Frequently asked questions
How does an AI UGC video generator work?
You upload a product photo or type a short idea, write or paste your script, then pick an AI creator, a voice and a language. The AI UGC video generator produces a vertical clip in minutes. You can generate several variations, review them and download the ones you want to run as ads.
Do I need filming or editing skills?
No. There is nothing to film and nothing to edit. AI creators present your product and speak your script, so you get a ready-to-post UGC ad straight from your browser. Fattly is a web app, so there is no software to install — you just describe what you want and generate.
How much does it cost and are there free credits?
Fattly runs on pay-per-credit pricing, and credits never expire. A subscription is optional, not required. You start with 10 free credits and no card, so you can try the AI UGC video generator, create your first clips and only pay for what you actually use after that.
Which platforms are the videos made for?
Clips come out in a vertical format built for TikTok, Instagram Reels and Facebook ads, where UGC-style content performs best. You can generate several variations to test different hooks, creators or languages, then download the winners and upload them straight to your ad accounts or social profiles.
Can I choose the voice and language?
Yes. For every clip you pick the AI creator, the voice and the spoken language, so you can localize the same script for different markets. That makes it easy to run one product idea as native-sounding UGC ads across several countries without hiring a separate creator for each one.
