Grammarly disabled its Expert Review feature that generated AI feedback impersonating real writers and academics. Superhuman CEO Shishir Mehrotra announced the decision on March 11, 2026, stating the company will reassess the feature.
The suspension addresses a class action lawsuit filed against Superhuman by living writers who discovered their names were used without permission. The feature used publicly available information from third-party LLMs to create writing feedback attributed to specific individuals.
Grammarly launched Expert Review in August to provide AI-generated writing suggestions credited to famous authors and academics. The feature selected experts based on subject matter without obtaining permission or knowledge from the individuals. Living writers expressed displeasure upon discovering the attribution.
The company included a disclaimer stating references were for informational purposes only and did not indicate affiliation or endorsement. Superhuman initially responded by allowing writers to opt out of the platform. Mehrotra stated the feature was designed to help users discover influential perspectives.
Mehrotra wrote on LinkedIn that the agent was designed to provide meaningful ways for experts to build deeper relationships with their fans. The class action lawsuit is pending against Superhuman regarding the feature. Superhuman owns Grammarly.
