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.

Frequently Asked Questions

Can papers be checked for AI?

Yes. Paste the paper and get an AI probability score with a dimension-by-dimension breakdown.

What types of papers can be checked?

Term papers, research papers, position papers, analytical essays — any academic writing in English.

How does the detector handle academic writing style?

The engine recognizes academic writing conventions — thesis structures, citations, and formal tone — analyzing patterns within that context. Varied sentence structure and original argumentation are not mistaken for AI patterns.

Is my paper stored after checking?

No copies persist. Processing is done entirely in volatile memory with nothing written to disk.
