So what is it?

This repository is no longer actively maintained. It was a Chrome browser extension that brought Open WebUI, a web interface for interacting with AI models, directly into your browser as a small popup or sidebar tool. The extension would have let you access AI chat capabilities without leaving whatever webpage you were on. Instead of switching tabs to go to a separate website, you could click an icon in your browser toolbar and get an AI assistant right there. Think of it like having a ChatGPT window floating next to your email or research materials, ready to help you draft messages, answer questions, or brainstorm ideas without losing your place. The project was built with Svelte, a lightweight JavaScript framework that makes browser extensions snappy and responsive. However, the developers have shifted focus away from this approach. If you're interested in running Open WebUI on your computer, the team now recommends using their desktop application instead, which you can find in the separate "open-webui/desktop" repository. That's likely a more stable, feature-complete way to get a local AI interface without dealing with browser extension limitations. This repo serves mainly as a historical reference or starting point for anyone curious about how browser extensions work, but it's not the recommended way to use Open WebUI anymore.
