MacAI is a native macOS AI chat application that connects to virtually any AI provider from one fast Swift interface, with 934 stars on GitHub.
MacAI (macOS AI) is a simple yet powerful native chat client for the Mac. Instead of keeping a browser tab open for every service, you chat with ChatGPT, Claude, Grok, Gemini, Perplexity, OpenRouter, Ollama and more from a single SwiftUI app that feels at home on macOS. Privacy is a design priority: there is no telemetry, data flows directly from your Mac to the AI service you choose (or stays local with Ollama), and API tokens are stored securely in the Apple Keychain. Beyond plain chat, MacAI supports image generation and editing, customisable AI assistants with their own instructions, iCloud sync across your devices and fast local search across thousands of conversations.
MacAI is free — the website lists its price as 0 USD — and open source under the Apache-2.0 license. You bring your own API keys or local models, so any costs are whatever your chosen AI providers charge.
MacAI is for Mac users who talk to several AI services and want one polished, private desktop app instead of many browser tabs. It is a particularly good fit for people who mix cloud models with local Ollama models and care about keeping their keys and conversations on their own machines.
