MacCopilot vs RewriteBar

Choosing the right AI-powered macOS assistant can be a game-changer. This comparison breaks down MacCopilot and RewriteBar to help you decide which tool best fits your workflow.

Summary

MacCopilot is a native macOS copilot AI that lets you select any area of your screen and chat about it using OpenAI (including GPT-5.5), Claude, Google Gemini, Ollama, or a compatible endpoint. It focuses on visual analysis and screen-based interactions, with flexible screenshot capture. MacCopilot is a $19.99 one-time license with your own API keys and no bundled model quota. RewriteBar is a specialized text editing assistant that lives in your menu bar, offering a command-palette UI for instant grammar/spelling fixes, tone shifts, summarization/expansion, and translation into 500+ languages. RewriteBar starts at $29 for a one-time license. An optional RewriteBar Gateway add-on ($5/month or $40/year) adds hosted models if you do not want to use your own API key.

Frequently Asked Questions

Your Questions, Answered

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 ~20 MB in size — lightweight and privacy-focused.

  • 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
  • Yes, you can try RewriteBar for free with up to 100 corrections. When you’re ready to continue, you can choose a subscription or a one-time license, whichever suits you best.
  • Yes, you can request a refund within 14 days of purchase. Just reach out via email.

  • 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.

  • 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.
  • You can cancel your subscription through the Subscription Portal.
    If you have any questions, feel free to contact us via email.
  • 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).
  • 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.
  • You can create an API key with any supported provider below:Setup instructions are available in our documentation

  • 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.

  • 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.
  • You can reach out any time by email. I’m happy to help!
