How to use
Paste or type your text into the box above, then click Check Text. RheyKit analyzes several writing characteristics and provides an AI-like writing-pattern score.
What does the score mean?
A lower score means fewer of the structured writing patterns measured by this tool were detected. A higher score means more of these patterns were detected.
The score should not be treated as proof that a person or AI wrote the text. Human writing can naturally produce structured patterns, and AI-generated text can also be edited.
What does this tool check?
The checker examines sentence-length variation, vocabulary diversity, repeated meaningful words, long sentences, formal transition phrases and other measurable characteristics of the text.
Important information
AI detection is not an exact science. Results are provided for general analysis and should not be used as definitive proof of AI authorship or human authorship.
Core processing happens directly in your browser. Your text is not intentionally uploaded to a RheyKit backend by this tool.
Frequently Asked Questions
Is this AI checker free?
Yes. The RheyKit AI Writing Checker is designed for free browser-based use.
Does this tool upload my text?
No. The checker performs its core analysis directly in your browser and does not intentionally upload your text to a RheyKit backend.
Can this tool prove that text was written by AI?
No. The result represents AI-like writing patterns detected in the text. It should not be considered definitive proof of authorship.
What does a high AI-like score mean?
It means the text contains more of the structured writing patterns measured by the checker. It does not mean that AI authorship has been confirmed.
Can human-written text receive a high score?
Yes. Human writers can naturally produce formal, repetitive or highly structured writing, so the score should always be interpreted carefully.
