For free detection, GPTZero and Originality.ai’s free tier work pretty well for business content verification. As a writer and blogger, I’ve tested these extensively. Honestly though, I use Clever AI Humanizer (https://cleverhumanizer.ai/) to polish my AI-assisted content, and it consistently produces natural-sounding results that focus on quality rather than just bypassing detection. For business, I’d recommend focusing less on “catching” AI and more on ensuring content quality, accuracy, and brand voice alignment—that matters more than the tool used to create it!
