Market Memory remembers what an OLX offer used to cost.
Open any offer on olx.pl and a small card appears next to the price showing that listing's own history: what it cost when it was first seen, every price change since, how far it sits above its lowest point, and a sparkline of the whole run. On a search or category page, listings that already have a tracked history get a compact badge, so a price that has been quietly climbing is obvious before you click.
WHAT IT SHOWS
• Price history for an individual offer — first seen, every change, current, lowest, highest
• A badge on search and category results for listings with a known history
• Title changes, and a marker when the seller edited the description
• Offers that disappeared from your followed list, and when they went
• Free ("Za darmo") and exchange ("Zamiana") listings, not just amounts
• Followed offers that live on OLX's sister sites (otomoto.pl for cars, otodom.pl for property) are recognised from your followed list, so they are not mistaken for removed
HOW IT WORKS
Prices are shared. When you open an offer, the extension records what it sees and contributes it to a common history, which is why an offer you are meeting for the first time can still show you moves that other people's browsers recorded before you arrived. There is no account and no sign-up — contributions are tagged with a random identifier generated on your device.
WHAT IT DOES NOT DO
It runs on olx.pl and nowhere else. It reads no other site, collects no name, email, or address, and never transmits listing description text — only a short non-reversible hash of it, so the shared timeline can note that a description was edited without the words ever leaving your device. Nothing is sold. Full detail: https://market-memory-ext.vercel.app/privacy
Have data about a listing removed: https://market-memory-ext.vercel.app/takedown
The extension's in-page interface is in Polish.
Market Memory is an independent project. It is not affiliated with, endorsed by, or sponsored by OLX, and uses no OLX branding.
