How AI Detection Works

An AI detector built for research 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 research papers be checked for AI?▼

Yes. The detector understands academic research conventions — citations, methodology structure, and formal register — and analyzes writing patterns accordingly.

Does it flag cited material?▼

No. The engine focuses on original writing while accounting for quoted and referenced content in context.

Is my unpublished research safe to submit?▼

Research data is processed transiently. Nothing is retained, copied, or accessible after the analysis finishes.

Should I check the whole paper or by section?▼

Section-by-section checking gives more granular dimension reports, especially useful for papers with distinct parts like methods, results, and discussion.
