- 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.
Here are some examples:
- Google Chrome
- Google Docs
- Microsoft Word
- Slack
- 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!
