Monica AI

Monica AI is a popular AI assistant browser extension that, like Sider, adds AI capabilities to the browser without requiring switching to a separate application. With millions of users, Monica has built strong adoption as an accessible entry point to AI assistance for users who want AI without the friction of standalone subscriptions.

The extension provides a keyboard shortcut (typically Alt+M on Windows, Cmd+M on Mac) to open the AI chat alongside any webpage, making it easy to ask questions about what is being read or get assistance with writing tasks in any web text field.

Webpage summarisation distils any article into a brief overview, and the AI can answer follow-up questions about the summarised content. For news readers, researchers, and students who read many articles, this summary-first approach allows quickly assessing article relevance before investing full reading time.

Chatbot access, writing assistance, grammar checking, and image generation are included in the extension alongside the contextual webpage features. The breadth of included capabilities makes Monica a generalist AI tool rather than a specialist one.

Monday also has a standalone mobile app and desktop experience beyond the browser extension, providing consistent AI access across devices.

At $8.99/month for Pro, Monica is priced comparably to Sider and provides similar core functionality. The choice between them often comes down to interface preference and which specific features are used most. Both serve the same use case of reducing AI switching friction during browser-based work.
