Accuracy and limitations
How Accurate Are AI Detectors?
Understand AI detector accuracy, false positives, false negatives and why scores should be handled as guidance.

Limitations guide
Explain uncertainty, false positives, false negatives and the need for human review.
Accuracy depends on context
AI detector accuracy varies by text length, topic, editing history, language, model type and writing style. A result may be more useful for a long, coherent sample than for a short message or heavily edited paragraph.
False positives can happen
Human writing can be flagged when it is formal, polished, translated, templated or edited with writing tools. This is why detector results should never be used as automatic proof.
False negatives can happen too
AI-generated text can be edited, paraphrased or mixed with human writing. A low score does not prove that no AI assistance was used.
A safer interpretation
Treat the result as a probability-style signal. Review the writing, consider the use case, compare supporting evidence and document decisions where the outcome matters.
FAQ
Are AI detectors 100% accurate?
No. No detector can guarantee perfect accuracy or prove authorship with certainty.
Why do human texts get flagged?
Formal tone, templates, editing tools and translation can make human writing look more predictable.
What is the safest way to use a detector?
Use it as one review signal alongside human judgement, policy, context and supporting evidence.
Guidance, not proof
AI detection results are guidance only. No detector can prove authorship with certainty, and important decisions should include human review and appropriate context.
