How AI Content Detection Works
Our AI Content Detector uses advanced linguistic analysis to evaluate text for patterns typical of artificial intelligence. While no detector is 100% perfect, our tool analyzes several key indicators to provide a comprehensive probability score.
Key Metrics We Analyze
-
Predictability (Perplexity): This measures how "surprising" the text is. AI models are trained to predict the next word, so they tend to generate text that is mathematically probable and "safe." Human writing often uses unexpected words or phrasiology, resulting in lower predictability scores.
-
Structure Uniformity (Burstiness): This measures the variation in sentence structure and length. Humans tend to write with "bursts" of creativity—mixing short, punchy sentences with longer, complex clauses. AI models often generate text with very uniform, robotic rhythm.
-
Pattern Repetition: AI models frequently overuse certain transitional phrases (e.g., "in conclusion," "delve into") and generic hedging language.
Understanding Your Score
- 0-20% (Likely Human): The text exhibits high variance and unpredictability, strongly suggesting human authorship.
- 21-50% (Mixed): The text may be human-written but polished, or a mix of human and AI content (e.g., AI-assisted editing).
- 51-100% (Likely AI): The text demonstrates high predictability and uniform structure, characteristic of raw AI generation.
Tips for Humanizing Content
If your content is being flagged as AI, try:
- Varying your sentence lengths: impractically short sentences followed by longer, descriptive ones.
- Using specific examples: AI often speaks in generalities. Add personal anecdotes or specific data.
- Avoiding generic transitions: Remove phrases like "it is important to note" or "furthermore."
- Injecting opinion: AI is neutral. Human writing often carries a perspective or voice.
Frequently Asked Questions
Is this AI detector accurate?
Our detector provides a probabilistic assessment based on linguistic patterns. While highly effective for widely available models like GPT-4 and Claude, it should be used as a guide rather than absolute proof. False positives can occur with highly formal, technical, or non-native English writing.
Can I check purely AI text?
Yes! Simply paste the text generated by ChatGPT, Claude, or Gemini into the box to see how it scores. This is a great way to understand what "AI-sounding" text looks like.
Does this tool store my data?
No. All analysis is performed using local heuristics and temporary processing. We do not store, share, or train models on your text data.
