KWT AI Detector helps you check whether selected or pasted text looks AI-written — without leaving the page. HOW TO USE 1. Select text on any webpage (or paste text in the side panel). 2. Click the KWT AI Detector icon — a side panel opens on the right. 3. See AI vs human likelihood scores and color-highlighted sentences. 4. Drag the panel edge to resize. FEATURES • One-click analysis from page selection or manual paste • Sentence-level highlighting (AI-leaning spans marked clearly) • Same detection engine as https://www.kwtspider.com/ai-detector/ • Free: 30 successful detections per day (UTC), server-enforced • Optional KWT-AID license for higher plan limits (same keys as the website) IMPORTANT Detection scores are probabilistic estimates, not proof of authorship. Short or heavily edited text can be less reliable. Privacy: Text is sent to KWT Spider servers only when you run an analysis. Privacy policy: https://www.kwtspider.com/privacy-policy.php
