AI Content Detector — Writing Review

Writing Signal Review examines pasted or selected text for explainable patterns associated with formulaic writing. It is a cautious review aid, not an authorship detector and not proof that text was written by AI or by a person. Features: • Local deterministic analysis with no remote API or model • Clear risk-indicator bands and sentence-level explanations • Sample-quality guidance; samples under 40 words are not scored • Confidence capped at medium to avoid false certainty • Up to 25 recent reviews stored only in the browser • Copy and download reports that always include the not-proof limitation Paste text into the popup, or select text on a page and invoke the context-menu action. No selected text, pasted text, or result is sent over the network. The extension has no host permissions. Writing patterns overlap across human and machine-assisted text. Do not use this tool as the sole basis for academic, employment, moderation, legal, or disciplinary decisions.
