You can check your draft for AI tells before you publish.
Scan your draft for the stock phrases and patterns that make writing sound machine-made. Click a match to jump to it, and decide what to change.
Readers notice the patterns.
"Let's dive in." "It's not just X, it's Y." "In today's fast-paced world." Once readers spot phrases like these, they stop trusting the rest.
They are easy to miss in your own draft, especially after a few rounds of AI edits. The scan finds them for you.
