Everything you need to know about Zimmer before you download.
Zimmer is a local AI assistant for Mac that runs entirely on your computer. Unlike ChatGPT, Claude, or Gemini, Zimmer never sends your data to the cloud. It downloads powerful AI models directly to your machine so you can write, research, plan, and automate work privately, with no internet required after setup.
No. While Zimmer includes tools for writing and running code, it's built for anyone who wants a capable AI assistant. You can use it for writing, research, content creation, project planning, design work, and more, entirely through conversation or voice, with no technical knowledge required.
Most people are up and running in under 5 minutes. Zimmer automatically downloads its AI engine on first launch, and the built-in Model Hub recommends and installs the right AI model for your specific Mac. No API keys, no configuration, no technical setup required.
Zimmer is optimized for Apple Silicon Macs, including M1, M2, M3, and M4. It uses your Mac's GPU for fast local AI processing. The Model Hub automatically filters models based on your available RAM, chip, and storage so you only see options that will actually perform well on your machine.
No. Everything Zimmer does, including reading files, generating responses, and running agents, happens locally on your Mac. Your prompts, files, and conversations never leave your device, are never stored on external servers, and are never used to train any model.
Only for the initial setup and model downloads. Once your AI models are installed, Zimmer works 100% offline, including voice input, voice responses, file access, and all agent tasks. No internet required to use it day to day.
Zimmer is currently in preview and free to try. During preview, there are no token limits or rate limits while your work runs locally on your own Mac.
None during preview. Because Zimmer runs on your own Mac rather than shared servers, your day-to-day usage is bounded by your local hardware, not a cloud quota.
Three key differences: privacy, local control, and capability. Zimmer runs entirely on your Mac and your data never leaves your device. There are no preview token limits or rate limits. And Zimmer's agents can actually access your files, run commands, and take real actions on your computer. ChatGPT, Claude, and Gemini process everything on their servers and can only work with what you paste into a chat window.
Yes. Zimmer has a voice agent for spoken conversations and task execution, plus system-wide dictation that lets you speak instead of type in any app on your Mac, even when Zimmer is minimized.
Yes. Zimmer integrates with Slack, GitHub, GitLab, Notion, Google Calendar, Gmail, Google Drive, Asana, and more. Agents can read and send messages, create issues, update documents, and interact with these tools directly while completing a task, without you switching between apps.
Yes. Zimmer supports multiple AI agents working in parallel. For example, one agent can build a feature while another reviews it simultaneously. You can assign different AI models to different agents, give each one a specific role, and run them side by side. Most cloud AI tools are single-conversation only and cannot do this.
