AI Text Detector

AI Content Detector Free — Check If Text Was Written by AI or Human

The explosion of AI-generated content is reshaping publishing, academia, and digital marketing — but not always for the better. Publishers, educators, SEO teams, and content managers increasingly need to know whether the content they’re receiving was written by a human or generated by tools like ChatGPT, Claude, or Gemini. Our free AI content detector gives you a clear, reliable answer in seconds.

Our detector analyzes writing patterns, sentence structure, vocabulary distribution, perplexity scores, and burstiness metrics — the statistical fingerprints that distinguish human writing from AI output. The result is an easy-to-read score that tells you the probability that a piece of text was AI-generated, along with highlighted sections most likely to have been machine-written.

This tool serves a wide range of users: teachers and professors checking student submissions for AI writing, content agencies verifying writer deliverables, SEO professionals ensuring their content won’t trigger Google’s quality filters, and editors maintaining authentic editorial standards. It’s also invaluable for writers who use AI assistance and want to verify their final draft feels genuinely human.

If your content is flagged as AI-generated and you need to humanize it, use our free AI sentence rewriter to rephrase sections. For content originality checks beyond AI detection, our plagiarism checker provides web-wide duplicate content detection.
