MindMac is a native macOS AI chat client for people who want local models and cloud providers in one app. Its inline mode lets you get writing help inside Notes, Mail and browsers without switching to a separate chat window.

Local and cloud connections: Use Ollama, LM Studio, LocalAI, GPT4All, llama.cpp or MLX servers, alongside providers such as OpenAI, Azure OpenAI, Gemini and Claude. Custom endpoints must be compatible with OpenAI's Chat Completions API.
Inline writing: Generate text or ask questions within other applications, with customizable keyboard shortcuts.
Conversation organization: Search chat history, arrange conversations in nested folders and reuse prompt templates. You can choose how much earlier conversation text the model receives.
Documents and web search: Upload documents, search through services including Brave Search and Kagi, and export conversations to PDF or Markdown.
Voice and images: The app supports voice input, text-to-speech and DALL·E image generation.

MindMac runs on Intel and Apple Silicon Macs with macOS 13 or newer. It stores app data locally and API keys in Apple Keychain. The selected backend determines where model processing happens: cloud connections send prompts off your Mac, and MindMac doesn't relay prompts through its own servers.

The app offers free and paid access and doesn't require a MindMac account. Using OpenAI requires an OpenAI account and API key; its API access is separate from ChatGPT Plus.
