AI Detector by 5Tools

Originality.ai

Best overall

For most everyday users, Originality.ai wins because it offers a polished, credit-based system with industry-leading AI detection accuracy and a Chrome extension that tracks writing history—ideal for content creators who need reliable, scalable checks. AI Detector by 5Tools is faster and free for basic scans, but its lack of mobile support, API, and clear pricing makes it better suited for quick, one-off checks rather than regular use.
