Grammarly has launched an AI feature called "Expert Review," claiming it can optimize user writing through the perspectives of renowned writers and thinkers. Integrated into the Writing Assistant sidebar, the suggested edits often adopt specific personas, including both living and deceased famous authors as well as journalists from tech media outlets such as The Verge and The Wall Street Journal. User testing revealed that some generated suggestions even cited specific journalist names like Casey Newton or Timnit Gebru, yet omitted figures from publications like TechCrunch, sparking external confusion. In fact, none of these quoted "experts" participated in developing this feature nor authorized Grammarly to use their names. Alex Gay, Vice President of Product at Grammarly's parent company Superhuman, stated that these individuals were referenced solely because their publicly published works have been widely cited. The software user guide explicitly clarifies that related citations are provided for informational purposes only and do not imply any affiliation between the named individuals and Grammarly, nor constitute endorsement by them. Although Grammarly attempts to lend authority to its recommendations, many critics argue that the feature lacks genuine expert involvement and essentially does not qualify as "expert review." Historian C.E.O'Brien bluntly noted that since no actual experts contributed to generating the content, labeling it "expert review" is misleading. This controversy highlights ethical and authenticity challenges currently facing generative AI in content creation: When AI mimics celebrity tones without obtaining real authorization, the credibility and transparency of its suggestions warrant serious reflection.
