Understand if text was generated by a GPT with this free AI checker tool.
Accurate AI Writing Detector
Our free AI detector identifies repetitive patterns and spots overused AI phrases and grammatical constructs, so you can determine if text was generated by artificial intelligence with confidence.
Detect Text Generated by Multiple AI Models
This ai detector tool can recognize text generated by ChatGPT, GPT-4, GPT-5 Claude, Gemini, and other popular AI models by analyzing their distinct writing patterns and characteristics.
AI Detection Confidence Score
Get percentage ratings showing the likelihood that your text is AI-generated, with detailed scoring based on multiple detection algorithms and pattern recognition. Zero percent means the text is 100% human, while 100% means it's definitely AI-generated.
Detailed ChatGPT AI Detector Insights
See exactly which phrases, sentence structures, and word patterns triggered AI detection alerts, with explanations for why each element suggests artificial generation.
Overchat AI brings you the power of the world’s top AI models: ChatGPT, Claude, Gemini, Mistral, and more.

What is an AI detector?
A detector is a tool that analyzes text using artificial intelligence to identify if it was generated by a GPT like ChatGPT, Claude, or Gemini.
What is the best AI detector?
Overchat's AI detector is very accurate because we continuously retrain our models on new AI outputs and emerging language patterns to stay current with evolving AI capabilities.
How does an AI detector work?
An AI detector learns from examples of human and AI writing, then measures things like text predictability, word choice patterns, and sentence structures to spot artificial generation.
How to get past an AI detector?
Mix up sentence lengths, add personal style, use contractions, and remove repetitive phrases that AI models commonly produce to avoid detection patterns.
How accurate is Overchat AI detector?
Overchat AI detector works well because we analyze perplexity patterns, word probability distributions, and sentence structures that different AI models produce.
What is the best free AI detector?
Overchat AI detector gives you 5 free checks with no signup required, and it uses the same detection technology as paid tools.
