How to make an AI influencer

An AI influencer is a fictional person you design once and then publish as a creator: photos, short videos, product posts and trends, all with the same face. The hard part is not generating one good image. It is generating the hundredth one and having it still look like the same person.

This guide walks through the process we built Supermodel around: write a casting brief, pick a face, lock it in a character sheet, then produce content from that sheet.

1. Pick the niche before the face

Start with what the account posts, not with what the person looks like. A finance explainer, a get-ready-with-me beauty account and a comedy skit account need different people: different age, wardrobe, energy and voice. Write one sentence for the account (“90-second money tips for people in their first job”) and let it drive every choice that follows.

• Who watches it, and where (TikTok, Reels, Shorts)?
• What does a typical post look like: talking head, outfit check, skit, product demo?
• What would make this person believable in that niche?

2. Write a casting brief

A casting brief is a short list of traits: gender, age range, ethnicity, skin tone, face shape, eyes, hair colour, length and style, body type, style and vibe. Be specific where it matters to the niche and leave the rest open. “Late twenties, warm, slightly sarcastic, vintage streetwear” gives a model more to work with than a list of adjectives.

You can also write the brief as a paragraph, or start from a reference photo of yourself if you want an influencer based on your own look. Only use photos of yourself or of someone who has given you explicit permission.

3. Generate candidates, then choose

Generate several candidates from the same brief and compare them side by side. Look for a face that reads clearly at phone size, has one or two memorable details, and fits the niche at a glance. If none of them work, change the brief rather than regenerating endlessly: the brief is the lever.

4. Lock the face in a character sheet

This is the step most people skip, and the reason their influencer drifts after three posts. A character sheet is a set of reference images of the same person: front, three-quarter and profile views, full body, and a few expressions. Every later image and video is generated from those references, so the model always has the same face to match.

In Supermodel the character sheet is generated automatically when you keep a candidate, and it is passed to every photo, video and copy-paste reshoot.

5. Give them a voice and a wardrobe

Consistency is more than a face. Write down how they sound (pace, accent, tone) and three or four outfits they wear on rotation. Reusing the same voice description and wardrobe in your prompts makes the account feel like one person rather than a series of lookalikes.

6. Produce content from proven formats

Short-form platforms reward formats, not just faces. Instead of inventing every video from scratch, take a format that already performs in your niche and reshoot it with your influencer: the same hook, pacing, cuts and captions, with your cast in the shots.

1. 01Find a video in your niche that clearly overperformed.
2. 02Break it into shots: timing, framing, action, on-screen text, sound.
3. 03Regenerate each shot with your influencer and reassemble it on the same beats.
4. 04Post, label it as AI content, and watch what the audience responds to.

7. Label it as AI

TikTok, Instagram and YouTube all ask creators to label realistic AI-generated content, and sponsored posts need an ad disclosure on top of that. We cover the details in our guide to AI influencer disclosure rules.
