Decopy AI — AI for Writing, Translation & Localization

As AI-generated text becomes more common, knowing the origin of a piece of writing is increasingly difficult. Decopy AI provides a direct way to address this uncertainty. You can copy and paste any text into its analyzer, and it will return a percentage score that estimates the probability of it being AI-generated. The tool works by looking for statistical patterns, predictability, and other linguistic markers that are often present in the output of large language models. It is designed for anyone who needs to verify the authenticity of written work, such as educators checking student submissions, editors reviewing freelance articles, or content managers auditing website copy. It's important to understand that this is a probabilistic tool. A high score is not definitive proof of AI use, and false positives are a documented issue, especially for people writing in a second language or in a highly structured style. The score is a single data point, not a final verdict, and should never be the sole basis for accusing anyone of misconduct. Think of it as a first-pass check, not an infallible truth machine.
