Freelance platforms see tons of AI-submitted work now, often from ChatGPT due to its popularity. Good detectors are trained heavily on its outputs, spotting hallmarks like excessive clarity or hedging phrases. In my hiring process, running portfolios through a chatgpt detector weeds out obvious cases early, saving interview time. Follow up with custom prompts for live tests. It's not about banning AI entirely—many use it ethically—but ensuring original voice. This layered approach has improved the quality of writers I onboard significantly.
