Frequently Asked Questions
How does the AI Content Detector work?
The detector analyzes 8 linguistic signals including sentence uniformity, transition word density, passive voice, vocabulary diversity, hedging language, list patterns, repetitive phrases, and colloquial markers. AI-generated text tends to be highly uniform and formal while human writing is more varied and personal.
Is this AI detector free?
Yes, 100% free with no signup, no account, and no limits. Everything runs locally in your browser. We never store, transmit, or read your text.
Can it detect text from ChatGPT, Claude, and Gemini?
Yes. All major AI models share similar linguistic patterns: uniform sentence lengths, overuse of transitions like "Moreover" and "Furthermore," excessive hedging, and lack of personal voice. The detector identifies these shared fingerprints.
How accurate is AI content detection?
No detection tool is 100% accurate. Our analyzer provides a probabilistic assessment based on 8 signals. Heavily edited AI text, or human writing in formal/academic contexts, may produce less definitive results. Use it as a guide, not a verdict.
How can I make AI-generated text sound more human?
Vary your sentence lengths dramatically, remove formal transitions, use contractions, add personal anecdotes and opinions, break up lists into prose, and cut filler phrases like "It is important to note." Our Prompt Mega Pack includes prompts specifically designed to produce natural-sounding output.
Is my text AI generated if I used AI to help write it?
AI-assisted writing exists on a spectrum. If you used AI for a first draft but heavily edited it with your own voice and ideas, it may score lower (more human). The detector measures the linguistic fingerprint of the final text, not how it was produced.
