Colleges do check for AI in application essays. Many admissions offices use AI detection tools that analyze linguistic patterns, vocabulary, sentence structure, and writing style to identify likely AI-generated content. They combine this technology with human review to assess the authenticity of essays. Some elite universities have explicit policies banning AI-written essays as violations of academic integrity. Admissions officers look for personal insight, unique anecdotes, and emotional depth—attributes that AI- generated text generally lacks. If an essay is flagged by AI detection software, schools often follow up with additional writing samples or interviews to verify authenticity. The use of AI detectors is increasing across colleges, though detection methods and policies vary by institution.
