AI Text Detector & Humanizer

Paste any text to analyze it for common AI-generated writing patterns. The tool examines six key signals: sentence length uniformity, vocabulary diversity, burstiness (rhythm variation), AI-typical phrases, transition word density, and paragraph structure. Get actionable tips to make your writing sound more natural.

What This Tool Checks

Sentence Uniformity — AI tends to write sentences of similar length. Human writing varies dramatically. Vocabulary Diversity — measured by Type-Token Ratio. AI often reuses the same words more. AI Phrases — detects overused phrases like "delve into," "it's important to note," "in today's world." Transition Density — AI overuses connectors like "however," "furthermore," "moreover." Burstiness — human writing has rhythm — short punchy sentences mixed with long flowing ones. AI is smoother. Paragraph Structure — AI paragraphs tend to be similar in length.

Frequently Asked Questions

Is this a replacement for GPTZero or Originality.ai?+
No. This tool uses statistical heuristics, not ML-based perplexity models. It's useful for understanding patterns in your writing, but should not be used as the sole basis for accusations of AI use. Professional detectors like GPTZero use fundamentally different approaches.
Can human text be flagged as AI?+
Yes. Formal, academic, or technical writing can score high because these styles share some patterns with AI text (uniform sentence length, formal transitions). This is a known limitation of all AI detection methods.
