What Fakespot does

Fakespot was an AI-powered consumer product review authenticity platform founded in 2016 in New York by Saoud Khalifah and Rob Gross. The company built a browser extension, mobile apps, and a website that analysed online product reviews using natural language processing and anomaly detection to flag fake, manipulated, or inauthentic reviews, helping shoppers identify unreliable product feedback on major e-commerce sites. The technology was differentiated by a privacy-first posture and by integration into the shopping workflow directly within the browser, which led Mozilla to acquire Fakespot in 2023 and rebrand the in-browser functionality as the Firefox Review Checker.

Fakespot operated a freemium product-led growth model distributed through the Chrome Web Store, Firefox Add-ons marketplace, and iOS/Android app stores, serving a long tail of individual online shoppers rather than enterprise customers. No enterprise contracts, pricing tiers, or revenue mechanics were publicly disclosed; the core monetisation path was optional premium features layered on a free extension. The company was venture-backed, with approximately $5.3M disclosed across a 2018 seed round led by SRI Capital and a 2020 round led by Bullpen Capital, supplemented by later undisclosed tranches. Headcount was small (11-50 employees), consistent with a lean consumer utility rather than a scaled SaaS operation.

Mozilla announced on May 22, 2025 that it was phasing out Fakespot because, while the idea resonated with users, the product "didn't fit a model we could sustain." The Firefox Review Checker feature was discontinued on June 10, 2025, and the broader Fakespot extension, mobile apps, and website were shut down on July 1, 2025. The founders subsequently launched Ciphero, an AI security startup, transferring the underlying technical capability to a new venture.

Core offering

Fakespot built and distributed AI-powered consumer tools — a browser extension, iOS/Android mobile apps, and a website — that analyzed the authenticity of online product reviews on e-commerce platforms and flagged fake, manipulated, or unreliable content. The technology used natural language processing and anomaly detection with a privacy-first approach, and was embedded into the Firefox browser as the Review Checker feature following Mozilla's 2023 acquisition. The entire product line was shut down on July 1, 2025.

Product overview

Fakespot was a unified product suite consisting of a browser extension, mobile apps, and website that analyzed online product reviews for authenticity using AI. The product portfolio was unified under the Fakespot brand, with the core offering being the browser extension that scanned and scored reviews to detect fake or manipulated content. Mozilla integrated Fakespot technology directly into Firefox as 'Review Checker'. The company was acquired by Mozilla in 2023 and the entire product line was shut down on July 1, 2025.
