Founder on-screen demos an AI ad app as glass UI cards morph around a corner webcam video, made for SaaS, optimized for YouTube in 16:9 路 Voiced in English
An AI video ad tool for small and mid-sized businesses. The owner pastes their website, the tool reads it, works out what the business sells and who buys it, picks an actor, writes the script and renders a finished ad. Before writing, it drafts dozens of hooks, ranks them and tests the best on simulated customers. Custom actors from one photo, more than 70 languages and direct posting to social platforms round it out.
The buyer is an owner or a one person marketing team that knows it should be running video ads and has none. Video feels like a project: find a creator, brief them, film, edit, revise. So it never starts. They have seen AI tools overpromise and want to see the steps first.
A founder demo fits because it answers the two questions this buyer has, does it really work and who is behind it, in one take. The problem is stated in the buyer's own words, then each step plays on screen while the face stays in view, so claim and proof arrive together. A free first video with no account and a comment to get the link close keep the ask small.
The prompt
Horizontal 16:9 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. Medium close-up, founder centred slightly right of frame. 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 line at a time in the lower third, keywords highlighted in deep blue.Why this works
The opening line is a question, not a pitch: "You know you can paste your website and get a video ad back?" It describes the whole product in one sentence a business owner can picture, and the first four seconds show it literally with no face yet: a button, a pasted address, a loader and a finished vertical ad, all one shape morphing under a cursor. The second line names the pain, most businesses still don't have a single video ad, and a glowing zero lands on screen before the founder explains why.
From there the face is never gone for long. It moves between full screen, a card beside a project board and a tilted corner webcam while the app works next to it, so every claim has its proof in the same frame: the site being read, the actor grid locking on a match, the script typing itself, the render resolving out of a pixel mosaic. Two open loops, "that's not the craziest part" and "that's not even where it ends", each cut to a fast white title card, which resets attention right where a one minute video usually starts losing it. This motion layer, the glass interface and the captions were built in the edit on top of the generated talking head.
Horizontal 16:9 at just under a minute suits YouTube and a website hero, where a curious buyer wants the full flow before committing. The close asks for the smallest possible action, one word in the comments, after the script has said twice that the first video is free and needs no account.
