Frequently Asked Questions

1. How does RewriteBar work? RewriteBar uses the native macOS accessibility and clipboard functions. When you trigger it with a keyboard shortcut, it captures your selected text, sends it to your chosen AI provider (either our cloud service or your own API), and then automatically pastes the improved text back in its place.

2. Is my data safe and private? Yes. Your privacy is a priority. How your data is handled depends on your setup:

• RewriteBar Subscription: Your text is sent to our server, which securely forwards it to a language model. We do not store your text or API key.

• Your Own API Key (One-Time Purchase): Your request is sent directly from your Mac to the AI provider (e.g., OpenAI, Anthropic). RewriteBar's servers never see or process your text.

• Local AI (Ollama): All processing happens entirely on your own machine, ensuring complete privacy.

3. What is the difference between the subscription and the one-time license? The Subscription Plan is an all-in-one solution that includes access to our AI Cloud service, so you don't need to manage your own API key. The One-Time License is for users who prefer to use their own API key from providers like OpenAI. With this option, you pay a single price for the app and then pay the AI provider directly for your usage (pay-as-you-go).
