Code-signing certificates cost hundreds of dollars per year — we haven't purchased one yet. The app is safe: no spyware, no data harvesting, no background processes beyond the hotkey listener.
- Run the installer — Windows will warn you.
- Click "More info" in the SmartScreen dialog.

02 / Privacy
Your privacy, simply explained.
No vague promises — here's exactly what the app does with your text.
Rewritr reads only the text you've highlighted when you press the shortcut. It never monitors your clipboard passively or watches what you type.
Your text is sent to the AI to generate a rewrite, then discarded. We do not store, sell, or analyze your content.
The only background process is a single global hotkey — a standard Windows API call. The same mechanism used by Snipping Tool and Spotify.
03 / FAQ
Common questions. Straight answers.
Yes. The "Unknown Publisher" warning appears because we haven't purchased a code-signing certificate yet — not because the app is dangerous. The installer contains no malware, adware, or spyware. You can inspect the network traffic yourself: it only communicates with our API when you manually trigger a rewrite.
No. It registers a single global hotkey (Ctrl + 1) using the standard Windows API — the same mechanism used by apps like Snipping Tool or Spotify. It does not record, monitor, or transmit any keystrokes or typing activity.
Your text is sent to the AI model, a rewrite is returned to your clipboard, and that's it. We don't store the content of your rewrites on our servers.
