Detected as AI? Rewrite this text to read as human-written — meaning preserved, AI tells removed.
How accurate is this? No AI detector is 100% reliable. This tool combines statistical signals (burstiness, lexical patterns, structural uniformity, model-specific phrase tells) and attributes likely source by matching against curated phrase libraries for ChatGPT, Claude, Gemini, and generic LLM patterns. Use the result as a hint, not a verdict — heavily edited AI text, short samples, or modern LLM output that's evolved past these signatures may be misclassified. If you're a non-native English speaker, enable ESL-safe mode above to reduce false positives.
