How to Check for AI Text

1

Paste Your Text

Copy any text you want to analyze — essays, assignments, research papers, articles, blog posts, emails, reports, cover letters, or creative writing. Our detector accepts English text of any length. No formatting required, just paste and go.

2

Run the Analysis

Click "Check for AI" and our DeepSense™ engine scans across multiple linguistic checkpoints — sentence structure, vocabulary patterns, transition density, template phrases, nominalization, academic register, and more.

3

Get Your AI Score

Within seconds you'll see a percentage score — the likelihood your text contains AI-generated patterns. Each dimension shows a pass/fail indicator so you know exactly which patterns were detected.

What Makes Our AI Detector Different

Our DeepSense™ engine analyzes multiple linguistic checkpoints to give you a clear picture of whether text was written by a human or generated by AI models like ChatGPT, GPT-4, Claude, and Gemini.

How AI Detection Works

With AI writing tools like ChatGPT, GPT-4, Gemini, and Claude now generating everything from essays to business reports, an AI detector has gone from nice-to-have to essential. Our free AI checker doesn't just slap a percentage on your text and call it done — it runs a comprehensive DeepSense™ analysis that shows you exactly which writing patterns look machine-generated and why. Instead of a single black-box score, you get a detailed breakdown across multiple linguistic markers.

When you paste text into the checker, the engine runs a simultaneous scan across multiple checkpoints. Each produces an independent score, and those scores combine into the overall AI probability you see in the report. This granular approach means you don't just get a number — you see exactly why the engine reached its conclusion, with each checkpoint scored and explained transparently.

That's why we built the humanizer directly into the same tool. If the detection report shows high AI probability, you can rewrite the flagged sections immediately and recheck until the score drops. It's the most efficient workflow for anyone who needs to detect AI content and fix it in one place.

Frequently Asked Questions

How does the DeepSense™ AI detector work?

DeepSense™ runs multiple independent linguistic analyses simultaneously — each dimension independently scored and weighted. Instead of a single black-box percentage, you get a transparent breakdown showing exactly which patterns were detected and why.

Which AI models can it detect?

ChatGPT, GPT-4, Claude, Gemini, and all major AI models. Our engine detects the underlying writing patterns common across all AI text, regardless of which model generated it.

Can AI detectors make mistakes?

No detection tool provides absolute certainty on every text. That's why the dimension breakdown is valuable — it shows you exactly which patterns were flagged, giving you context to make your own assessment rather than relying on a single number.

Is the AI detector really free?

Yes — free to use. The humanizer also has a daily word allowance. Get started right away.

What's the difference between the detector and the humanizer?

The detector tells you if your text looks AI-generated — with a score and a full dimension breakdown. The humanizer fixes it — rewriting AI-sounding sections into natural human prose. Use both in one workflow: check, humanize what's flagged, then recheck.
