Investigation Finds Grammarly’s ’Expert Review’ Is Largely Automated, Not Human

An investigation into Grammarly’s premium ’expert review’ feature concludes the service relies predominantly on advanced machine-learning models rather than human editors. Analysts and user reports point to instantaneous response times and highly consistent feedback patterns that resemble automated NLP-driven suggestions. Technical analysis indicates the feature builds on Grammarly’s existing natural language processing stack to deliver grammar, style, tone and clarity improvements, but lacks the variability and contextual nuance typical of human editorial review. Industry experts and ethicists call for clearer transparency and labeling of AI-driven services. Comparative studies show AI tools handle technical errors well but underperform on voice, rhetorical effectiveness and creative insight compared with human editors. The finding has prompted calls from professional editing associations for certification and clearer disclosure. For writers and businesses, the feature remains useful for technical and business documents, but important creative or high-stakes work should still be supplemented with human review.
