How AI Estate Sale Cataloging Works, Step by Step

AI estate sale cataloging comes down to one line: you photograph the lots, and the software writes the catalog, reading each photo, describing each item in catalog language, and handing back listings ready to publish. An estate is the hardest version of this job, a houseful of unrelated lots all at once, which is exactly where the hours come off.

Step 1 - Photograph the lots. Shoot each lot the way you'd stage it for the block. According to AuctionNinja's photography guidance, every lot should carry at least three photos from varying angles, and the AI reads all of them, front, back, maker's marks, labels, not just the hero shot.

Step 2 - Upload and sort into lots. The photos come in and get grouped into lots. According to Estimint's cataloging analysis, doing this and the describing by hand runs 46-64 hours for a 200-lot estate; the describing is the part the software collapses.

Step 3 - Write the descriptions. One action, and every lot comes back with a title and description in catalog language. Because an estate mixes categories, the routing is the whole game: glassware, tools, and jewelry each pull from their own vocabulary rather than getting flattened into one generic voice.

Step 4 - Values, comps, and photos. In the same pass, the tool can add a value estimate, pull real market comparables, and produce a clean product photo, the parts of cataloging that otherwise mean a second round of research after the writing's done.

Step 5 - Review and export. You read the drafts, fix what only you'd catch, and export to your platform. According to AIM (2025), manual cataloging moves at 15-25 lots an hour; Gavelist writes 1,000+ lots in about 10 minutes, so your time goes to the review, not the typing.

Volume is the reason any of this matters. According to EstateSales.net (2024), hybrid sales, online and in-person together, saw a 50% jump in volume, and descriptions are the bottleneck all that new volume runs straight into.
