What ByeThings does, how the AI works, and what it will not do
Last updated 28 July 2026
What this is for
Most things people mean to sell never get sold. Not because nobody wants them, but because listing something is tedious: photographing it, working out what it is worth, writing a description that makes somebody drive across town for it.
ByeThings removes that. You photograph the thing. The app works out what it is, what condition it is in and what it is worth, and writes the listing. You check it, set your price and publish.
How the scanner works
Your photo is reduced to a size the model can read accurately, then sent to a specialist AI provider along with anything you typed about the item. It identifies what is in the shot, judges the condition from what it can see, and estimates a price range.
That estimate is not checked against any other marketplace. Nothing is sent to a third-party pricing service, and no figure here reflects what a similar item sold for elsewhere.
The photograph is used to answer your request and is not used to train anyone's model.
What the estimate is, and is not
It is a starting point, produced by a machine that has seen one photograph. It is good at recognising an ordinary object in a clear shot, and it is worse at telling a genuine piece from a convincing copy, or at reading a model number that is not in frame.
It is not a valuation, an appraisal or advice. Do not use it for insurance, probate, a dispute or anything else where being wrong has consequences.
You always see the estimate before you are asked for anything, and the price you publish is the one you choose.
The marketplace
Published listings appear to other people nearby, ordered by roughly how far away they are. Distance is approximate by design — worked out from the outward part of a postcode, accurate to about a mile — because that is the resolution a public listing should expose about where somebody lives.
A listing shows the item, the price, the condition and the general area. It never shows a full postcode, an address or a phone number.
Messaging
Buyers and sellers talk in the app, which means neither has to hand over a phone number or an email address to ask whether something is still available.
Both people need an account. That is the point: a marketplace where one side is anonymous is one where only one side is accountable.
Offers are made and answered in the conversation, so what was agreed is written down rather than remembered.
Accounts and what they are for
Everything here needs an account: scanning, listing, selling, buying and messaging.
For most of those it is because a second person is involved, and they deserve somebody accountable at the other end. For scanning it is simpler — every scan costs us real money to run, and an account is what ties that cost to somebody rather than to nobody.
Making one is free, takes a moment, and comes with scans included.
What we do not do
We do not sell your data, show you advertising, or track you anywhere else.
We do not take a cut of your sale or handle the money between you and a buyer.
We do not vet users or inspect items. Please read the safety guidance in the Terms and Conditions before arranging to meet anyone.
