Promo Studio
Promo Studio
A whole video ad campaign from one conversation. Tell your agent what you sell, or paste your website. Promo Studio writes the script, shows it to you, and once you approve it, renders finished MP4s with a natural voiceover and word-by-word captions.
Everything runs on your own computer. 1 video or 500 costs the same: nothing. No video API, no credits, no length limit.
Your app, inside a phone
Give it your website link. It takes phone screenshots by itself, picks up your logo and brand colours, then animates a pointer tapping and scrolling through your app.
One script, every format
Vertical for TikTok, Reels and Shorts. Landscape for YouTube. Square for feeds. All rendered together from the same script, with layouts that adapt to each shape.
Test your opening line
The first second decides whether people keep watching. Ask for several hooks and you get the same ad with different openings, ready to A/B test.
Hand-drawn, editorial, or bold
Line art that draws itself, numbers that count up, before and after, checklists, charts, a countdown for real offers, and your own photos. Four looks to start from, and any colours you like.
Long-form explainers too
A 15-second ad or a 10-minute YouTube explainer. It works the same way.
Thumbnails, covers and subtitles included
A YouTube thumbnail, a vertical cover, and a subtitle file (.srt) for every video.
How it works
Install it, then say "Set up Promo Studio." It's a one-time setup of a few minutes.
Ask for what you want:
Make a 30-second TikTok ad for my app. Here's the website: myapp.com
Make the full campaign for my candle shop. Warm, hand-drawn, a British woman's voice.
It asks a few questions and shows you the script first. Nothing renders until you approve the words.
You get finished MP4s. Ask for changes in plain words: "make the first line punchier", "use a man's voice", "make a YouTube version".
