Metric37 rewrites AI-generated text and scores the output for naturalness. If the score is too low, you iterate. You can see word-level diffs between versions, compare rewrites side by side, and keep going until the writing actually sounds like yours.
Built for freelancers, content teams, and agencies who use AI to draft but need the output to sound like a human wrote it.
