01 THE IDEA

A Shopify app that uses AI voice cloning (ElevenLabs) and video generation to send hyper-personalized 30-second recovery videos to abandoned cart customers. When a cart over $100 is abandoned, the app grabs the shopper's first name, product image, and founder's cloned voice to generate 'Hey Jane, I noticed you loved these sneakers — here's 10% off' as a short personal video emailed via Shopify's marketing API.

The novelty factor alone drives opens and conversions far above generic email sequences. Pricing at 1% of recovered revenue aligns incentives perfectly — the tool only makes money when the merchant makes money. The growth channel is an X/Twitter account documenting AB test results and conversion lifts, targeting the massive community of Shopify store owners obsessed with CRO metrics.

03 THE VERDICT

Genuinely novel approach in a proven high-value market. Revenue-share pricing eliminates merchant objection ('it only costs me money when it makes me money'). The novelty of AI voice-personalized video creates strong word-of-mouth and demo virality. Technical complexity is moderate and well within reach of a developer founder. First-mover advantage in Shopify app store is real and valuable.
