Search every secondhand marketplace, get alerted first

Built for people who look every day

More than a list of links to other people's search pages.

Every marketplace, one search

One query goes out to eBay, Vinted, FB Marketplace and the local marketplaces your country actually uses. The same item listed on two of them comes back once.

Alerts that watch while you don’t

Save a search once and it re-runs around the clock. A genuine match reaches you on Telegram or by email the moment it is listed. One alert covers every marketplace, and there is no app to install.

Match check reads every listing

Every result is scored against what you actually asked for, so a search for an iPhone 17 stops returning repair services and cases. Hide the poor matches, or sort by how well each one fits.

Questions, answered

Is keenfind free?

Searching is. Without an account you get a few searches, a free account gets more, and Match check sorts every one. A free account also gets one alert that runs for 48 hours, so you can see an alert work before you pay for one. What costs us money is running alerts around the clock and reaching the two marketplaces that charge us per request, so that is what a paid plan buys.

Which marketplaces do you search?

eBay, Vinted and Facebook Marketplace in every market, plus the local site each country actually uses. Pick a market to see the full list.

How is this different from opening each site myself?

One query fans out to every marketplace at once. The same item listed on three sites is collapsed into one result, everything is sorted together by price, date or distance from your postcode, and results outside your price range are labelled rather than silently dropped.

What does the AI actually do?

Match check reads every listing a search finds (the title and the price) and scores how well it fits what you searched for, so the listings that match come first and the rest are set aside. Alerts use it too: every new listing is scored, and you are only notified about the ones that genuinely match, so a search for a road bike stops sending you children's bikes and bike parts.

How do I get notified about new listings?

By email, by Telegram, or both. There is no app to install, and every notification has a one-click unsubscribe for that specific alert.

Do you sell anything yourself?

No. keenfind only searches and links out to the marketplaces. Every purchase happens on their site, under their terms. We aren't affiliated with any of them.
