Most AI tools would rewrite your listings and hand you the same template every seller is using, when knowing which lever lifts your specific sell-through is the whole game. Compass works the other way. It pairs the speed of AI with coaching and taste, so the plan fits your shop and your stock and you learn to read what works rather than renting a black box.
Compass starts with where your effort pays back, because for a one-person shop the scarce resource is your time, never a shortage of things to try. It surfaces the listing-title, photo, and pricing actions that lift your search ranking and sell-through against what your category typically does, and it names the reason behind each one so the judgement stays with you for the next listing. It sets your channel mix to fit a seller who lives on the marketplace, calibrated to eBay's search and promoted-listings mechanics rather than a generic ecommerce model. It teaches you to bring buyers back through the off-platform follow-up and the repeat-buyer habit that earns a sale without paying the finding cost twice.
You stay the seller deciding what to stock and list, you learn why each one pays back, and you have a senior marketing executive's judgement beside you, working out what wins the sale so you can do it again.
