Monica

What is Monica?

Monica is an AI assistant that brings several large language models together in one place, so you can chat, write, translate, summarize and research without keeping separate accounts. It works as a browser extension with a sidebar and toolbar, a web app, desktop apps for Windows and Mac, and mobile apps for Android and iOS. Beyond chat it offers ChatPDF with a full-text reading mode, image generation with models such as SDXL, and agent features including Deep Research, Create Slides and Browser Operator, plus a code assistant for VS Code and JetBrains. Usage is metered through query counts and advanced credits. The Free plan gives 40 basic queries a day, while the Pro, Max and Ultra subscriptions add monthly advanced queries and credits that reset on the first of each month. Subscribers who run out can buy more credits, from 4,000 credits for US$ 10 up to 40,000 for US$ 100.
