Frequently Asked Questions
How does AI text detection work?
AI text detection works by analyzing writing patterns that are characteristic of AI-generated text. These include predictable sentence structures, limited vocabulary variation, and consistent stylistic patterns that differ from natural human writing.
Can AI text detectors be wrong?
Yes, AI detection results are probabilistic assessments, not absolute determinations. Factors like text length, topic, and writing style can influence results. We recommend using detection scores as guidance, not definitive proof.
What's the minimum text length for reliable detection?
While our detector works with any text length, we recommend at least 50 words for reliable results. Longer texts provide more patterns for analysis, leading to higher confidence scores.
Does editing AI text affect detection?
Minor edits to AI text typically don't significantly change detection results. However, substantial rewriting that introduces natural human variation can affect scores. Our text humanizer can help improve AI text quality.
Is this AI text detector accurate?
Our AI text detector achieves high accuracy by combining multiple detection engines. It reliably identifies text from major AI models including ChatGPT, Claude, and Gemini. However, no detector is 100% accurate in all cases.
