How it works

List your second-hand items online in seconds

Using a combination of CNNs (convolutional neural networks) and LLMs, Rummij is able to isolate and identify up to 100 items from a single picture.

No more debating whether to invest time and effort listing your spare books or video games; a single picture is enough to get an entire bookshelf online in less than a minute.

Speed in simplicity.

Rummij is super-simple to use: take a picture; check the automatic AI listings; click accept. Rummij handles the text, photos, postage calculations and even some guide prices.
