You find products, niches and keywords on Amazon with data instead of guesses. Four verified tools compared on price, free option and data limits.
Amazon sellers use research tools to judge demand, competition and margin before they commit to inventory. Four tools from our verified catalogue cover different parts. SellerSprite combines niche, keyword and listing research with margin modelling. SmartScout offers databases of brands and sellers. Sellerise bundles profit tracking, reviews and keyword research. Koala Apps is a Chrome extension for Shopify competitor research, so it helps with store research rather than Amazon itself. Prices start at $22 to $49 a month. None has a permanent free plan for Amazon research, though SellerSprite gives a 3-day trial and Koala has a small free tier. Data accuracy is not tested here.
