Frequently asked questions
Is my writing uploaded or sent to AI?
No. Segmentation, formulas, rule-based hints, comparison and exports run locally without an account or remote model.
Why is there no Chinese school grade score?
English grade formulas do not transfer reliably to Chinese. The Chinese view reports descriptive sentence, paragraph, punctuation and repetition measures instead of inventing a grade.
Does a high clarity score mean the content is correct?
No. Readability measures surface complexity patterns; they do not verify facts, grammar, accessibility compliance or the author's intent.
Are passive voice and filler suggestions always wrong?
No. They are deterministic review candidates. Technical, legal and rhetorical contexts can justify them, so the tool keeps every edit under user control.
