Build a character from traits

Describing a face in words is hard. A prompt that tries to pin down a nose, a jawline, and a hairstyle at once often comes out different every time. The Character Builder replaces the prompt with a set of choices: you pick the traits you want from lists, and it generates a full-body standing portrait of a person who has them.

The attribute groups cover appearance from head to toe: gender, ethnicity, hair color, length, and style, skin tone, body type, eye color and shape, face shape, nose shape, facial features, age range, and clothing style. Every group is optional. Set only what matters to you, and the model fills in the rest so the portrait still looks like one believable person.

When you like the result, save it as a character. A saved character has an @handle that you can mention in later prompts and pick in other apps, so the same face shows up in every image and video you make with it. It is the most direct way to start an AI character you plan to reuse.

Start with the traits that define the character, usually the age range, the hair, and the clothing style, then add details. A few deliberate choices give the model a clear direction and leave room for a natural result. Filling every group can make a character that looks assembled rather than real.

Facial features take more than one choice, so you can combine details such as freckles, dimples, or a beard. Clothing style sets the overall look of the portrait, from casual to formal to fantasy. Change one group at a time between runs to see what each choice does.

• Start with three or four groups, then add more.
• Change one group per run to see its effect.
• Generate a few portraits with the same traits and keep the best.

Guava is the default, a model family made for photoreal people. Switch to a Mango model or another Guava model from the Model menu for a different look, or when you want an illustrated or stylized character. The resolution choices depend on the model, and the portrait always comes out in a 4:5 frame, tall enough for the whole figure.

Running the same traits on two models is a quick way to find the style you want before you save the character.

Press Create Character on the portrait you want to keep, and it is saved with an @handle. Write that handle in a prompt to put the character in a new image or video, or pick it in an app that takes a character, and the face, hair, and build come along.

A full-body portrait makes a good reference, because it shows the outfit and the build as well as the face. For an even fuller one, turn it into a character sheet with front, side, and back views, then save the sheet as the character.

Stories usually need more than one character, and a cast reads best when its members look clearly different. Vary the traits that are easiest to tell apart at a glance: the age range, the hair color and length, the body type, and the clothing style. Two characters with the same hair and build can blur together in a busy scene, even when their faces differ.

Give each character a place in the look of the cast. A hero in bright, simple clothes, a mentor in muted, formal ones, and a rival with a sharper face and darker colors are easy to follow from scene to scene.

When the cast is ready, put two of them in one clip with Scene Builder to check that they read as different people side by side.

Put two characters in one short video with Scene Builder, make them perform a song with Music Video, or recast a clip with Video Character Swap. Dress them in new looks with Outfit Swap.

To start from a picture instead of a list, Character Builder: Muse begins with a starter image and refines the face step by step. For a creator persona with the same look across posts, see the AI influencer generator.
