 Free checkers are convenient but often rely on older models, leading to outdated detection or strict limits. Paid versions usually offer higher accuracy, unlimited scans, and detailed reports. For light personal use, free might suffice, but if you're checking regularly—like for work—an ai checker with premium features saves time and reduces errors. I've noticed paid ones handle nuanced language better, catching subtle AI traces while ignoring idiomatic expressions. Test trials if available. Ultimately, it depends on your volume and how critical accuracy is to you.
