What heyfish.ai is
heyfish.ai is an AI video advertising platform built for UGC style ads using digital humans. You write a script, choose from a large library of realistic AI actors, pick a voice and language, and the platform renders a finished ad in minutes. It supports precise lip sync and natural expression across many languages, and exports at 4K with commercial licensing and no watermark on paid plans. Two features stand out: two-person dialogue digital humans, and AI actors that hold and showcase a real product you upload. Voice cloning is available from a short audio sample, and AI image generation is included. The site advertises enterprise-level security and API access, and a three-day trial for one dollar.

What to watch out for
Voice cloning is the sharpest risk here. Cloning a voice you do not own, or using a cloned voice to imply an endorsement, can breach platform rules and local law, and the consequences are yours to carry, so get clear permission and label synthetic media where required. Digital humans can still look synthetic on close inspection, which may hurt trust in some categories, and ad platforms increasingly scrutinise synthetic content. The trial is cheap but short, and the useful features such as 4K, longer clips, and commercial rights sit behind paid plans. Numbers quoted on the page, such as actor and language counts, differ between sections, so confirm current limits before you plan a campaign.
