What This Tool Checks
Two independent checks run in parallel on your document — all in your browser, nothing stored.
AI Writing Indicators
Analyses your text for statistical patterns associated with AI-generated writing — sentence length uniformity, vocabulary burstiness, predictable phrasing, and transition word density. Designed to flag content that may be picked up by university AI detection tools.
Plagiarism & Similarity
Cross-references your key phrases against Wikipedia — the most commonly copied academic source — using Wikipedia's public API. Also generates Google exact-phrase search links so you can verify any passage against the full web in a single click.
Expert Academic Support
If your scan raises concerns, our team of PhD-qualified UK academic writers can help. From targeted rewriting to full dissertation support — checked for originality, properly referenced, and delivered to your deadline.
Understanding Your Results
Two separate scores — here's how to read each one and what to do next.
Low likelihood. Your writing shows strong indicators of human authorship. Sentence variety and vocabulary are both high.
Some patterns detected. A few AI-like writing patterns were found. Review flagged passages and add more individual analysis and sentence variety.
Significant indicators. Multiple AI-like patterns identified. Rewrite flagged sections in your own voice before submission.
High likelihood. Substantial AI writing patterns throughout. This may be flagged by university detection tools. Significant revision is recommended.
ℹ️ No AI detector is perfectly accurate. Formal academic writing can sometimes score higher due to structured phrasing. Use this as a guide, not a verdict.
Excellent. No significant phrase matches found. Your work appears highly original — use the Verify Online links for a final spot-check.
Acceptable. Some matches detected — typical for well-cited academic work. Check that all flagged phrases are properly attributed.
Review required. Multiple matches found. Rephrase or properly cite each flagged passage before submitting.
High risk. Significant matching phrases detected. Substantial rewriting and proper citation are required before this work can be submitted.
ℹ️ Reference lists and standard academic terminology will naturally produce some matches — these are not plagiarism if properly cited.
