What it is

Screenshot of the CheckerAI homepage
checkerai.io, as visitors see it

CheckerAI is a free web-based AI detection tool that helps users identify signs of AI-generated writing. Users can paste text or upload documents in PDF, Word, TXT, or Markdown formats up to 20 MB and receive an overall score plus highlighted passages that resemble AI writing.

The tool is designed for multiple use cases including checking essay drafts before submission, reviewing student work, analyzing articles before publication, and examining team content. Long documents are automatically processed in sections with one combined score at the end.

CheckerAI provides an informational estimate through pattern analysis rather than confirmation of which specific words were generated. The service requires no account creation and keeps no detection history, though it uses external processing services for text analysis.

What it is built with

  • Score-based detection showing how closely text resembles AI writing
  • Highlighted passages showing flagged sections in context
  • Support for multiple file formats including PDF and Word documents
  • No account or registration required
  • Automatic sectioning for long documents
  • Detection of multiple AI writing models
  • No submission history or database storage

Questions from the bench

Is this AI checker free?
Yes, text checks and document imports are free with no account or subscription needed.
Can this AI checker detect ChatGPT writing?
You can check text from ChatGPT, Claude, Gemini, and other writing tools, though results vary between tools and versions and edited output can be missed. The detector cannot reliably identify which specific model was used.
How accurate is an AI detector?
No AI detector gets every text right and CheckerAI has not published an independent accuracy benchmark. The tool can flag human writing or miss generated text, and a score alone is not sufficient evidence for grading, hiring, or publication decisions.
What does an AI detector score mean?
The score estimates how closely text resembles AI writing without confirming which specific words were generated. For long documents, section scores are combined, with longer sections influencing the total more.
Is my text stored or shared?
CheckerAI does not publish submissions or keep a detection history in its database. The service uses external processing providers and temporary storage for PDF and Word imports, with details on data handling in the Privacy Policy.
