How to create an AI influencer

An AI influencer is a fictional creator: a character with a consistent face, a voice, a point of view and a posting habit, whose photos and videos are generated rather than filmed. The hard part is not making one good image. It is making the same person show up in every video, sounding like themselves, week after week.

Here is the whole process, in the order that saves the most redos.

1. Start with who they are, not what they look like

Write one sentence that answers three questions: who is this person, who do they talk to, and what do they help with? Specific beats glamorous.

• Weak: “A beautiful fitness influencer.”
• Strong: “A tired 40-something dad who meal-preps a week of dinners in one hour on Sundays.”

The strong version gives you an age, a voice, a niche, an audience and a repeatable content format. Everything else (the look, the scripts, the catchphrase) falls out of it.

2. Give them a face that stays the same

Consistency is where most do-it-yourself attempts break. Generating one portrait is easy; generating the same face in a kitchen, a car and a close-up is not. The usual approaches are a reference image fed into every generation, a face-swap pass, or a trained model of the character. Each needs checking clip by clip, because faces drift.

Pick a look that fits the sentence from step 1. An 81-year-old nonna from Queens should look like one, not like a stock model with grey hair.

3. Choose a voice that matches

A talking video lives or dies on the voice. Match age, region and energy to the persona, then keep that exact voice for every video. Changing voices between posts is the fastest way to make followers notice something is off.

4. Write scripts in their voice

Short-form talking videos work best at roughly 15 to 30 seconds: a hook in the first line, one idea, and a sign-off the character repeats. Write the way the character talks, not the way a brand writes. A catchphrase helps people remember them.

5. Film talking videos

A talking video needs three things to line up: the consistent face, the voice, and lip sync that matches the audio. Scene-style videos, where the character acts out the idea in a few locations, add a storyboard step. Review every clip before posting; lip sync and hands are the usual tells.

6. Label it as AI, every time

Make it obvious the creator is fictional:

• Put an AI disclosure in the bio.
• Turn on the platform’s AI-generated content label when you post (Instagram, TikTok and YouTube all have one).
• If a post is paid or sponsored, disclose that separately. An AI label does not replace an advertising disclosure. See the FTC’s guidance for influencers.
• Never invent reviews, testimonials or claims that a real person used a product.
• Never use a real person’s face or voice without their permission.

7. Post on a rhythm and keep the character steady

Pick a format you can repeat (a weekly recipe, a daily tip, a rating series) and keep the character’s opinions and tone consistent. The audience follows the person, not the technology.

What it costs

Doing it yourself means stitching together an image model, a video model, a lip-sync model and a voice model, then redoing clips when the face drifts. In AI Cast Studio those decisions are made for you:

Plans start at $29 a month for 400 credits: one influencer and three 20-second videos. See pricing for the rest.

The short version

1. One specific sentence: who they are and who they help.
2. A face and a voice that never change.
3. Scripts in their voice, 15 to 30 seconds each.
4. Talking videos, checked before posting.
5. An AI label on every post, and honest sponsorship disclosure.
