Mozilla has announced the acquisition of Fakespot, a tool that uses AI to detect fake reviews on e-commerce sites like Amazon, eBay, Sephora, and Shopify. Fakespot will be integrated into Firefox over time, and Mozilla hopes to expand its work on the ethical use of AI and responsible use of advertising. The Chrome, iOS, and Android versions of Fakespot will continue, and Mozilla will improve the Fakespot experience for all users. In the future, there will be a unique integration of Fakespot with Firefox, which will help users become better prepared to identify fake reviews. Fakespot uses AI to analyze product reviews and look for signs of paid, fabricated, and deceptive behavior. The developers do not disclose their working methods to prevent scammers from evading detection.
