How a number gets on this site

Photo identification and AI estimates

Upload a photo and the vision model identifies the main object from visible features. You can add condition, dimensions, a known model or other details and ask for an updated estimate. The result records the provider, exact model, prompt version and generation time. An identification-confidence label concerns what the object is; it is not a measured probability that the price is correct.

An AI estimate is a model-generated range for US second-hand resale in US dollars. It comes with visible details, assumptions and questions about missing information. The model does not search live marketplaces or retrieve comparable completed sales. Its training can be incomplete or out of date. An estimate is not a buyer’s offer, authenticated identification, professional appraisal or donation deduction. If the photo does not support a useful identification, the result asks for more detail without printing a range.

The current model is Gemma, hosted by Cloudflare Workers AI. The model accepts images as well as text.¹ Metadata and detected faces are removed or blurred before inference. Product markings can remain readable to help identification. The original is processed in memory and is not saved. A separate stored preview has detected text blurred too. Reviewing that preview and choosing to publish are separate from receiving a private estimate.

Published evidence has a different meaning

A guide range is one charity's low and high for one item type. The row label stays as that guide printed it, including a slash or an odd plural. Dated guides sort newest first. An undated guide sorts last. The Salvation Army national list is the undated one. Retrieved 2026-11-12. On a category page the columns follow that order, and an empty cell says not listed. It is not filled from another guide. donation value guides compared compares the lists. One range at a time is also how prose is allowed to mention a price: $36–$207² is the sofa row on that list, not a site-wide sofa value.

The rule estimate is separate from every guide total. Goodwill Northern New England publishes 30%³ of the original price for an item not on their list. The calculator applies that percent to a price you type for an item that is not an item type. It labels the line as the rule. It never adds those dollars into a guide's low or high. Rows from that guide are not on this site. The privacy page says reproduction of material there needs prior permission, so the guide is a link and that one sentence.

An observation set is government surplus, not a donation range. The channel line, when the page exists, is US government surplus auction (as-is, buyer pickup). The number in a row is the last observed high bid divided by the unit quantity stated on the lot. A weight, a length, an area, a volume or a count of hours does not count as a quantity. A table needs at least three matched lots. A median line waits until the set has twenty lots. A later retraction drops the lot. The same lot ended twice counts once. surplus auction prices holds that method in full, and the route stays off until a matched set qualifies. The words in a surplus section do not call a bid a completed sale.

A fact is everything else that has a URL, a quote, a retrieval date and a unit. Dollars, percents, dates and sentences all go through the same footnote. $500⁴ is the Publication 526 noncash total, not a number typed into the code. Text facts print the quoted sentence. Household items include furniture, furnishings, electronics, appliances, linens, and similar items.⁵ is one of those. The build fails a fact that has no source. Content files cannot sneak a bare dollar, a bare percent or a large integer past the placeholder. Years, a few small integers, and citations such as Form 8283 and Publication 561 are the exceptions.

What this site does not do: blend two guides into one span, treat a guide range as money that changed hands, reprint one guide's priced table as its own page, or scrape a retailer. Asking prices are not evidence. A model-generated range is labelled as an AI estimate and is kept separate from these evidence records. Community contributors can publish a reviewed photo and its AI result, with that distinction visible.

Dates a reader sees use the New York calendar day. The sitemap date is the build date in that zone. Condition classes are this catalog's filing: household and clothing honor the below-good switch, other does not, excluded adds nothing. Household items do not include paintings, antiques, objects of art, jewelry, gems, and collections like stamp and coin collections.⁶ is why antiques, art, jewelry, gems and collections are excluded. One copied list still prices a picture, and that row is in the excluded class, so it adds nothing. Building materials are other. A generator has a surplus match rule and no guide row, so it can appear as lots without ever appearing as a donation range.

The donation calculator runs the guide totals. home starts photo identification. IRS rules for donated household items quotes the thresholds the notices use. sources is the retrieval list. A category hub such as Furniture is the table for that group.
