Contact me on [Twitter](https://x.com/m91michel) or by [email](mailto:support@rewritebar.com?subject=Question%20about%20RewriteBar). - ### How Does It Work? 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. - ### Is RewriteBar Safe? 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 25 MB in size — lightweight and privacy-focused. - ### Can RewriteBar Be Used in Any App and Webpage? 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. Examples include: - Google Chrome - Google Docs - Microsoft Word - Slack - WhatsApp - Emails - Microsoft Teams - Notion - Visual Studio Code - ### Is There a Free Trial? Yes, you can try RewriteBar for free with 35,000 credits. No credit card required. When you’re ready to continue, choose a one-time Standard or Pro license. - ### Can I Get a Refund? Yes, you can request a refund within 14 days of purchase. Just reach out via [email](mailto:support@rewritebar.com?subject=Rewritebar%3A%20Refund%20request). - ### Which Languages Are Supported? RewriteBar App Interface is translated into 12 languages. The translation action supports over 500 languages. However, language Support also depends on the selected model. State of the Art cloud models support most languages, while smaller local models can only support a limited number of languages. If you encounter issues with a specific language, feel free to contact us. - ### Do Any Additional Costs Apply? 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. - ### How Do I Cancel My Subscription? You can cancel your subscription through the [Subscription Portal](https://billing.stripe.com/p/login/bIYdUVc87ad72Wc4gg). If you have any questions, feel free to [contact us via email](mailto:support@rewritebar.com?subject=Rewritebar%3A%20Cancel%20subscription). - ### Do I Need a ChatGPT Plus Subscription for RewriteBar? 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). - ### Why Does the App Need Accessibility Permissions? 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. - ### How Do I Get an API Key? You can create an API key with any supported provider below: - [OpenAI](https://platform.openai.com/) - [Anthropic](https://platform.claude.com/) - [Google](https://aistudio.google.com/) - [Groq](https://console.groq.com/) - [DeepSeek](https://platform.deepseek.com/) - [OpenRouter](https://openrouter.ai/) - [Mistral](https://mistral.ai/) - [XAI](https://x.ai/api) - [TogetherAI](https://www.together.ai/) - [Azure AI Foundry](https://azure.microsoft.com/products/ai-foundry) - [LM Studio](https://lmstudio.ai/) - [302.AI](https://help.302.ai/en/docs/ji-cheng-dao-OpenAI-guan-fang-SDK) - [Amazon Bedrock](https://docs.aws.amazon.com/bedrock/latest/userguide/bedrock-mantle.html) - [Baseten](https://docs.baseten.co/development/model-apis/overview) - [Cloudflare AI Gateway](https://developers.cloudflare.com/ai-gateway/usage/chat-completion/) - [Cortex](https://cortex.so/docs/capabilities/embeddings/) - [DeepInfra](https://deepinfra.com/docs/openai%5Fapi) - [Firmware](https://voltagent.dev/models-docs/providers/firmware/) - [Fireworks AI](https://docs.fireworks.ai/tools-sdks/openai-compatibility) - [Hugging Face](https://huggingface.co/docs/inference-providers/tasks/chat-completion) - [io.net](https://io.net/docs/reference/ai-models/get-started-with-io-intelligence-api) - [Moonshot AI](https://platform.moonshot.ai/console/api-keys) - [MiniMax](https://platform.minimax.io/docs/api-reference/text-openai-api) - [Nebius Token Factory](https://docs.tokenfactory.nebius.com/api-reference/introduction) - [OpenCode Zen](https://opencode.ai/docs/zen) - [OVHcloud AI Endpoints](https://www.ovhcloud.com/en/public-cloud/ai-endpoints/catalog/) - [Scaleway](https://www.scaleway.com/en/docs/managed-inference/reference-content/openai-compatibility/) - [Venice AI](https://docs.venice.ai/) - [Vercel AI Gateway](https://vercel.com/docs/ai-gateway/sdks-and-apis/openai-compat) - [Z.AI](https://docs.z.ai/guides/develop/openai/python) - [ZenMux](https://docs.zenmux.ai/guide/quickstart) - [Cerebras](https://cloud.cerebras.ai/) Setup instructions are available in our [documentation](https://rewritebar.com/docs) - ### What Is the Difference Between the Subscription and the One-Time License? **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 Gateway 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. - ### Is There a Windows Version? 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. - ### I Have Another Question You can reach out any time by [email](mailto:support@rewritebar.com?subject=Question%20about%20Rewritebar).
