ScribeLens AI Detector

Check selected text for AI-writing signals on ScribeLens, with sentence-level evidence. Results are probabilistic, not proof.

Check any text for AI writing. Most AI detectors hand you a single percentage. ScribeLens shows which sentences read as AI-like, which read as human, and the reason behind each flag, so the decision stays with you. Select text on any page and right-click "Check with ScribeLens". A side panel shows the result next to the page: the overall result, the share of human, mixed and AI-like sentences, and the sentences most worth a look, with the reason for each. Open the full report on scribelensai.com in one click. Or click the toolbar button and paste text. • Sentence-by-sentence highlighting: human-like, mixed, AI-like • A plain-language reason for every flag • Reference lists and citations excluded automatically on academic text • Free checks of up to 2,000 words with no signup; longer text opens on scribelensai.com, where free accounts get 35,000 words a month and 9 PDF/DOCX report exports • English text only
