AI Content Detector — Human or Machine?
Paste any text and find out whether it was written by a human or generated by AI. Our detector analyzes linguistic patterns, sentence structure, and stylistic signatures.
How AI Detection Works
Our AI analyzes linguistic patterns that distinguish human writing from machine generation, looking at multiple dimensions simultaneously.
Pattern Analysis
AI-generated text tends to be overly polished, balanced, and formulaic — with predictable transitions like "In conclusion," "Moreover," and hedging phrases like "It is worth noting that..."
Human Markers
Human writing has more sentence-length variety, personal anecdotes, emotional nuance, and unpredictable phrasing. We look for these organic signatures.
Verdict & Reasoning
Get a 5-level verdict — from AI-Generated to Human-Written — with detailed reasoning and specific suspicious patterns flagged for your review.
What We Look For
Key linguistic signals that help distinguish AI-generated content from human writing.
Uniform Sentence Length
AI tends to produce sentences of similar length and complexity, lacking the natural rhythm of human writing.
Overuse of Transition Words
Excessive use of "furthermore," "additionally," "consequently" — AI relies heavily on explicit connectors.
Lack of Personal Voice
Rare use of "I think," "in my experience," or other first-person perspective markers.
Balanced Argumentation
AI text often presents both sides too evenly — "on one hand... on the other hand" — without taking a stance.
Imperfections & Quirks
Minor typos, colloquialisms, contractions, and informal phrasing strongly suggest human authorship.
Specific Examples & Anecdotes
References to real-world specifics, personal stories, and concrete examples are hallmarks of human writing.

Frequently Asked Questions
Common questions about AI content detection accuracy and limitations.
How accurate is AI detection?
Current AI detectors achieve 70-90% accuracy depending on text length and the AI model used. Longer texts (500+ words) yield more reliable results. No detector is 100% accurate — always use results as one factor in your assessment.
Can it detect all AI models?
Our detector is trained to recognize patterns from GPT-3.5, GPT-4, GPT-4o, Claude, Gemini, and other major LLMs. Newer or fine-tuned models may be harder to detect.
What text length works best?
For reliable results, we recommend at least 200-300 words. Very short texts (under 50 words) do not contain enough linguistic signal for accurate analysis.
Will human-edited AI text be detected?
Heavily edited AI-generated text can be harder to detect. Our analysis identifies underlying patterns that even light editing may not fully mask, but heavily rewritten content may read as human.
