Onit SideKick is an open-source macOS AI chat sidebar that docks to any application, letting users chat with LLMs using highlighted text or the current window as context. It supports multiple remote providers (OpenAI, Anthropic, Google, etc.) and local models via Ollama with a privacy-focused Local Mode.

Use cases

• chat with AI about text I highlighted in any app
• use my current window as AI context without copy-pasting
• dock an AI chat sidebar next to any Mac application
• use local LLMs via Ollama for private AI chats
• switch between Claude, GPT, and Gemini in one assistant
• ask AI about error messages on my screen

When to choose

• you want a Cursor-Chat-like AI assistant across all macOS apps, not just your IDE
• you want to mix cloud and local (Ollama) models in one desktop chat tool
• privacy matters and you want local-only inference or direct provider API calls

When to avoid

• you need a Windows or Linux assistant - it is macOS only
• you need voice dictation (Onit Dictate is a separate, closed-source product)
• you want a fully open-source stack end to end - parts of the ecosystem are proprietary
