How AI Detection Works

An AI detector built for essays goes beyond basic keyword matching. When you paste text, the DeepSense™ engine scans multiple linguistic dimensions simultaneously. Each dimension generates an independent score, and those scores combine into the AI probability shown in your report. Text with natural variety scores low; accumulated AI patterns drive the score up.

Each dimension generates an independent score, and those scores combine into the AI probability shown in your report. Text with natural variety scores low; accumulated AI patterns drive the score up. You get actionable insight, not just a verdict — the dimension breakdown shows you exactly which specific patterns were detected.
