What is the AI Content Detector?

The AI Content Detector is a free, browser-based tool that analyzes text to estimate whether it was written by AI or a human author. Using advanced heuristic analysis of writing patterns — including sentence variation, vocabulary diversity, repetitive phrases, and paragraph structure — it provides a probability score and confidence level to help you make informed decisions about content authenticity.

How to Detect AI Content in 3 Easy Steps

  1. Paste Your Text: Copy and paste the content you want to analyze (articles, essays, emails, or any written text).
  2. Scan for AI Patterns: Click "Scan Text" to analyze writing patterns using multiple heuristic signals.
  3. Review Results: Check the AI probability score, verdict, and confidence level to assess authenticity.

Key Features & Detection Signals

  • Multi-Signal Analysis: Analyzes sentence variation, vocabulary diversity, n-gram repetition, AI phrase frequency, and paragraph uniformity.
  • Real Heuristic Detection: Uses genuine pattern analysis, not random simulation — results change meaningfully based on actual input.
  • 100% Client-Side Privacy: All analysis happens locally in your browser. Your text is never uploaded or stored on any server.
  • Free, Unlimited Use: No subscriptions, no signup, and no limits on how many texts you can analyze.

Frequently Asked Questions (FAQ)

Is the AI Content Detector free to use?

Yes, it's completely free with no signup required and no limits on usage.

How accurate is AI content detection?

This tool uses heuristic pattern analysis and is most accurate on longer texts (150+ words). It provides an estimate, not a definitive verdict — use it as a first-pass indicator alongside human judgment.

Is my text data kept private?

Yes, all analysis happens locally in your browser. Your text is never uploaded to or stored on any server.

What makes text look AI-generated?

Common AI signals include uniform sentence lengths, repetitive phrases, overuse of transition words like "moreover" and "furthermore," low vocabulary diversity, and very consistent paragraph structures.

Guide

AI Content Detector Guide: Verify Authenticity with Confidence

In today's content landscape, distinguishing AI-generated text from human writing is increasingly important for educators, publishers, and content creators. The AI Content Detector analyzes multiple writing pattern signals — sentence variation, vocabulary diversity, repetitive phrases, and structural uniformity — to provide an evidence-based estimate of AI authorship. While no detector is perfect, this tool offers a reliable first-pass check that can flag suspicious patterns for further review. Use it to verify student submissions, evaluate freelance content, or ensure your own writing maintains a natural, human voice. Remember: this is a helpful indicator, not a final verdict — always combine automated analysis with human judgment and context.
