Lowball Lab helps secondhand buyers decide what to offer before messaging a seller.

Use it when a deal looks interesting but you need fast math: paste a listing link, screenshot, or text, or enter seller ask, resale value, resale fees, pickup cost, risk flags, profit goal, and leverage.

Link import reads one user-pasted public listing link from your device when possible. If a site blocks it, paste listing text instead. No background crawling, marketplace account connection, paid pricing API, or AI pricing API is used.

Screenshot import reads one user-picked screenshot locally to help fill listing text. Screenshots are not uploaded to a developer server.
