Disclaimer
Important limitations of AI detection technology and how results from this tool should — and should not — be used.
Critical notice for educators and institutions: AI detection scores are probabilistic estimates, not proof of authorship. Using a detection score as sole evidence in academic disciplinary proceedings, grade penalties, or employment decisions is inappropriate and potentially harmful. This tool is designed as a first-pass screening signal only.
A high AI probability score does not confirm that text was AI-generated. A low score does not confirm that text was human-written.
What This Tool Does and Does Not Do
What it does
Returns a statistical probability score indicating how closely submitted text matches patterns associated with AI-generated content. Provides sentence-level analysis showing which parts of the text are most statistically similar to AI output.
What it does not do
It does not determine with certainty whether text was written by a human or an AI. It cannot identify which specific AI tool was used. It cannot account for editing, paraphrasing, or mixed authorship. It is not a substitute for human judgment.
What results should never be used for
As sole or primary evidence in academic misconduct proceedings. As the basis for grade penalties or course failures. As proof in legal, employment, or contractual disputes. As a definitive determination of plagiarism or academic dishonesty.
Known Accuracy Limitations
All AI detectors, including the tool on this site, have documented failure modes. The following table summarizes known limitations based on independent 2026 benchmarks:
| Limitation | Detail | Implication |
|---|---|---|
| False positive rate | 12–17% on human-written text | 1 in 6–8 human texts may be incorrectly flagged |
| ESL writer bias | 61.3% of TOEFL essays flagged (Stanford, 2023) | Non-native English writers face disproportionate false flags |
| Edited AI text | Accuracy drops to 76–78% after human revision | Revised AI content is significantly harder to detect |
| Humanized AI text | Detection drops to ~65% after humanizer tools | Processed AI content often passes detection |
| Short texts | Unreliable on texts under 50 words | Short passages produce low-confidence scores |
| Polished writing | Higher false positive rate on grammatically consistent text | Strong writers may score higher than expected |
Guidance for Educators
If you are using AI detection tools in an academic context, the consistent guidance from researchers and educational bodies is:
Use detection scores as a prompt for conversation, not as evidence for punishment. A student who wrote their own work can typically explain their arguments, describe their revision process, and answer questions about their sources. The conversation is the verification — the detection score is the reason to have it.
Academic integrity policies that rely solely on automated AI detection scores risk penalizing students who wrote their own work, disproportionately impacting ESL students, and creating adversarial environments that undermine the educational relationship. We strongly recommend treating any detection result as one data point among many.
