AI Pricing Tool for Resellers

Price smarter, flip faster

In plain English

Underpriced AI tells resellers what an item is worth from a photo in seconds. People who flip thrift and garage sale finds use it to price faster and buy smarter. They pay a subscription. The founder built it for his wife, who used to spend hours pricing items by hand.
