Fakespot shut down permanently on July 1, 2025.
It was acquired by Mozilla in 2023 and integrated into Firefox as the Mozilla Review Checker.
Fakespot used AI to detect unreliable reviews on Amazon, eBay, and Walmart with about 90% accuracy.
Studies found that roughly 43% of best-selling Amazon products had unreliable reviews, rising to 88% in clothing and jewelry.
Mozilla discontinued Fakespot due to the inability to sustain its business model.
The closure leaves shoppers without a trusted tool for verifying online reviews.
A new tool called TrueStar is being developed as a spiritual successor to Fakespot.
