Founder on-screen talks from the bottom third while the app demo fills the screen above video, made for SaaS, optimized for TikTok in 9:16 路 Voiced in English
An AI video ad tool for small and mid-sized businesses. The owner pastes their website and gets back a finished ad: the tool reads the site, works out the offer and the audience, picks an actor, writes the script and renders the video. Hooks are drafted in bulk, ranked against each other and tested on simulated customers before anything is written. Founders can also clone themselves from one photo and speak more than 70 languages.
The buyer scrolls TikTok like everyone else and runs a business that has no video ads yet. Hiring creators and editing feels like a project they will never get to. They trust people over polished brand spots, and they decide in the first second whether something is an ad to skip or a person worth hearing out.
A founder clone in a native split screen layout fits because it looks like a creator explaining a tool, not a commercial. The face anchors trust, the demo above it carries the proof, and the founder can record new versions without filming again.
The prompt
Vertical 9:16 founder talking head, about 58 seconds, one continuous take, generated from a custom actor made from one photo of the founder with the founder's cloned voice. Setting: a small home studio, teal blue painted walls meeting in a corner behind the founder, a strip of warm wooden floor at the bottom of frame, soft cool key light from camera right and a blue rim light on the hair. The founder, early thirties, short beard, dark hair tied back, black hoodie, sits behind a black podcast microphone on a boom arm that enters from the left foreground. Eye level, locked off camera, looking straight into the lens, relaxed and conversational, small hand gestures on the key words. Wide enough framing that the head and shoulders sit in the lower 40 percent of the frame, with clear wall above for on-screen content, founder centred. Dialogue: "You know you can paste your website and get a video ad back? Most businesses still don't have a single video ad, because it feels like a whole project. Find a creator, film, edit, so they just never start. So let me show you how it works now. You paste your website into the app. It reads it, figures out what you sell and who it's for, picks an actor, writes the script, and makes the video. And your first one is free. You don't even need an account. But that's not the craziest part. Before it writes anything, it comes up with up to 64 hooks and makes them fight each other like a tournament, and then 20 virtual customers built from your audience say if they'd actually stop scrolling. So the hook in your video is the one that won. And funnily enough, that's not even where it ends. You can make your own actor from one photo, have them speak more than 70 languages, and post the video to TikTok, Instagram and YouTube without leaving the app. If you want to try it with your own website, comment video and I'll send you the link." Burned in captions, bold white sans serif, one short line at a time, placed just above the founder's head, keywords highlighted in deep blue.Why this works
This is the same founder script recut for TikTok, and the layout is the point. The founder sits in the bottom third from the very first frame, the way native split screen creators film, so the feed reads it as a person talking rather than an ad. Everything the script describes plays in the top two thirds: the pasted address and the loader in the opening seconds, three empty dashed slots and a glowing zero on "most businesses still don't have a single video ad", then the app itself, framed scene by scene for a tall screen.
Captions sit on the seam between the two halves, exactly where the eye travels between face and demo, so nothing has to be read twice. White title cards, FREE, CRAZIEST, 70+ LANGUAGES, punch in above the face without ever covering it, which keeps the human anchor on screen through every cut. The face grows for two beats only, "let me show you" and the closing call to action, so the size change itself signals that something matters. The demo layer and the captions were built in the edit on top of the generated talking head.
Fifty eight seconds is long for TikTok, and the script earns it with two open loops spaced about fifteen seconds apart and a tournament of hooks that is unusual enough to keep watching. The comment to get the link close is native to the platform, costs the viewer one word, and every comment pushes the post to more feeds.
