Monica AI
Monica AI
Multi-model AI assistant for the browser, desktop and mobile
Overview
Monica is an all-in-one AI assistant that works in the browser, on desktop and on mobile. It brings several AI models together for chat, writing, translation and summarising, and adds image and video generation, PDF analysis, and an AI agent. The vendor describes it as an assistant that sits alongside any web page.
The free plan gives about 40 basic-model queries per day with limited trials of image and video generation, ChatPDF and the agent. Paid prices vary by source and billing period. Zemith, which checked on 19 October 2026, lists Pro at $9.90 to $16.60 per month, Unlimited at $16.60 to $24.90 and Ultra at $82. Krater instead lists yearly plans: Pro $99, Max $199 on sale and Ultra $995 per year. Advanced model use is metered by credits, so heavy users may hit limits.
Because the assistant can read the pages you browse and the files you upload, avoid sharing confidential material and review the privacy policy. Check the output of any AI assistant before relying on it. This page is a summary based on public listings and the vendor’s own description, dated 2026-11-13. It was not tested hands-on, and details may have changed.
