Our Gemini-powered engine analyzes multiple linguistic signals to distinguish AI-generated text from human writing.
AI text often shows unnaturally uniform sentence lengths, repetitive transition phrases ("Furthermore", "Additionally"), and overly parallel structures that humans rarely maintain consistently.
Human writing is naturally unpredictable — we pick unexpected words, make minor errors, and take creative detours. AI text is statistically predictable, always choosing the most likely next word.
Humans include personal anecdotes, specific details, and emotional nuance. AI tends to be generically helpful, balanced, and avoids strong personal opinions or highly specific lived experience.
Important: No AI detector is 100% accurate. Results are probabilistic estimates based on linguistic patterns. Highly edited AI text, or very formal human writing, may score unexpectedly. Use this as one signal among many, not as definitive proof.
