What is it worth?

Start with the object in front of you

A chair from a house clearance. A jug with an unfamiliar maker’s mark. A box of books you are deciding whether to keep. A photo gives you a starting point without asking you to know the name first. Upload a clear picture of the main object, then check the identification before taking the suggested range seriously.

The photo tool uses a vision model hosted by Cloudflare Workers AI. The model accepts images as well as text.¹ It looks for features such as shape, material, construction and readable product markings. Its answer includes the object it thinks it sees, the clues behind that identification and the details it cannot establish from the picture. The range is an AI estimate for US second-hand resale in US dollars. It is not a completed sale, a buyer’s offer or a professional appraisal.

Better details make a more useful estimate

Photograph one object at a time in even light. Show the whole item rather than only its most interesting corner. A sharp picture of a maker’s mark or model label can help, but leave personal documents, addresses and people out of the frame. If the first photo misses an important feature, start a new estimate with a better view.

After the first result, add facts you know: dimensions, whether it works, missing parts, repairs or a confirmed brand. You can correct the condition and ask the model to update its estimate. A worn item and a complete working example may attract different buyers, even when they look alike in a photo. Unknown condition remains an assumption to check; the tool cannot test electronics, identify every material or inspect hidden damage.

Some objects need a closer look than a photograph permits. An unmarked ceramic, a signed work of art or a piece of jewelry may need authentication or specialist inspection. When the identification is weak, the useful answer may be a question rather than a price. Do not treat a confident-sounding description as proof of age, maker or authenticity.

Your photo stays private unless you share it

Uploading sends the picture to our server for processing and AI analysis. We remove embedded metadata and blur detected faces before sending an analysis image to Cloudflare. Product markings may remain visible so the model can identify the object. For standard stateless inference, Cloudflare discards inputs and outputs after processing and response delivery, subject to limited legal exceptions.² Cloudflare says it does not use this content to train AI models.³ Detection is imperfect, so choose a photo without sensitive details. Read the privacy page for how the service handles stored previews, results and removal links.

The original image is not stored. A sanitized preview and its result are kept privately for a limited time so you can inspect them. Sharing is optional: review the preview, cover any remaining identifying details and explicitly choose to publish. No email address or account is needed for an estimate. Email updates are a separate choice.

Check the purpose of every number

Use an AI range to decide what to investigate next. Before setting an asking price, check the object’s identity and condition, then look for comparable completed transactions in the market where you intend to sell. A listing’s asking price alone does not tell you whether a buyer paid it. Location, delivery costs and the time you are willing to wait can change what a sale returns.

Donation research is still available in the donation value calculator and donation value guides compared. Those pages keep each charity’s published range separate. Government surplus observations, when a suitable set is available, are labelled as last observed high bids. Neither source is silently substituted for the AI estimate. methodology explains these differences; sources records where the evidence comes from.
