Limitations & False Positives
AI detection is a helpful signal, but results can vary depending on text type, length, and writing style.
When human writing may look “AI-like”
- Short samples: small excerpts don’t provide enough signal for stable analysis.
- Formal academic tone: structured phrasing and consistent style can resemble AI outputs.
- ESL / multilingual writing: natural language patterns may be misread as “uniform.”
- Heavy editing or rewriting: over-smoothing can reduce natural variation.
- Paraphrased text: rewriting tools can introduce patterns that trigger flags.
- Quotes & citations: templated academic structures may affect results.
- Template-based tasks: similar formats across submissions can look repetitive.
What to do if text gets flagged
- Scan more text: include several paragraphs from the middle of the essay.
- Check multiple sections: don’t judge based on only one excerpt.
- Look for specificity: add concrete details, original reasoning, and clear sources.
- Re-check after revisions: confirm that the final draft reflects the author’s voice.

What an AI Score Means
Treat the result as a probability signal—not proof. Use it to guide review, not to make final judgments.
How to read the outcome
- Low AI likelihood: writing shows varied structure and natural human patterns.
- Medium AI likelihood: some sections may be highly uniform or heavily edited—review key parts.
- High AI likelihood: multiple signals match common AI-style patterns—review carefully and verify context.
What affects the result most
- Length: longer samples usually produce more stable signals.
- Genre: academic summaries and reports naturally look more “structured.”
- Editing: rewriting and “polishing” can increase uniformity.
- Mixed authorship: combining AI + human text can create uneven signals across sections.
