Monica AI

Monica is an AI assistant delivered mainly as a Chrome and Edge browser extension, with companion apps for Windows, Mac, iOS, and Android. It sits in the browser sidebar and gives users access to multiple frontier language models in one place, letting them switch between options rather than being locked to a single provider. Core capabilities include chat, summarizing web pages and YouTube videos, drafting and editing writing, translating pages for bilingual reading, real-time AI search with web access, text-to-image generation, and a code assistant that plugs into VS Code and JetBrains IDEs. It integrates with everyday tools like Google Search, YouTube, Gmail, and GitHub so it can act on the page a user is already viewing. Monica also offers a developer platform for API access, extending the assistant beyond the browser into custom applications. It is built by Butterfly Effect Pte. Ltd. and follows a freemium model, with a free tier offering a limited number of daily queries and paid Pro and Pro+ tiers unlocking higher usage and more models. The tool is aimed at knowledge workers, researchers, and content creators who want a single AI layer across their everyday browsing rather than juggling separate chatbot tabs.
