AI Content Detector
Detect if text was written by AI or a human. Free, instant, no signup required.
Free AI Content Detector — No Signup Required
Our AI Content Detector analyzes any text and determines whether it was likely written by AI (such as ChatGPT, Claude, Gemini, or other large language models) or by a human. Paste your text and get an instant AI detection score with detailed indicators and explanation.
How does the AI detector work?
The detector examines writing patterns commonly found in AI-generated text, including uniform sentence structure, lack of personal voice, generic transitional phrases, overly structured paragraphs, absence of colloquialisms or typos, and hedging language. It produces a score from 0 to 100, where 0 means definitely human and 100 means definitely AI, along with specific indicators found in your text.
Is it really free?
Yes. Basic use is completely free with no signup required. Just paste your text and click detect. No email address, no credit card, no account needed.
How accurate is AI detection?
No AI detector is 100% accurate. Our tool provides a probabilistic score based on common patterns in AI writing. Heavily edited AI text or human text that follows very structured formats may produce mixed results. Use the score as a guideline rather than a definitive answer.
Who needs an AI content detector?
Educators checking student submissions, editors verifying content originality, content managers reviewing freelance work, SEO professionals ensuring authentic content, and anyone who wants to verify whether text was written by a human or generated by AI.
