why we built these
the lookups a jeweler does every week.
bling ai makes jewelry photography, but the day-to-day of running a jewelry business is full of small, recurring lookups: what a stamp means, what a piece is worth by weight, what a customer's ring size is in another country's system.
so we built the ones we kept reaching for, and made them clean and free. no account, no email wall. if they save you a minute, that's the point.
when you're ready to photograph the pieces themselves, the guides and the app are here for that.
ready when you are
stop shooting. start posting.
free to start. one tap to install. no account needed to try.
