Tellbuster points out the phrases that make writing read like AI, explains why each one stands out, and suggests a plainer way to say it. Readers now notice phrases like "Let's delve into", "In today's fast-paced world" or "It's not just X, it's Y". Tellbuster finds them before you hit send, so you can decide what to keep. Tellbuster is a linter, not a detector. It never says your text "is AI". People use these phrases too. It shows you what readers notice.
