AI text detector
Check the pattern.
Keep your judgment.
Estimate whether an English essay or other student writing shares patterns with AI-generated writing. The result is a clue for review, not proof of authorship.
How to Read an AI Detector Result
An AI detector estimates how closely a document matches patterns found in AI-generated writing. RewritePal returns a percentage and one of three bands. The number is a probability, not a verdict.
- Likely human: the document shares more patterns with human writing in the evaluation data.
- Uncertain: there is no clear pattern either way. Read the writing itself and avoid strong conclusions.
- Likely AI: the document shares more patterns with AI-generated writing. It still does not prove how the text was written.

Frequently Asked Questions
- How does the RewritePal AI detector work?
- It compares document-level signals in your text with examples of human and AI-generated student writing, then returns a probability and a band: likely human, uncertain, or likely AI.
- Can an AI detector prove who wrote a text?
- No. No detector can know who wrote a text or how it was produced. Treat the result as a clue for review, and never use it alone for academic, hiring, or disciplinary decisions.
- What text works best?
- English essays and other student writing between 50 words and 10,000 characters. Short text, other languages, and very different genres give weaker signals.
- Is the AI detector free?
- Yes. Each check uses one of your free daily AI actions. A free account gets more daily actions than a guest.
- Does RewritePal log the text I check?
- No. Your writing stays out of application logs.
