worth knowing first

  • Fine-grained backstory is not what this tool is for
  • Two mixes close together can feel similar in short exchanges
  • Characters are fictional adults and are never presented otherwise
  • 18+ only, with the age notice before the roster loads

03On this page

The same four faders, three very different results

Identical controls, different heights — which is easier to feel than to describe.

Nerve high, tenderness low: she argues before she agrees.

Warmth high, initiative low: she waits for you, then meets you fully.

Everything mid, initiative pinned: the mix that keeps a slow week moving.

04In practice

How the first ten minutes usually go

Most people move nerve first. The default politeness of a chat model reads as flat, so they ask for more push, and the tone changes immediately. Warmth is the second correction, usually downward — a character who is too pleased to see you is harder to believe than one who is mildly unimpressed.

Tenderness and initiative tend to get set later, once something real comes up in the conversation. That is the right order: those two matter most when you are not in the mood to steer, and it is hard to know how much of that you want until it happens.

05Quick answers

Designing her — quick answers

01

Do I have to design her before the first message?

No. Every character arrives with a starting mix, so you can talk immediately and adjust afterwards. Designing before you have read a reply is guesswork; two messages tell you more than any form would.
02

What exactly do the four traits control?

Warmth is the temperature of how she greets and reacts. Nerve is how much she pushes back. Tenderness is the register she uses when something is wrong. Initiative decides whether she starts things or waits for you to.
03

Can I give her a name, a job and a backstory too?

You can tell her those details in conversation and she will keep them, but this is a temperament tool first. If a precise, fixed biography is the main thing you want, a full character-sheet builder will serve you better.
04

Will the design reset if I stop talking for a few weeks?

No. The mix is stored with the character, so a gap does not undo it. When you come back she is still the version you tuned, and the context you built up is still there to reference.
