FAQ from RewriteBar

How Does It Work? +

RewriteBar captures your selected text via the macOS clipboard and sends it to a language model for processing. The corrected version is then automatically pasted back, replacing the original text.

Is RewriteBar Safe? +

Yes. RewriteBar does not store or track your data. Processing depends on your chosen provider: With the default RewriteBar service, your text is sent to a server to be processed by a language model and returned; your text and API keys are not stored. With third-party providers like OpenAI, Mistral, or Ollama, your request is sent directly from your device to their API, meaning RewriteBar does not see or process your text. The app is a lightweight, 6 MB native macOS tool focused on privacy.

Can RewriteBar Be Used in Any App and Webpage? +

Yes, RewriteBar functions with almost any application or website that supports text input, including Google Chrome, Google Docs, Microsoft Word, Slack, WhatsApp, email clients, Microsoft Teams, Notion, and Visual Studio Code.

Is There a Free Trial? +

Yes, you can try RewriteBar for free with up to 100 corrections. Afterward, you may choose to upgrade to a subscription or a one-time license.

Can I Get a Refund? +

Yes, you can request a refund within 7 days of your purchase by contacting us via email.

Which Languages Are Supported? +

RewriteBar has been tested with English and German, but it should support any language compatible with ChatGPT. Please contact us if you experience issues with a specific language.

What Happens After I Purchase? +

Upon purchase, you will receive an email containing a download link for the app and a license key for activation. This license key also provides access to unlimited app updates.

Are There Any Additional Costs? +

There are no additional costs with the subscription plan. If you use the one-time license, you must provide your own OpenAI API key, which may incur usage-based charges. Most users find that approximately $1 per month is sufficient to get started.

How Do I Cancel My Subscription? +

You can cancel your subscription through the Subscription Portal. If you have questions, please contact us via email.

Do I Need a ChatGPT Plus Subscription for RewriteBar? +

No, a ChatGPT Plus subscription is not required. The OpenAI API uses a pay-as-you-go model, or you can use the RewriteBar AI Cloud included with your subscription plan.

Why Does the App Need Accessibility Permissions? +

The app requires macOS accessibility permissions to retrieve your selected text and replace it with the corrected version, allowing it to work across any application. No data is stored.

How Do I Get an API Key? +

You can create an account on OpenAI to generate an API key. Setup instructions are available in our help center.

What Is the Difference Between the Subscription and the One-Time License? +

The one-time license requires you to provide your own provider API key (such as OpenAI) and may incur usage-based costs. The subscription plan includes access to the RewriteBar AI Cloud, which is ideal for users who prefer not to manage their own API keys.

Is There a Windows Version? +

No, there is no Windows version. RewriteBar is built with native macOS tools and is not compatible with Windows. If you are on Windows, you may consider the alternative: Grammarsen.
