Grammarly AI Sued for Impersonating Writers
12 Mar
Summary
- Grammarly's 'Expert Review' feature mimicked real writers without consent.
- A class-action lawsuit was filed against Grammarly's parent company.
- The lawsuit seeks to stop Grammarly from using authors' names without permission.
Grammarly has permanently turned off its "Expert Review" feature after facing significant backlash and a class-action lawsuit. This controversial tool generated writing suggestions that mimicked the distinct styles of renowned journalists, authors, and academics without obtaining their explicit consent.
The feature, which launched in August 2025, was found to be using the writing styles of numerous professionals, including those from publications like Bloomberg and IGN. Investigative journalist Julia Angwin initiated a class-action lawsuit against Grammarly's parent company, Superhuman, on Thursday. The suit contends that Grammarly misappropriated individuals' names and identities for commercial purposes, violating New York and California laws.
The legal case demands a court order to halt Grammarly's use of these individuals' identities without permission. Angwin stated she is pursuing the action on behalf of all individuals who have dedicated years to refining their craft, only to be impersonated by AI. A Superhuman spokesperson acknowledged the feature missed the mark and apologized for the misstep, promising future changes.
