QuillBot AI Content Detector analyzes text to estimate the likelihood that it was written by AI or a human. It does not flag individual words but looks at writing patterns like repetition, generic language, and lack of tone variation. The tool works by measuring perplexity (predictability) and burstiness (sentence length variation). It supports multiple languages and provides detailed feedback on which parts of the text appear AI-generated, AI-refined, or human-written. QuillBot’s AI detector helps educators, writers, and content creators verify originality and understand AI’s role in the writing process.
