Product URL to a vertical ad, approved in Slack

A form or a webhook receives a product page URL. The page is fetched and cleaned. OpenAI writes a hook, a script, a caption, and three visual prompts. Sisif renders each prompt as a silent clip. Slack asks the team to pick one or reject them. The approved file is published as an Instagram Reel.

Marketers who want a product-page URL to become an ad, with a person approving it before it posts.

Each clip is $1 for 5 seconds at 720x1280. The workflow file is free.
