AI Content Detector Free Online
Check if your text was written by AI or a human with our advanced detection tool
About Our AI Content Detector
Our free AI Content Detector tool helps you identify whether a piece of text was written by a human or generated by artificial intelligence (AI) tools like ChatGPT, GPT-4, Bard, and other large language models.
How It Works
The tool analyzes various characteristics of the text including:
- Perplexity: Measures how predictable the text is (AI tends to be more predictable)
- Burstiness: Evaluates variation in sentence structure and length
- Semantic Patterns: Identifies common AI-generated phrasing
- Stylistic Features: Analyzes word choice and sentence construction
Why Use an AI Detector?
With the rise of AI writing tools, it's becoming increasingly important to:
- Ensure academic integrity in schools and universities
- Maintain authentic human content on websites and blogs
- Verify the originality of submitted work
- Check marketing content for AI-generated material
Understanding Your Results
The tool provides a percentage score indicating the likelihood that the content was AI-generated. Here's how to interpret the results:
- 0-30% AI: Very likely human-written
- 31-60% AI: Possibly mixed human/AI content
- 61-90% AI: Likely AI-generated with some human editing
- 91-100% AI: Almost certainly AI-generated
Accuracy Considerations
While our tool is highly accurate, consider these factors:
- Short texts (under 150 words) are harder to analyze accurately
- Highly technical or formulaic writing may score as more "AI-like"
- Human-edited AI content may fall in the middle range
- Newer AI models are constantly improving and may be harder to detect
Frequently Asked Questions
Is this tool completely free?
Yes, our basic AI detection is completely free to use without any limits.
How long does the analysis take?
Typically 5-15 seconds depending on text length and server load.
Do you store the text I analyze?
No, we analyze your text in real-time but don't store it permanently.
Can the tool detect all AI models?
We detect most major models (ChatGPT, GPT-4, Bard, etc.) but new models may require updates.
Tips for Creating Authentic Content
If you want to ensure your content reads as human-written:
- Write from personal experience
- Include specific examples and anecdotes
- Vary your sentence structure and length
- Use natural, conversational language
- Add personal opinions and unique insights
