- 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.

If you have any questions, feel free to contact us via email. - No, a ChatGPT Plus subscription is not required. The OpenAI API operates on a pay-as-you-go basis, so you only pay for what you use. Alternatively, you can use the RewriteBar AI Cloud (included in the subscription plan).

Setup instructions are available in our help center - The one-time license requires an Provider API key (OpenAI or other) and may incur usage-based costs from the Provider.
