Frequently Asked Questions
How accurate is this AI Detector?
It uses statistical analysis of burstiness and perplexity to provide a highly educated probability. It is highly effective at catching raw LLM output, though no detector is 100% foolproof.
Does it save or store the text I paste?
Absolutely not. FreeClientToolbox processes your text entirely within your local web browser. No data is sent to our servers.
What is "Burstiness" in AI detection?
Burstiness refers to the variation in sentence length. Humans naturally write in bursts (short and long sentences), while AI generates uniformly structured sentences.
Can it detect Claude 3 or Google Gemini?
Yes. Most LLMs share underlying mathematical predictability patterns which this tool is designed to detect.
