Identify AI-generated text from ChatGPT, GPT-4, Gemini, Claude and other AI tools.
Our advanced AI detection technology analyzes linguistic patterns, structural signals, and probabilistic signatures to determine whether text was written by a human or generated by artificial intelligence.
AI writing tools have transformed content creation. However, submitting AI-generated work as original undermines learning, academic integrity, and fair assessment.
Detects repetitive structures, predictable vocabulary, and generic phrasing common in AI outputs.
Measures how predictable text is. AI writing typically shows lower variability in word selection.
Analyzes variation in sentence length and complexity. Human writing shows natural fluctuation.
Identifies unique stylistic signatures of AI models like GPT, Gemini, and Claude.
Evaluates whether text demonstrates genuine human insight or remains surface-level and generic.
Likely human-written
Mixed or uncertain content
Likely AI-generated
Each sentence is color-coded to show AI probability and highlight suspicious sections.
We explain why content appears AI-generated, including detected patterns and stylistic markers.
AI detection is highly accurate (~96%) but not perfect. It should support academic decisions—not replace human judgment.
