About this score: Text Chex uses linguistic statistics — not an AI grader — to assess AI likelihood. Scores measure patterns in sentence uniformity, vocabulary selection, passive voice frequency, and structural markers shown by research to differ between human and AI writing. Use results as one data point, not a final verdict.
