Browser sidebar assistant for chat, summarising, translating and writing
Monica is an AI assistant that lives mostly in a browser sidebar, with companion apps and a web interface alongside it. Once installed, it can read the page you are on to summarise articles, explain selected text, translate passages, draft replies and answer questions without breaking your flow. Behind the scenes it routes to several leading models, so you can pick one per task rather than committing to a single vendor. The differentiator is placement: instead of a separate chat tab, assistance appears next to whatever document, email or video page you already have open.

It runs as a sidebar attached to your browser, so it can act on the page you are reading. Summarising an article, translating a paragraph or drafting a reply happens in place instead of copying text into a separate tab.
Monica routes requests to several major commercial models and lets you choose one for a given task. The exact list changes as vendors release new versions, and some models are reserved for paid tiers.
For occasional summarising, translation and short chats, yes. Sustained daily use of page reading, long documents and premium models will exhaust the free allowance, at which point a paid plan makes sense.
