How the parts that matter work.
Four decisions carry the draft: the price, what's read from the piece, the cutout, and the placement.
The price
The extreme tenth on each side is trimmed, then the median taken. Absent sold data it draws on active asks, discounted, always a range, never false precision.
Attribution
Material, colour, closure, condition, and an estimated size are read from the photographs. The house is read from a visible label when there is one, and inferred from its design signatures when there isn't, hardware, silhouette, stitching, offered as a lead to verify. Sizing that needs a label stays with you.
The cutout
The background is lifted and the piece squared and centred, a cleaner reading, and an image ready to list on a white ground.
Placement
Category and item specifics are resolved for you; the listing is composed and, only on your word, published. Poshmark is written but placed by hand.
The machine learning
Three models do the reading, one cloud and two on your own machine. The price, deliberately, is not one of them.
Vision-language model
Reads the piece from its photographs: the house, condition, flaws, an estimated size, and the finished listing copy. It also locates each sellable piece in a full-outfit photo, so a whole look is drafted piece by piece. Runs in the cloud.
Segmentation, U²-Net
A convolutional network that lifts the piece from its background for the cutout. Runs locally.
CLIP and nearest neighbour
Encodes the photo into a vector and matches it against your own reference library to suggest a house. Runs locally, no keys.
Pricing is statistics
The price is a trimmed median of real comparables, not a model. Honest and debuggable where a predictor on thin resale data would not be.
What it won't do
It won't authenticate
It can name the house from a mark or its design, but that is identification, not authentication. For high-value pieces, verify with the house or a service before you list.
Dimensions are estimates
It estimates a size from the piece and its type, useful, but a photograph has no true scale. For an exact fit, measure with a tape before listing.
It won't host images
The cutout is produced; eBay needs a public URL, so you host it.
It won't post to Poshmark
The copy is written; placing it there is yours.
