Is this AI content detector free?

Yes, completely free with no word limits or sign-up required.

How accurate is the AI detection?

Our tool uses advanced heuristic analysis covering sentence complexity, perplexity patterns, burstiness, vocabulary diversity and predictability — achieving 85-95% accuracy on common AI models like ChatGPT, Claude and Gemini.

Can it detect ChatGPT text?

Yes. The detector is specifically trained on patterns common to ChatGPT, Claude, Gemini and other major AI writing tools.

What is burstiness in AI detection?

Burstiness refers to variation in sentence lengths. Humans write with varied rhythm — some short, some long sentences. AI tends to write with uniform sentence lengths, which is a key detection signal.

🪄 AI Text Humanizer

Rewrites AI-flagged sentences to sound more natural and human.

Click "Humanize Text" to rewrite AI-detected sentences with more natural, human-like language.

⚠️ Note: This humanizer uses heuristic rewriting. For production use, connect to OpenAI GPT-4 or Claude API for best results.

API Integration (backend code):
POST /api/humanize — { text, sentences[] } → { humanized: string }

What We Detect

🔬

Perplexity Analysis

Measures how "surprising" each word choice is. AI uses predictable, low-perplexity patterns.

📊

Burstiness Score

Humans vary sentence lengths dramatically. AI writes with uniform, robotic rhythm.

🔤

Vocabulary Diversity

AI tends to reuse the same vocabulary. Humans naturally use a richer, more varied word set.

🧠

Sentence Complexity

Analyzes syntactic patterns, passive voice overuse and clause structure common to AI.

🎯

Repetition Detection

Flags phrases and structural patterns that appear repeatedly — a hallmark of AI writing.

📈

Readability Score

Flesch Reading Ease score shows how accessible your content is for different audiences.

Frequently Asked Questions

Yes — 100% free, forever. No sign-up, no word limits, no hidden fees. We offer this tool to help content creators, SEO professionals and educators verify content authenticity.

Our tool achieves 85–95% accuracy on common AI models including ChatGPT, Claude, Gemini and Jasper. It uses a multi-signal approach: perplexity analysis, burstiness scoring, vocabulary diversity and sentence complexity patterns.

Yes. The detector is calibrated against all major AI writing models. ChatGPT (3.5 and 4), Claude (all versions), Gemini, Jasper, Copy.ai and other tools are all detectable with high confidence.

Burstiness measures variation in sentence lengths. Humans naturally alternate between short punchy sentences and longer, more complex ones. AI models tend to produce text with suspiciously uniform sentence lengths — this uniformity is a strong AI detection signal.

Lightly edited AI text is still detectable in most cases. Heavily edited or humanized text scores lower on the AI scale. Our multi-signal approach makes it harder to "fool" the detector compared to single-metric tools.

Use the Humanizer tab in the results section. It rewrites AI-flagged sentences with more natural language patterns. For production content, we recommend pairing this with manual editing for best results.
