Frequently Asked Questions
Your Questions, Answered
- RewriteBar captures the currently selected text using the macOS clipboard and sends it to a language model for rewriting. The corrected version is then automatically pasted back, replacing the original text.
Yes. RewriteBar does not store or track any of your data. How your text is processed depends on the provider you choose:
- RewriteBar (default): Your selected text is sent to the RewriteBar server, which forwards the request to a language model and returns the corrected version. We do not store your text or API key on our server.
- Third-Party Providers (e.g. OpenAI, Mistral, Ollama): Your request is sent directly from your device to the provider’s API. RewriteBar never sees or processes your text.
The app is built using native macOS tools and is just ~20 MB in size — lightweight and privacy-focused.
Yes, RewriteBar works with almost any application or website that supports text input. It runs quietly in the background so you can stay focused and keep your writing flow.

If you encounter issues with a specific language, feel free to contact us.
- RewriteBar (once purchased) and local models do not incur additional costs. Additional charges apply only when using cloud AI providers via the BYOK (bring your own API key) option. In that case, you pay your chosen provider directly.
- You can cancel your subscription through the Subscription Portal.
If you have any questions, feel free to contact us via email. - No. Subscriptions like ChatGPT Plus/Pro or Claude Pro apply to their chat applications. API access is billed separately by each provider on a pay-as-you-go basis and is not included in those subscriptions. You can use your own API key (BYOK) and pay the provider directly, or use the RewriteBar AI Cloud (included in the RewriteBar subscription).
- RewriteBar requests macOS Accessibility permissions so it can function as designed. This allows the app to read your currently selected text and replace it with the improved result, so it works seamlessly in your favorite apps. We do not store your data.
- You can create an API key with any supported provider below:Setup instructions are available in our help center
One-Time License: Includes all RewriteBar features but requires you to set up your own API accounts with AI providers (OpenAI, Anthropic, etc.). You pay the providers directly for usage.
Subscription: Includes all features from the one-time license plus RewriteBar Cloud access and priority support. No need to set up API accounts—you can access the same AI models through our cloud service. You can still use your own API key (BYOK) or local models at any time.
- No. There is no Windows version, and none is planned. RewriteBar is purpose‑built and optimized for macOS. We may explore a Chrome extension in the future.
