A writer is suing Grammarly for turning her and other authors into ‘AI editors’ without consent

Editor's take

Grammarly is facing a class-action lawsuit alleging it repurposed user-written text into training data for its AI features without explicit consent.

This action highlights the ongoing tension between AI tool providers' data needs and users' privacy expectations, particularly for creative professionals whose work forms the bedrock of these models. The suit implicates Grammarly’s business model, which relies heavily on analyzing user input to improve its suggestions, and raises questions about intellectual property rights in the age of generative AI.

Future scrutiny will focus on how Grammarly responds to the legal challenge and whether similar lawsuits emerge against other AI-powered writing assistants like Microsoft Copilot or Google Workspace’s AI features. The outcome could influence user agreements and data privacy policies across the entire AI writing assistance industry.
