Theo

Private AI for Mac, now with vision

Introducing Theo, a private, on-device AI app for Mac that lets you run compatible local models directly on your own machine. Theo is designed for people who want to explore AI without sending prompts, conversations, or images to the cloud. Write, chat, code, and work with vision models in a native Mac experience built around privacy and control.

Theo makes local AI approachable with a clean interface for choosing models, adjusting how they respond, and staying in control of your workflow. Built for efficient on-device performance on Apple silicon, Theo helps you move quickly while keeping your data on your Mac.

Whether you are using Theo for writing, coding, or image understanding, everything happens locally. That means you can explore modern AI capabilities in a more private, dependable way, without relying on external services for every interaction.

Built for vision

Theo supports vision models so you can work with images alongside text right on your Mac. Review screenshots, inspect visual content, and explore multimodal workflows in a private environment where your inputs stay under your control.

Download models from Hugging Face

Theo makes it easy to browse and download compatible models from Hugging Face directly in the app. Choose a model, download it to your Mac, and start using it locally within minutes. Your models stay on your device, and your prompts and conversations remain private.

Requires an Apple silicon Mac running macOS Sonoma 14.5 or newer.
