AI scanner typically refers to AI-powered content detectors or AI checkers that scan text to determine if it was generated or assisted by artificial intelligence tools like ChatGPT, GPT-5, Claude, Gemini, or similar large language models. These tools analyze patterns such as predictability, burstiness, sentence structure, perplexity, and stylistic markers to provide a probability score indicating how likely the content is AI-produced versus human-written.
Is AI Scanner Free or Paid?
AI scanners are predominantly freemium. Most leading tools offer meaningful free access for basic scans—paste text, get an instant AI probability score and highlights—without requiring payment or heavy limits, making them suitable for occasional or moderate use.
AI Scanner Pricing
Pricing for AI scanners varies by tool but often follows a credit/word-based or subscription model. Free tiers provide generous limits, with paid plans starting affordably for unlimited or pro features.
