(12 Mar 2026) Over the past week, Grammarly and its parent company Superhuman have been drawing a great deal of unwanted attention to their “Expert Review” feature. Though the feature has been out since August 2025, many of the “experts” have only recently become aware of it and are upset.
The feature is part of their “agent-powered” editor. Though the editor provides the proofreading and plagiarism detection tools it has always had, it added an AI grader, a “reader reactions” agent and more.
However, it’s the expert review feature that has come under the most fire recently. Last week, Miles Klee at Wired wrote an article highlighting the feature, noting that it gives “expert” advice generated by an AI system. However, none of the experts involved gave permission for their names to be used, and many have long since passed away.
Over the next few days, backlash against the feature grew. However, things came to a head yesterday when Grammarly announced it was disabling the feature and launching an option for experts to opt out moving forward.
But even as Grammarly was pressing pause on the feature, journalist Julia Angwin filed a class action lawsuit against Superhuman. The lawsuit alleges that the feature violates the privacy and publicity rights of the various experts included in the product. The lawsuit alleges that the damages to the plaintiff class exceed $5 million.
So what exactly is happening, and what takes place from here? To answer that, we need to first look at the feature itself and understand why it’s become so controversial.
