what this is
covet, wouldcop, and where it's going
Good things are worth waiting for. The problem is that waiting well takes expertise most people don't have: knowing what a thing is really worth, what size you take in a brand you've never worn, and whether the price in front of you is actually good.
covet is the engine that does that work. wouldcop is what it looks like when it's pointed at you.
covet — the engine
covet watches secondhand marketplaces and tries to answer two questions that turn out to be separable:
What is this actually worth?
Every secondhand listing is a unique object, so there's no price tag to look up — only evidence. covet tracks what comparable items have actually sold for, how long things sit before selling, and how often they show up at all. A price is judged against that record, never against a retail sticker.
Would it fit you?
Sizes don't transfer between brands — a large in one is a medium in another, and the gap is worse across eras and countries. Given a few garments you already own and how they fit, covet works out your measurements and predicts your size in brands you've never worn.
These two halves are independent, and we say which one is carrying a given recommendation. A price call doesn't need to know your body; a fit call doesn't need to know the market.
wouldcop — the bots
wouldcop is the buy-side product on top of the engine. It's a fleet of bots on Bluesky, and they're all the same machine with one thing swapped: who the finds are for.
- The public feed — @deals.wouldcop.com filters for nobody in particular. It posts exceptional deals on quality gear, whoever you are. How a deal earns a post →
- A personal bot — filters for one person. Right now that filter is fit: it only surfaces things in your size, in brands you'd wear.
Fit is the first filter, not the whole idea. A bot that only cares about selvedge denim, or a particular era, or one brand's archive, is the same machine with a different filter. That's the direction.
Personal bots are new and currently invite-only, while we find out what they get wrong.
How to make it stop
Unfollow the bot. That's the whole unsubscribe: your bot exists to post to you, so when you stop following it, it deactivates and stops posting. There's no email to unsubscribe from either — we never ask for one, so we don't have one.
What we won't do
- No affiliate links, nothing sponsored. Links go straight to the listing. wouldcop makes nothing if you buy.
- No made-up discounts. Claims are counts against real listings, and every post says which evidence it used. When the evidence is thinner — a size with few recorded sales — the post says that instead of dressing it up as a saving.
- No quiet size claims. If we predicted your size in a brand we can't properly translate, the post says so on its face.
- Your measurements stay put. Body measurements are used to compute your sizes and are not sold, shared, or published. What a personal bot posts is the item — never your numbers.
If promotion ever pays for placement here, it will be labeled as promotion, and it will not change the verdict. A paid item still gets the same price call as anything else, including an unflattering one.
Where it's going
Two directions, neither of them built yet:
- Later A shared vocabulary for resale. The observations covet makes — this item, this price, this market, at this time — are facts other tools could use. Publishing them in an open format is more useful than keeping them.
- Later The sell side. The same engine that tells you what to pay can tell you what to ask, and can help good things reach people who want them instead of going to landfill.
Talk to it
Every bot reads its replies. If a call looks wrong — wrong size, wrong item, a price that doesn't add up — say so in a reply like you would to anything else on your feed. A human reads them, and it's how most of what's been fixed got found.
