Introduction
What is Momo: AI Assist?
Momo: AI Assist is a Chrome browser extension that provides an elegant AI chat sidebar experience. You can open the sidebar anytime while browsing any webpage to chat with AI, without switching tabs or opening other apps.
Momo's core philosophy is "friendly and practical" — it's not just a chat interface, but a comprehensive AI assistant integrating web search, page capture, image understanding, and deep reasoning.
