Fattly vs Runway at a glance
Runway is one of the best-known AI video tools, popular with creators and filmmakers for high-quality generative video. Fattly is an all-in-one AI content platform where video sits next to image, voice and UGC. They overlap on AI video but solve slightly different problems — so the right pick depends on what you actually need to ship.
Where Runway is strong
Runway built its name on creative, cinematic video generation and a set of pro editing tools. If your work is pure high-end video — film-style shots, VFX-leaning experiments, motion work — it is a tool that many creators reach for first. It is a genuinely capable tool at what it focuses on.
Where Fattly is different
Fattly is built around ready-made workflows for ads and content: UGC-style ads with an AI actor, voiceovers and dubbing in Polish, German, Spanish and French, virtual try-on and avatars. Video with sound comes from models that generate the audio together with the picture, such as Gemini Omni Flash 1.1 and Seedance 2.5: dialogue, ambience and effects in one pass. The interface works in English, Polish, German, Spanish and French, and 40+ AI models sit under one login, so a whole campaign lives in one place.

Which should you pick?
If your work is mostly creative, cinematic video and you want professional video editing tools, Runway is a strong choice. If you want ready-made workflows for ads and content — UGC with an AI actor, voiceovers and dubbing in your language, try-on and avatars — next to your images and video, Fattly is built for that. Plenty of people use one tool for one job and another for the rest — the honest question is which describes your workflow.

The fastest way to compare is to run one scene through Fattly yourself. You start with 10 free credits and no card. They cover a few images, not video: the cheapest clip costs 30 credits and a clip with sound costs from 80, so a real video test needs the smallest pack of 150 credits.
