AmzChart vs AppTweak

AmzChart is a product research tool for Amazon sellers, available on the web and as a browser extension. Sellers can search by keyword, brand, or ASIN and filter products using measures such as BSR, review count, and rating. Market search applies those inputs to identify relevant departments and return market insights. Keyword Scout uses reverse ASIN lookup to investigate competitors’ keywords, including long-tail terms for listings. AmzChart says it tracks product performance and can alert users to listing hijacking events or changes; sellers can also save named search filters for later use. Its listed marketplaces include the US, Japan, India, Germany, France, Spain, the United Arab Emirates, the UK, and Mexico. The FAQ says its commodity database contains more than 50 million commodities and is updated daily, with over 9 million daily updates. The browser extension’s Price History Tracker shows historical and lowest prices across 11 listed Amazon locales and does not require an account. The Free Plan costs nothing and includes five daily product searches, five daily product refreshes, and the US marketplace.
