Preguntas frecuentes
How accurate are best AI checkers?
AI content detectors are generally good but not perfect. They can identify patterns common in AI-generated text, but no detection tool offers 100% accuracy. False positives (human text flagged as AI) can happen, so always use them as a guide, not a final verdict.
Can AI writing be undetectable?
It’s becoming harder to achieve truly undetectable AI-generated writing. As AI models get smarter, so do AI content detection tools. However, editing and “humanizing” AI output can make it much less likely to be flagged by a detector.
Why should I use an AI checker?
Using an AI checker helps you ensure your content is original and authentic. This is vital for academic integrity, SEO rankings, and building trust with your audience. It helps you avoid accidental AI influence and verify content quality.
Do AI checkers detect all AI models?
Most good AI detection tools are trained on various AI models, including popular ones like ChatGPT, Gemini, and Claude. Reputable detectors, like Winston AI or GPTZero, constantly update to catch new AI patterns, but it’s an ongoing race.
What is the best free AI checker?
Several free AI detector options exist, such as Quillbot’s free AI Detector or GPTZero’s limited free plan. While useful for basic checks, free versions often have limitations. For more reliable and accurate AI detection, a paid tool is usually more effective.
