Find profitable Vinted niches before saturation

Price coherence measures how tightly the listings in a niche cluster around a median price without scattering. On Vinted, a coherent niche shows a narrow spread between the 25th and 75th percentile: most items sell within a tight band, which signals a readable market with a predictable resale price. Nichify computes this signal on every cluster of items it detects, trimming extreme values so a niche is not penalised by a few outlier listings. The higher the coherence, the more exploitable the niche: you can set a buy price and a resale price without depending on luck. Low coherence, on the contrary, reveals a fragmented segment where each seller applies their own pricing and where sourcing becomes guesswork.

Niche detection automatically identifies groups of items that form a coherent sub-market inside a Vinted catalogue. Nichify scans the listings in a category, brand or keyword, then clusters items sharing the same attributes: title, model, variant, price band. Each cluster becomes a niche candidate that the algorithm evaluates on four dimensions: active listing volume, median price, price coherence and publication history. Clusters that pass all four thresholds receive a score between 0 and 100 and are ranked from most to least exploitable. This approach removes the trial-and-error of manual search: instead of testing one keyword after another, you receive in a single analysis the list of profitable sub-markets, their reference prices, and the leads close to the threshold worth watching.
