How to create an AI influencer: a step-by-step guide
3 chapters · 12 min · Beginner · verified on 9 October 2026
To create an AI influencer, you need a subscription with access to Codex and an active Higgsfield subscription with credits, then connect the plugin in Codex. For your eight-view character sheet, use Codex image generation or GPT Image 2.5 through the plugin. For video, choose Genjutsu in Object Swap mode to replace a character, or Seedance 2.5 to create an original scene. Finish with Codex to check the clip, restore the audio and prepare the final file. ElevenLabs is optional for adding or changing a voice.

This tutorial guides you from an AI influencer idea to a first video. You will learn to prepare character references, replace a person with Genjutsu and finish the edit. You do not need programming experience.
Tools and subscriptions to prepare
Here is what we use in this tutorial. Codex helps with instructions, checks and the final file. The plugin brings the generation tools into the conversation.
| Tool | Access needed | What it does |
|---|---|---|
| Codex | A ChatGPT subscription with Codex access. Creating sheets directly also needs image generation access. | Describe the character, generate a sheet, manage tests and finish the video file. |
| Higgsfield plugin in Codex | An active Higgsfield subscription with credits for the selected generations. Install the plugin in Codex and connect it to this account. | Generate images and use Genjutsu to replace a video character. |
| Optional ElevenLabs | Suitable access if you want to add or change a voice. | Create a spoken line or transform a recorded voice. Keeping the original sound is also fine. |
Install the Higgsfield plugin in Codex and connect your account. Ask Codex to check the available tools and the estimate before generating. Codex usage and the connected service’s credits are separate. Keep your sheet, source clip and accepted results in one folder.

What you will make
Your project is a short clip with a recognisable character. Keep the reference images, your instruction and the accepted video file. Glen provides our examples for sheets and replacement. Naïla and Gérard help explain corrections and voice work.
What you need before starting
- An adult fictional character described in a few lines. The first chapter helps define the face and outfit.
- A reference sheet you will approve before the first video test.
- A short clip with one visible person in your Codex working folder.
The method: approve an output at every stage
Keep your character and identity references throughout the three stages. Change one thing at a time and record why you accept a version. Our examples use several avatars to show different problems, but you can complete the whole process with your own character.
| Stage | What you prepare | When to move on |
|---|---|---|
| Character | A profile and reference images | Every view shows the same person with the chosen traits |
| Video | One short Genjutsu clip | Target, clothes, duration and other people have been checked |
| Editing, optional voice | A final file prepared with Codex and the selected sound | Cuts, sound and export have been checked. Check the line and lips if the character speaks on camera |
What do the tools do?
An avatar is a visual representation. A virtual influencer also has an editorial identity: recurring topics, a tone and recognisable formats. Higgsfield provides character, image and video tools. Its AI Influencer Builder can help make your reference. An existing reference sheet is another option.
Genjutsu can replace a character in an existing video. Object Swap targets an element in the shot. Motion Transfer uses movement to rebuild a scene around new references. We focus on character replacement. Creating a completely new scene is a different workflow.
Six steps to your first AI influencer video
- Define the character. Choose a name, topic and manner of speaking. Write three post ideas to check that the concept can last.
- Fix the appearance. Make an eight-view sheet with Codex or the connected plugin. Compare face, build and outfit, then keep one approved version.
- Choose a simple clip. Use a short clip. Begin with one clearly visible person and few cuts.
- Replace the person. In your Codex conversation, request a Genjutsu character replacement using Object Swap. Identify the person by clothes and position, then explain what should remain. Genjutsu.
- Choose the sound. Keep the ambience, add narration or make the character speak. See voice and video editing.
- Review before posting. Watch the beginning, middle, end and fast movements. Check the face, clothes, other people, sound and duration. Make the fictional identity clear and use the platform’s AI disclosure setting when the realistic content requires it.
Real examples from Gekkode
Glen in the tiny car | YouTube
Glen on the aeroplane | YouTube
Gérard’s fictional interview | YouTube
The car and aeroplane examples have English captions. Gérard’s interview and parody contain French dialogue. These embeds are the original videos, without newly produced dubbing.
Glen’s car clip was made with Genjutsu and checked for timing and audio. Gérard’s original interview was generated with Seedance 2.5 from a character reference and an original dialogue. It is not a Genjutsu swap. This distinction tells you which process to reproduce.
Budget and common problems
Our October 2026 submission estimates were 49 credits for Glen’s tiny car, 77 for the aeroplane and 91 for the two-person car scene. Removing text from the last scene was estimated at another 15 credits. These are dated estimates for specific requests, not guaranteed prices or confirmed net charges. Glen’s kitchen clip used a free generation available at the time. Corrections and retries can still cost credits.
Keeping the same face requires an approved reference and visual checks. Some Naïla corrections still failed to establish the intended identity. A reference helps. It does not guarantee a perfect result.
ElevenLabs can read a script or change a recorded voice. Matching the lips is a separate step.
Start with the character sheet and visual reference, then make one short clip before producing a batch.
