Why this exists

We started Metric37 in 2025 because we were using AI to draft client work and the output kept getting flagged. Not by detectors, by clients. The writing was correct but lifeless. We tried every paraphraser and humanizer we could find. They all did the same thing: swap synonyms, shuffle words, hope for the best. The text still read like AI wrote it.

So we built something different. Metric37 rewrites your text, scores the result for naturalness, and retries if the score is too low. You can edit, re-score, compare versions, and keep going until the writing actually sounds like yours. It is the tool we wanted when we were handing in client work and hoping nobody would notice.

How we think about it

Iteration over magic

Good writing takes more than one pass. We give you a scoring loop so you can see what is working and what still needs fixing.

Your content stays yours

We encrypt everything, never train on your data, and you can delete anything at any time. Your words are not our product.

Made for people who ship words

Freelancers, agencies, content teams. If your reputation depends on what you publish, this is built for you.
