This tool estimates whether writing may sound AI-generated. It is not a final academic, legal, or disciplinary judgment. Results reflect linguistic patterns, not proof of authorship.
AI detection tools analyze patterns in language — sentence uniformity, predictable transitions, generic vocabulary, and repetitive rhythm. These patterns correlate with how language models generate text. But they are statistical estimates, not certainties. Any detection system will produce false positives and false negatives.
Written's approach is different. Instead of issuing a verdict, it shows you why your text might score as AI-generated and gives specific, actionable suggestions to improve your natural voice.

Written's AI detector is designed as a writing feedback tool, not a policing system. Use it to understand what aspects of your writing feel generic, robotic, or formulaic — then use the Humanizer or AI Influence Slider to address those specific areas.
If you're a student, educator, or professional, please use this tool as part of a writing improvement workflow — not as evidence in any disciplinary, academic, or legal setting.
AI detection scores are statistical estimates based on language patterns. Written does not claim these scores represent definitive proof of AI authorship. Results should not be used for academic integrity decisions, legal proceedings, or employment determinations.
