Superhuman, the company behind writing tool Grammarly, has disabled its Expert Review feature following complaints and a class action lawsuit. The tool used AI to generate writing feedback attributed to famous authors and academics without their consent. CEO Shishir Mehrotra announced the shutdown on March 11, 2026.
Superhuman launched the Expert Review feature for Grammarly in August, allowing users to receive AI-generated feedback on their writing that appeared to come from notable figures such as scientific minds, bestselling fiction authors, and tech bloggers. These suggestions were based on "publicly available information from third-party LLMs," according to the company. The feature included experts both living and deceased, with their names displayed without permission or knowledge.
Grammarly included a disclaimer stating, "References to experts in this product are for informational purposes only and do not indicate any affiliation with Grammarly or endorsement by those individuals or entities."
The tool drew criticism from living writers, leading to an attempted class action lawsuit against Superhuman. In response, the company initially offered an opt-out option for affected individuals. However, on March 11, 2026, Superhuman CEO Shishir Mehrotra announced via LinkedIn that the feature would be disabled while the company reassesses it.
Mehrotra explained, "The agent was designed to help users discover influential perspectives and scholarship relevant to their work, while also providing meaningful ways for experts to build deeper relationships with their fans."
The class action lawsuit, confirmed as pending, alleges unauthorized use of the experts' names in the AI tool. Superhuman has not provided further details on the reassessment process or timeline for potential relaunch.
