FAQ

Frequently Asked Questions

Have a question? Contact me on Twitter or by email.

  • 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 6 MB in size — lightweight and privacy-focused.

  • Yes! RewriteBar works with almost any application or website that supports text input.

    Here are some examples:

    • Google Chrome
    • Google Docs
    • Microsoft Word
    • Slack
    • WhatsApp
    • Emails
    • Microsoft Teams
    • Notion
    • Visual Studio Code
  • Yes! You can try RewriteBar for free with up to 100 corrections. After that, you can upgrade to a subscription or one-time license.
  • Yes, you can request a refund within 7 days of purchase. Just reach out via email.
  • RewriteBar has been tested with English and German, but it should work with any language supported by ChatGPT. If you encounter issues with a specific language, feel free to contact us.
  • After your purchase, you'll receive an email with:

    • A download link for the app
    • A license key to activate it
    • The license key also includes unlimited app updates.

    The license key also includes unlimited app updates.

  • There are no additional costs with the subscription plan. If you're using the one-time license, you’ll need to provide an OpenAI API key, which may incur charges based on your usage. For most users, around $1 per month is enough to get started.
  • You can cancel your subscription through the Subscription Portal.
    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).
  • The app requires macOS accessibility permissions to retrieve the selected text and replace it with the corrected version. This enables RewriteBar to work with any application. No data is stored.
  • You can create an account on OpenAI and generate a new API key.
    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. The subscription plan includes access to the RewriteBar AI Cloud and is ideal for users who don’t want to manage their own API key.
  • No, there is no Windows version. RewriteBar is built with native macOS tools and isn’t compatible with Windows. If you're on Windows, you can try this alternative:Grammarsen.
  • You can reach out any time by email. I’m happy to help!
