How AI Detection Works

An AI detector built for thesis 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.

Frequently Asked Questions

Can theses be checked for AI?▼

Yes. Paste individual chapters for granular analysis — each gets its own dimension report.

Is it free throughout the entire research process?▼

Yes. There are generous daily usage limits that stay consistent across the semester.

Can the detector handle academic formatting?▼

Yes. The engine accounts for citations, footnotes, and academic structure — focusing analysis on your original writing rather than referenced content.

Does the detector confuse scholarly writing with AI text?▼

It distinguishes between genuine academic writing and AI-generated academic patterns. Polished scholarly prose that shows varied sentence structure and original argumentation rarely triggers false positives.

Is dissertation content kept confidential?▼

Processing occurs entirely in transient memory. Nothing is retained, stored, or viewable after the check completes.
