About Monica
All-in-one AI extension with a sidebar for chat, page summaries, translation and writing help on any site.
Monica is a browser extension that adds an AI sidebar to Chrome and Edge, with apps for other platforms as well. You open it on any page to chat, summarize the page or a YouTube video, translate text, or rewrite something you have selected.
It gives access to models from several AI companies under one account, with a limited free tier and paid plans for heavier use. Because it works across every site you visit, it asks for broad permissions when you install it.
Things to check: the permissions it requests at install, whether you want it active on sites where you handle client or company data, and how the plan you choose counts usage across different models. A quick test is to open it on a long article and compare its summary with the article's own conclusion.
