Usage Examples
Example 1: Detecting AI-Generated Essay
Input Text:
"Artificial intelligence represents a paradigm shift in technological innovation, fundamentally transforming how we interact with computational systems and process information. The integration of machine learning algorithms has enabled unprecedented capabilities in data analysis and pattern recognition."
Detection Result:
85% AI-generated - High probability of AI content. Indicators: Formal structure, technical terminology, lack of personal voice.
Example 2: Human-Written Content
Input Text:
"I've been working with AI tools for about three years now, and honestly, they're pretty amazing. But here's the thing - they're not perfect. Sometimes they miss the nuance that makes writing feel real, you know?"
Detection Result:
15% AI-generated - Likely human-written. Indicators: Conversational tone, personal pronouns, natural flow, informal expressions.
Example 3: Mixed Content Detection
Input Text:
"The research methodology employed in this study utilized a comprehensive approach to data collection. We interviewed 50 participants and found some really interesting stuff that surprised us. The results indicate significant correlations between variables."
Detection Result:
60% AI-generated - Mixed content. Some sections appear AI-generated (formal academic language) while others show human writing (casual expressions, personal observations).
Best Practices for AI Detection
Use Sufficient Text Length
For best results, analyze texts of at least 200 words. Longer texts provide more linguistic patterns for analysis, resulting in higher accuracy. Very short texts (under 50 characters) may produce less reliable results.
Analyze Complete Context
Include full paragraphs and complete thoughts rather than isolated sentences. Context helps the detector analyze writing patterns, flow, and consistency throughout the text.
Consider Multiple Factors
Don't rely solely on detection scores. Consider the context, writing style, and purpose of the text. Some highly formal or technical writing may naturally score higher, while creative or personal writing typically scores lower.
Review Detailed Indicators
Pay attention to the specific indicators provided (sentence structure, word choice, consistency). These help you understand why the text was flagged and make informed decisions.
Use as One Tool Among Many
Combine AI detection with other assessment methods like writing style analysis, knowledge checks, and personal interaction. Detection tools are most effective when used as part of a comprehensive evaluation approach.
Understand Limitations
Be aware that highly edited or rewritten AI content may be harder to detect. Paraphrased content, heavily revised text, or content written by newer AI models may produce different detection scores.
