Why we built this
We were using AI to draft client work. The drafts were fast but sounded like every other AI output on the internet. Clients noticed. Detectors flagged it. We tried paraphrasers, synonym swappers, prompt tricks. Nothing worked well enough.
So we built Metric37. Rewriting with a scoring loop, so you can actually see your text improve. It is the tool we wanted to exist.
1,500 words free. No credit card. Paste something and see.
