01

Four photos are all you need to grade clothing

Shoot the front, the back, the label and a close-up of anything worth a look. A phone and a window are enough.

Use the iPhone app, or upload the photos in a web browser.

AI checks the fabric, seams, buttons and labels

GradeThread looks at every part the way a careful buyer would, against one published standard.

On this shirt it found light pilling on the right cuff and some fuzz on the flannel. No stains, holes or loose seams.

Five grading factors, each with a fixed weight

The grade weighs five factors: Fabric Condition 30%, Structural Integrity 25%, Cosmetic Appearance 20%, Functional Elements 15% and Cleanliness 10%. Each one gets its own score and a written reason.

  • Fabric Condition: 7.0 out of 10. Some fuzz on the flannel and light pilling at the right cuff.
  • Structural Integrity: 8.5 out of 10. Seams, collar, cuffs and hem are all intact.
  • Cosmetic Appearance: 7.5 out of 10. Mild creases and a little color softening at one cuff. No stains.
  • Functional Elements: 8.5 out of 10. Every button is there, plus a spare on the label.
  • Cleanliness: 7.5 out of 10. Looks clean in every photo. Smell can't be judged from a photo.

04

A condition grade from 1.0 to 10.0. This shirt is a 7.8.

The five scores combine into one grade. A 7.8 is Very Good: light, even wear that doesn't change how the shirt looks or works.

Free grades are Standard grades, back within 48 hours at most. Need to list today? An Express grade is back within 1 hour for $12.99.

05

A public certificate any buyer can check

Every grade gets a public certificate with its own number. A buyer opens the link and sees the same photos and scores you did.

Your grading photos are kept in private storage. Buyers see them on the certificate.

Then AI writes the eBay listing for you

FlipDesk's AI listing generator writes the title, item details and a description that names the grade, and puts them in an eBay draft. You check it and publish.

Paid plans also cross-list the same item to Poshmark, Mercari and Grailed through the GradeThread Lister browser extension.

How to grade clothing condition with GradeThread

A GradeThread condition grade is a number from 1.0 to 10.0 for a pre-owned garment, scored from photos. It weighs five factors: Fabric Condition (30%), Structural Integrity (25%), Cosmetic Appearance (20%), Functional Elements (15%) and Cleanliness (10%). Each grade falls in one of seven named tiers: New with Tags (NWT), New without Tags (NWOT), Excellent, Very Good, Good, Fair and Poor. Every grade gets a public certificate a buyer can open.

Why GradeThread is the standard

Every grade follows one published method, and every grade has a certificate anyone can check.

Objective

Every garment is scored against one rubric: five weighted factors on a fixed 1.0 to 10.0 scale. Not a subjective, seller-by-seller eyeball judgment.

Published

The factors, their fixed weights, and the seven named tiers are disclosed up front. The rubric is open to inspect, not hidden in a black box.

Consistent

Every garment is checked against the same published standard, with the same five factors and the same weights, no matter who sends it in. Not one seller's eyeball judgment.

Independently verifiable

Every grade becomes a public certificate buyers can open and check, and we publish an open accuracy report, updated as review volume grows.
