AI-generated ‘Expert Reviews’ were not successful with users or subject matter experts. Grammarly’s rebranding as “Superhuman” marked a shift towards AI-driven features. Their controversial “Expert Review” feature, introduced in August 2025, used AI to generate writing suggestions under the names of well-known authors and experts, but without their consent or endorsement. The feature went unnoticed until March 2026 when reports emerged of it using names like Stephen King and Neil deGrasse Tyson. The Expert Review was disabled following backlash and a class action lawsuit against Superhuman, alleging privacy and publicity rights violations. Despite the setback, Superhuman expressed intentions to reimagine and potentially relaunch the feature, aiming to involve experts in its development. The incident highlights concerns over the use of AI in generating content and the ethical implications of using real individuals’ names without permission.
