Your text

All scoring, proof marks, readability indices, tone signals and counts are calculated by JavaScript in your browser. That text is not sent to us.

When you press a button marked AI (rewrite, tone read, grammar check, jargon translation, subject line ideas), the text in the box is sent to our server and on to an AI model through Vercel AI Gateway to generate the answer. We do not store that text or the answer, and we do not use it to train anything. Error logs may briefly record that a request failed, not its content.

Saved in your browser

So you don’t lose work on a refresh, your current draft and your last subject line are saved in your browser’s local storage on this device. They never leave your device unless you press an AI button. You can delete them at any time:

Analytics

We use Ahrefs Web Analytics to count page views. It is cookieless and does not collect personal data or the text you type.
