What the analysis found
Important: This score measures selected writing patterns; it is not a probability of AI authorship. These heuristics have not been validated against an authorship dataset. Transition checks use English phrases. Formal writing, templates and other languages can affect the result. Use it for review, not as evidence of authorship or misconduct.
Additional writing quality checks
Review clarity, tone and meaning. These English-language suggestions do not change the AI-like score and cannot establish authorship. The 30-word threshold is an editing aid.
The SWS AI Content Detector looks at measurable characteristics of the text, including sentence-length variation, repeated phrases, vocabulary diversity and highly uniform writing. These signals are combined into an estimated AI-like writing score.
The analysis is intentionally described as an estimate. Human writing can look predictable, while AI-generated writing can be heavily edited to look natural. A score should never be treated as definitive proof.
Useful for a first-pass content review
Writers, editors, students, teachers and website owners can use the tool to spot overly repetitive or uniform writing. For publishers, it can also help identify passages that may benefit from clearer examples, personal context or more varied sentence construction.
FAQ
AI detector questions
Can an AI detector be 100% accurate?
No. Detection is probabilistic and false positives and false negatives are possible. Treat results as indicators rather than proof.
What score means the text was written by AI?
There is no universal threshold that proves AI authorship. This tool reports how strongly the text matches selected AI-like writing patterns.
Is my pasted content uploaded?
No. The basic detector logic runs in your browser and does not submit the analyzed text to the SWS server.
