Consistent AI avatars your brand can reuse everywhere
Describe a presenter once, keep that description, and render the same look across ads, landing pages and social. One recognisable face without a single scheduling email.
Create your avatar
Step one renders the avatar still from your casting sentence, and step two plays a motion preview of that still.
Describe your product in the prompt — colour, packaging, label — and your AI actor will hold it.
Recognition is built from repetition
People remember faces long before they remember taglines. A brand that puts the same presenter in front of every message accumulates recognition; a brand that uses a different stock model each month accumulates nothing. The obstacle has always been logistics — the same human, available on the same day, in the same wardrobe, every time you need an asset. Working with ai avatars removes that constraint. The description is the asset. As long as you keep the casting sentence stable, you can render that presenter again next quarter without anyone checking a calendar.
Treat the avatar description like a brand guideline. Store the exact wording that produced the look you approved, note the ratio and the lighting, and reuse it verbatim. What varies between assets should be the product, the setting and the framing — never the casting sentence itself.
What a persistent avatar buys you
One face, every placement
The same presenter can appear in a 9:16 story, a 1:1 feed unit and a 16:9 site header. Because each is rendered natively at that ratio, you get consistency of person without the cropping compromises that come from stretching one photo across every surface.
The look is documented, not booked
Your presenter lives in a text file rather than in someone’s calendar. New team member, new agency, new market — hand over the casting sentence and they can produce on-brand assets immediately, with no onboarding and no rights conversation.
Evolve deliberately
When the brand shifts, you change the description on purpose: softer wardrobe, different age band, warmer light. Version the sentence and you have an auditable history of how your on-camera identity changed, which is more than most brands can say about their stock photo choices.
Establishing your avatar
Spend the effort once on the casting sentence, then reuse it.
Draft the casting sentence
Write the presenter in detail — age band, hair, wardrobe, posture, expression, backdrop. This paragraph becomes a reusable brand asset, so it is worth more care than a throwaway prompt gets.
Lock it by rendering
Generate at the ratio you use most, review honestly, and revise the sentence rather than accepting a near miss. Once a render matches the identity you want, freeze the wording exactly as it stands.
Preview, then reuse across assets
Play the motion preview to check the presenter reads well moving, then append different products and settings to the frozen casting sentence for every subsequent asset you need.
Avatar questions
Consistency tracks how stable your description is. Keeping the casting portion word for word — same age band, hair, wardrobe and lighting — keeps the look close across a set. Rewriting even a few descriptive words tends to shift the face, so treat the sentence as fixed text.
Yes, and many should. A B2B explainer and a weekend lifestyle post often want different presenters. Maintain a short roster of casting sentences, each with a documented purpose, rather than trying to make one face carry every context.
The presenter is generated from your description rather than filmed from a performer, so there is no talent booking, no day rate and no usage window to renew. Normal advertising rules about claims and disclosures still apply to whatever the ad says.
A photoreal still in any of six ratios — 9:16, 4:5, 1:1, 16:9, 4:3 and 3:4 — plus an optional motion preview of that still. Render the same casting sentence at each ratio you need instead of cropping one master image down.
