Scribbr AI Detector helps check if a text is written by AI or a human. It can tell if a piece of writing is fully AI-generated, AI-refined, or purely human-written. The tool gives clear feedback at the paragraph level and supports multiple languages including English, German, French, and Spanish. It uses machine learning to analyze sentence structure, wording, and style, flagging parts likely produced by AI. Scribbr works well for educators, students, and writers needing to ensure originality. However, it may miss AI-edited writing or misclassify some human text. It’s easy to use and trusted for basic AI detection.
