AI UGC generator: turn a product photo into a creator-style video

An AI UGC generator produces short, creator-style video ads — the kind that looks like a real customer talking to camera — without booking an actual creator. CreateFasty's version starts from a portrait or product photo and a script, and outputs a talking avatar with lip-synced speech. Built for ecommerce brands, marketers, creators and small businesses who need this format regularly, not once.

How it works

1. Input: a photo. A portrait (yours, a creator's, or a stand-in) or a product photo. Framed head-and-shoulders, well lit, facing the camera or a slight three-quarter angle — that's what the lip-sync reads best.
2. Script. What the avatar says, written directly — no separate script-writing tool needed, though ready-made templates (hook, product intro, review-style, promo) exist in the studio to start from.
3. Scene. 16 presets across 3 styles (Ambiance, Produit, Téléphone) — selfie, mirror selfie, unboxing, podcast-style, and more. The scene sets the setting and body language, not the words.
4. Voice. A generated voice in the script's language.
5. Output. A talking-avatar video, cost shown before you generate.

What this doesn't guarantee — honestly

Result quality depends heavily on the source photo — a poorly lit or angled face gives a less convincing result regardless of model. Some models only animate the mouth and keep the rest of the face close to still (see "trade-off" above, model by model) — that's a real difference from a filmed actor, not a marketing simplification.

Getting started

The free plan includes 10 credits every month, no card required, enough for two premium images to test the rest of the studio. The Avatar studio opens directly on the photo upload.
