How to Detect Text Generated by ChatGPT

ChatGPT is one of the most popular language models, developed by OpenAI and used by millions of people. But how can you identify text generated by it?

Signs that a text may have been generated by ChatGPT

1. Overly perfect language: AI texts rarely contain grammatical or spelling errors
2. Repetitive structure: Paragraphs follow a predictable pattern (introduction, development, conclusion)
3. Lack of personal opinions: AI avoids strongly subjective expressions
4. Padding phrases: Expressions like "it is important to mention", "in conclusion", "however"
5. Lack of cultural nuance: Generic references without local specificity

Verification techniques

• Use an AI detection tool such as AiDetector (free) or Originality.ai (professional)
• Check stylistic consistency: A human author has a variable style
• Look for sources and references: AI texts rarely cite real sources
• Ask follow-up questions: A human author can elaborate; AI will generate a new text

Limitations

No tool is 100% accurate. Short texts are harder to analyse, and texts edited by a human after AI generation may "fool" detectors. Use multiple tools for a complete check.
