Kaku

Kaku is a lightweight, open-source macOS application that lives in your menu bar and provides instant access to a variety of large language models (LLMs). It allows users to switch between different AI providers and models seamlessly, making it easy to compare responses or use the best model for a given task. Built with simplicity and speed in mind, Kaku is designed for developers and power users who want frictionless AI access without switching between browser tabs or apps.

• Multi-model support: Connect to and chat with multiple LLMs including OpenAI, Claude, Gemini, and more from a single unified interface.
• Menu bar access: Lives in the macOS menu bar for instant, always-available access without opening a full application window.
• Quick switching: Easily switch between different AI models and providers mid-conversation to compare outputs or leverage model strengths.
• Open-source: Fully open-source on GitHub, allowing community contributions, transparency, and self-hosting of configuration.
• Minimal UI: Clean, distraction-free chat interface focused on speed and usability rather than feature bloat.
• Keyboard-friendly: Designed for keyboard-driven workflows, letting you invoke and interact with AI without leaving your current task.

To get started, download the latest release from the GitHub repository, install it on your Mac, and configure your API keys for the LLM providers you want to use. Once set up, click the menu bar icon to open the chat panel and start interacting with your chosen model instantly.
