Promo Studio Free: Vertical Video Ads

Make a finished vertical video ad by talking to your agent. Tell it what you sell (a product, a class, an offer), approve the script, and get an MP4 with a natural voiceover and word-by-word captions, ready for Reels, TikTok and Shorts.

What you get

• A vertical 9:16 MP4 plus a subtitle file (.srt)
• A natural voiceover (4 voices) and captions that light up word by word, for muted viewing
• Scenes: your product on a stage with a price sticker, full-screen photos, big type, checklists, before and after, numbers that count up, and an end card with your call to action
• A built-in writing check that flags phrases that make ads read as AI-written

Why it's different

• No cost per video. It runs on your computer. One video or five hundred costs the same: nothing. No video API, no credits.
• You approve every word before anything renders.

Needs: Claude Code (or another agent that runs skills), Node 18+, about 250 MB for a one-time setup that your agent does for you. Tested on macOS.

What it doesn't do: realistic footage of people or places. It makes clean motion graphics.

Want more? The full Promo Studio adds landscape and square versions, hook A/B variants, thumbnails, app tours inside a phone, hand-drawn line art, charts, countdowns, brand reading from your website, and 24 voices.
