Security reflects where data goes, requested permissions and incidents on record at the verification date. It is not a guarantee of zero risk: check the deployment mode and the connections you enable.

What it does, concretely

Switching between tools to summarize a page, translate text or generate an image wastes time. Monica centralizes these tasks in a browser extension accessible from any web page.

In practice, a keyboard shortcut (Cmd+M or Ctrl+M) opens a side panel where you can chat with multiple AI models (GPT, Claude, Gemini, among others), summarize the current page, translate content, draft or rewrite text, and generate images. A contextual toolbar also appears when you select text on a page.

Monica is aimed at professionals who process large amounts of online information: entrepreneurs, analysts, researchers, developers, marketing teams, and customer service staff. It offers ready-to-use templates for specific use cases such as contract analysis, SQL query generation, or SEO content writing.

On the other hand, users who only need a single AI model or who work mainly outside the browser will find the tool oversized. Free users are subject to a daily usage limit, which can hinder intensive use.

What it offers

·Multi-model chat: access GPT, Claude, Gemini and other models from a single side panel.

·Immersive full-page translation with bilingual display.
·Contextual toolbar to explain, rephrase or translate any selected text.
·Writing assistant to draft or improve content directly in text fields on web pages.

·Custom bot creation platform with workflow automation (paid).
·PDF analysis, document translation and key point extraction (paid).

Our tips

Use the Cmd+M (Mac) or Ctrl+M (Windows) shortcut to open Monica without leaving the page you are viewing.
Select text on any page to bring up the contextual toolbar and quickly access explanation, translation or rephrasing features.
Browse the ready-to-use templates (over 80 available) for recurring tasks such as marketing copy generation or document analysis, rather than starting from a blank prompt.
Enable AI answers displayed directly on search engine results pages to compare sources and summaries at a glance.
Monica is also available as a desktop app (Windows, macOS) and mobile app (Android, iOS), so you can access your conversations across all your devices.

Watch out

The extension reads all pages you visit, which represents broad access to your browsing data: worth considering if you consult sensitive or confidential pages.
Free users face a daily usage limit, which can interrupt work mid-day if the limit is reached.
