Free AI Content Detector

Detect AI-generated text with a free, instant analyzer. Get an AI probability score, classification, and the specific patterns — overused words, transition phrases, sentence uniformity — that flag ChatGPT, Claude, and Gemini output.

Built for ai content detector

Check AI-written text before you publish

Use this AI content detector to scan blog posts, landing pages, essays, or outreach copy for the repetitive patterns that make machine-written text feel generic.

Because the analysis runs in your browser, you can review drafts privately, rewrite the most obvious signals, and publish cleaner content without sending sensitive copy to a third-party checker.

Common use cases

  • QA AI-assisted drafts before client delivery
  • Reduce obvious ChatGPT phrasing before publishing SEO content
  • Compare rewrites until the text reads closer to likely human
Minimum 50 characters, 20 words. Detection improves with longer samples (300+ words ideal).
