How AI Detection Works

An AI detector built for everyone 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 any text be checked for AI?

Yes. Paste any English text — email, social media post, article, message — and get an AI probability score instantly.

What kinds of text work best?

The detector is most reliable with 30+ words. Longer passages give the multi-dimension engine more patterns to analyze across sentence structure, vocabulary, and transitions.

Will casual writing or text messages get falsely flagged?

Casual human writing tends to be irregular — varied sentence length, natural repetition, uneven rhythm. AI output is often too smooth and uniform, which is what the detector catches.

Is anything saved from my check?

No text is kept. The entire analysis happens in temporary memory and is purged on completion.
