What is Monica?
Monica is an AI assistant that puts models from several providers behind one interface for chat, search, writing, translation, summarising and image creation. It is available as a web app, a browser extension for Chrome and Edge, desktop apps for Windows and Mac, and mobile apps for Android and iOS. In the browser, a sidebar opens on any page with a keyboard shortcut, a toolbar explains or translates selected text, and AI answers can appear next to search results. Monica also summarises web pages and YouTube videos, drafts email replies, translates pages into a bilingual view and answers questions about PDFs. Users can build and share custom bots, and a separate Monica Code assistant works in VS Code and JetBrains IDEs. The service is operated by Butterfly Effect Pte.
