- Template Adherence: How tightly the phrasing follows widespread, inflexible templates usually utilized by fashions like GPT-5.
In apply, SynthQuery interprets these advanced statistical indicators into an general label (Human, AI, or Combined), accompanied by per-sentence scores you can examine manually.

The system estimates patterns related to typical machine prose on widespread net and educational distributions; it doesn’t infer intent or catch a particular product by title.
What’s DeepScan mode? DeepScan (a function highlighted in SynthQuery) is a heavier, extra advanced evaluation path. It’s tuned for combined human-and-AI writing, frivolously edited mannequin textual content, or stylistically uncommon passages the place sooner fashions may disagree. It consumes extra compute energy however supplies a way more rigorous examine.
