What is an AI Detector for copywriters?
GPTinf AI Detector for Copywriters is a text analysis tool that scans ad copy, emails, landing pages, and other client-facing writing for AI-generated patterns. It takes a piece of text as input and returns a probability score showing how much of it reads as AI-written. Copywriters use it to check drafts before delivery, so their output meets human-writing standards expected by clients and platforms.
