/ about

What it does

Card flipping on eBay is brutal: every card needs a title, a description, a price, and you have to research scarcity to know if you're underselling. Most flippers spend more time listing than finding deals. CardFlow fixes that — bulk-publishes your inventory to eBay with AI-written titles and descriptions tuned to actually sell, pulls live market data so you know when you're the only seller (price up) versus one of many (price competitively), and smart-prices your whole batch automatically. Built for the people who treat card flipping like a real business, side hustle or full-time.
