Free AI Content Detector

Detect AI-generated text with advanced detection technology. Analyze up to 50,000 characters instantly.

Thousands of texts analyzed
0 / 50,000 characters

Paste any text to check if it was written by AI or a human. Works best with at least 250 words.

Note: Content generated with Rankability or any other AI tool will often be detected as AI generated. That is expected and it does not automatically hurt your SEO performance. Google is not against AI content. It is against low quality, unoriginal content that does not provide new value or information gain. Use AI to speed up drafting, then have a human review, edit, and enhance every piece before publishing.

Frequently Asked Questions

How accurate is the AI detector?

Our proprietary detection system delivers superior accuracy by cross-validating results from multiple independent detection engines. Each scan is analyzed simultaneously through our multi-source process, with scores blended to eliminate single-source bias and reduce false positives.

What is perplexity and burstiness?

Perplexity measures how predictable text is - AI writing tends to have low perplexity. Burstiness measures variation in sentence structure - humans write with more variation. Together, these metrics help identify AI-generated content.

Can I use this tool for plagiarism detection?

This tool specifically detects AI-generated content, not plagiarism. If you're looking to detect copied content from other sources, you'll need a dedicated plagiarism checker.

Is my content stored or shared?

No. The text you analyze is processed for detection but is not stored or shared. We do not retain analyzed documents.
