The query is stemmed into Polish product words and matched against product titles across the index — the product type up to the first preposition, so “case for iPhone” finds cases, not iPhones.
Product Research finds Allegro products similar to the one you want to sell, measures the market around them — revenue, sellers, prices, competition — and says how hard entry looks. In plain words, with the numbers next to the answer.
Product Research says whether the market pays for a newcomer — and at what price — before you order samples, pay for photos and lock money in stock. Ten reports cost less than one wrong SKU.
One field. Describe the product the way a buyer would search for it. Marzi turns the phrase into Polish product stems and finds the Allegro product cards whose titles match — the product type, not a category guess.

The similar products are read from the index: how much they turn over, how many sellers share them, where the price sits and how crowded the head is. Each measure is scored against the distribution of the whole index, so “high” means high for Allegro, not for this list.

Marzi's assessment states whether the opportunity is worth pursuing and why — with a score, entry accessibility, and how confident the answer is. If the list includes products that are not yours, remove them and the verdict is recomputed.

The product, in plain words: “wireless earbuds”, “etui na telefon”, “garden hose 30 m”. Marzi works from the product type, so the shorter and more concrete the phrase, the better the match.
