Open WebUI
Open WebUI is a desktop AI chat app that lets you run models locally or connect to Open WebUI servers from one interface.
What is Open WebUI?
Open WebUI is a desktop AI interface for chatting with language models on macOS and other desktop platforms. It helps individuals, developers, and teams use local or remote AI models without relying on a browser-based setup every time. The desktop app can run Open WebUI directly on your machine, and it can also connect to existing Open WebUI servers so you can switch between different environments from one place. Notable user-facing capabilities include a floating chat bar, screenshot capture for sending on-screen content into chats, voice input, and optional local model inference through a built-in engine. It is designed for people who want a more app-like workflow for AI conversations, prompt work, and model access across local and self-hosted setups. Open WebUI Inc. also provides broader documentation and ecosystem tools around the Open WebUI platform.

Safety overview
Status: Mostly safe
This is legitimate AI software for local and remote model access. Some features may request access such as microphone or screen capture when you use voice input or screenshot tools, and that access is normal for those functions. The desktop app is described by its publisher as an early alpha, so you may encounter bugs or behavior changes during updates. If you use local models, the app may store chats, model data, and settings on your Mac and can use significant disk space and memory.
Recommendation: Keep Open WebUI if you use it for local AI chats, self-hosted model access, or connecting to Open WebUI servers. If you no longer use it, removing the app is reasonable, but you may also want to remove its stored data later if you want to free additional space or clear conversation history.
