Private AI Assistant for Mac: Secure, Private, and Trusted
For developers, lawyers, and enterprise professionals, "convenience" is often a trap. Most AI writing tools are essentially keyloggers that send every word you type—passwords, trade secrets, personal emails—to a server in the cloud.
If you are searching for a private AI assistant for Mac, you know that "trust us" isn't a privacy policy.
The Risk: Browser Extensions are Keyloggers
Read the permissions on your grammar checker extension: "Read and change all your data on the websites you visit."
That includes your Google Docs, your bank login page, and your internal company dashboard. When you use a cloud-based AI, you are training their next model with your intellectual property.
The Rephrase Promise: Your Data Stays Yours
Rephrase is designed for the paranoid (and the smart).
- Native App Sandboxing: We are a sandboxed macOS app, adhering to Apple's strict security guidelines. We cannot see what you type unless you explicitly select it and activate the tool.
- Zero Training: We use industrial AI models via API, but we explicitly use a "Zero Training" policy. Your text is for your eyes only.
- No Stored History: We don't store your text history on our servers.
The Private AI Checklist
| Feature | Typical Cloud AIs | Rephrase |
|---|---|---|
Reads All Inputs | Yes (Extension) | No (On-Demand) |
Data Training | Yes (Default) | No |
Processing | Cloud Training | API-Zero (No Training) |
Apple Notarized | Varies | Yes |
Conclusion
Security is not an optional feature. If your work involves sensitive data, you cannot afford to use a browser extension.
Switch to a native, private AI assistant that respects the boundaries of your digital life.
