What is Open WebUI?

Open WebUI is a beautiful, feature-rich web interface that gives you a ChatGPT-like experience with your local AI models. It runs entirely in your browser, connecting to the Ollama backend on your Mac, providing a familiar chat interface without any cloud dependency.

Unlike ChatGPT or Claude subscriptions that cost $20+/month and send your data to external servers, Open WebUI keeps everything local. It supports multiple users with separate accounts and conversation histories, making it perfect for families, small teams, or businesses that want shared AI access without shared data.

The interface supports real-time model switching — start a conversation with a fast model for quick questions, then switch to a larger model for complex reasoning, all in the same chat window. It also includes file upload, image generation previews, and markdown rendering for beautifully formatted responses.

MacAI configures Open WebUI to auto-start as a local web service, accessible from any device on your network. Your phone, tablet, or any computer in your home or office can access your private AI through a simple browser bookmark.
