Monica

Monica is an AI copilot that consolidates access to today's leading foundation models — GPT-4/5-class chat, Claude, Gemini, and specialized image and video models — behind a single interface that follows the user across a Chrome/Edge extension, dedicated desktop apps, and iOS/Android. Instead of juggling separate ChatGPT, Claude, Perplexity, and image-generator tabs, operators highlight text on any webpage to summarize, translate, rewrite, explain, or answer, then switch model providers from a dropdown without leaving the page. The product goes beyond a lightweight extension: it ships a full chat workspace with prompt library, memory, and file/PDF understanding; a writing surface that mirrors Notion-style editing with inline AI actions; and utilities for image generation, background removal, and short-form AI video creation. For search-heavy workflows, Monica includes a Perplexity-style AI search that cites sources, plus deep-research and 'reasoning' modes routed to whichever underlying model is best suited. The freemium model gives most users enough headroom for daily browsing and writing tasks, while Pro tiers unlock higher rate limits on premium models, longer context, and heavier image/video generation. The clear positioning: a horizontal, multi-model AI layer for knowledge workers who don't want to be locked into one vendor's app.
