Consistent character AI works in two steps. First you define the character once, in a character sheet with fixed features and a handful of reference images. Then you create every new scene with those reference images instead of text alone. Tools with a dedicated feature for this include Midjourney (up to four reference images), Google's Nano Banana (up to five character images), Ideogram (up to five reference images; a character from a single image can also be saved) and FLUX.2. None guarantees it: OpenAI itself writes that its model may occasionally struggle to keep recurring characters consistent across generations. Everything in this article: as of November 2026.
This article covers the recurring character: mascot, brand character, drawn avatar. Free tiers and what you may do with a single image are covered in Creating AI Images: Free and Free to Use. Text in images, style and resolution are compared in AI Image Generation Compared.
Character, avatar, persona: one word, four meanings
"AI avatar" can mean four different things:
What goes on a character sheet
An example: an accounting firm wants an owl as a mascot for Instagram and its website.
Black Forest Labs recommends hex codes in FLUX.2 prompts for brand consistency. The "Not allowed" row keeps out what models like to add on their own.
Tools with character features at a glance
As of November 2026, from the providers' documentation and pricing pages, without a comparison test of my own. The general comparison of image tools is in AI Image Generation Compared; here, only what matters for characters.
With Gemini, FLUX.2 and Midjourney, keep the reference images in a fixed folder next to the sheet. Ideogram saves a character from a single image for the Ideogram 3.0 Character app. Prices change often; check them before a series.
Public or private: who else can use your character
Ideogram's terms let other users remix public outputs, everything on Free is public, and your output "may not be unique". At Midjourney, only Stealth Mode (from Pro) keeps images private.
Under contract, the images are yours at Midjourney and Ideogram. Copyright is a separate question. Germany's Federal Ministry of Justice wrote in March 2024 that purely AI-based content enjoys no copyright protection; copyright only applies if the basis was originally created by a human, decided case by case. So you can hardly stop others from using a purely generated character. If you draw the base character yourself, you may be in a different position. The line is open, and this is not legal advice.

Real people as avatars: consent and disclosure
This is not legal advice, just the operator's perspective under EU and German law. If the character carries a real face, yours or an employee's, German law starts with Section 22 of the Art Copyright Act (KunstUrhG): images of a person may only be distributed or publicly displayed with that person's consent. Manipulated images that look authentic can also violate personality rights, according to the Federal Ministry of Justice. For a photo avatar of someone else, get consent first.
Google's personal avatar in the Gemini app (18+, account holder only) is currently not available in the EEA, Switzerland or the UK, according to its help page. In the EU, use your photo as a reference image instead.
On top of that comes Article 50 of the EU AI Act, which has applied since 2 August 2026. Paragraph 4 requires deployers, anyone using AI professionally, to disclose deepfakes. Article 3(60) defines a deepfake as AI content that "resembles existing persons, objects, places, entities or events and would falsely appear to a person to be authentic or truthful". The Commission names three cumulative criteria: resemblance, an existing subject, a false appearance of authenticity. A drawn owl with glasses hardly qualifies. A photorealistic avatar of your employee in a scene that never happened can. Then you need a visible label; per the Commission, the provider's invisible watermark isn't enough. The wording and all deadlines are in AI Disclosure Rules Under the EU AI Act.
Talking video avatars, briefly
"AI avatar" often means a face that speaks your script. As of November 2026: HeyGen has a Free plan with three watermarked videos a month and one custom video avatar; the Creator plan costs $29 a month, or $24 a month billed annually. Synthesia has a free Basic plan with a watermark, Starter costs $19 a month and includes three personal avatars per the pricing page, Pro at $89 a month includes five. Consent with these services is covered in AI Video Generator vs. AI Video Editing. If the character should get its own voice too, continue with AI Voice for Videos: Narrator Without a Mic.
Where Conny comes in
In my business, Conny, my AI employee for content, handles the content. I give her a topic, a link or a recording, and she turns it into hooks, scripts, captions and editing briefs for Eddi. She invents no personal facts about me, and posting stays my gate. Why a character sheet fits the way she works is on her page: she runs on Claude, steered by fixed rulebooks, and without that rulebook the same AI delivers generic instead of fitting suggestions.
A character sheet is that kind of rulebook, just for images. And AI image generations cost money; larger batches only run with my approval. A defined character means fewer series generated twice. How a fixed character fits into a posting workflow is shown in AI for LinkedIn Posts: A Step-by-Step Guide. For carousels where the character guides readers across several slides, see Instagram Carousel: Size, Slides, Structure.
Frequently asked questions
Can I create an AI character for free?
Yes, with limits. Ideogram's Free plan gives 30 credits a week with a Google, Apple or Microsoft sign-in, but everything on it is public. The Gemini app works without a subscription in 1K. More on free tiers in Creating AI Images: Free and Free to Use.
Which AI keeps a character most consistent?
There's no general answer, and this article includes no independent test. Use your own character: three reference images, ten scenes, then compare image one with image ten.
Do I have to label an AI mascot?
Under Article 50 of the EU AI Act, mainly if it's a deepfake that resembles a real person and would falsely appear authentic. A clearly drawn fictional character usually doesn't meet the Commission's criteria. Platform rules may apply on top.
Do I own the character the AI generated?
Under contract, usually yes, at Midjourney and Ideogram. But according to Germany's Federal Ministry of Justice, purely AI-generated content gets no copyright, so others can generate a very similar character.
What to do next
Write the character sheet before you generate the first image: name, role, build, three colors as hex codes, one fixed feature, one "not allowed" row. Then create the base image, two views and three expressions, keep them in one folder and run the ten-scene test. The character goes live only when image ten still matches image one.
Conny's template is in my AI Employee Framework community, as a ready-made template in Premium, with the production workflow for hooks, scripts, briefs, approval and review. Everything about it is under Community.
