macai

macai is a native macOS chat client that connects to a wide range of large‑language‑model APIs, including OpenAI’s ChatGPT, Anthropic’s Claude, xAI’s Grok, Google Gemini, Perplexity, Ollama, OpenRouter and any OpenAI‑compatible service. Users supply an API token for the chosen provider, after which the app offers a minimalist light or dark interface for conversational interaction. It also supports additional capabilities such as vision, image generation, web‑search integration, reasoning tools, and import/export of chat histories.

The application is built specifically for macOS 14.0 and later, running on both Intel and Apple‑silicon hardware. It can be installed via a notarized universal binary or through Homebrew as a cask. iCloud sync keeps chats, messages, and settings consistent across a user’s devices, while the app itself does not implement telemetry, though Apple may collect anonymized data when iCloud sync is enabled.

macai targets developers, researchers, and anyone who wants a lightweight, system‑integrated way to experiment with multiple LLM providers without leaving the desktop environment. Its design emphasizes simplicity, local execution of open‑source models via Ollama, and extensibility through a settings panel that lets users add custom API services.
