About "Monica"
What is Monica
Monica is an all-in-one AI assistant that lets you switch among multiple cutting-edge AI models on a single subscription. Provided by Butterfly Effect (the maker of the autonomous agent "Manus"), it bills itself as "your AI companion & expert." It brings chat, search, summarization, translation, writing, image/video generation, and coding together, usable from a browser extension, web app, desktop, and mobile. Lately it has expanded into agentic features that carry out tasks autonomously.
At Monica's core is a multi-model assistant where you switch models by purpose. From the left menu you can choose chat, search, read, write, image (Artist), translate, and memo, and combine them with file uploads and web search. As a browser extension, it can summarize or translate the web page you're viewing on the spot.

Switch the latest models, and use tools together
What sets Monica apart from a single-model chat AI is that you can use multiple models and many tools from one entry point. You can switch among the GPT-5 family, the Claude 4 family, and the Gemini 3 family, as well as image/video models like Nano Banana, Sora, and Veo, and coding models, by purpose. Tools like summarize, translate, ChatPDF, mind maps, and image/video generation are laid out in a list so you can call up what you need right away.
The tool set gathers full-page processing, writing, grammar check, translation, AI detection, ChatPDF, mind maps, search, and more. On top of that, an AI agent, Deep Research, slide creation, Image Studio, and coding (Monica Code) are all available from one account.

Pricing
It is free to start, and paid plans are four tiers—Free / Pro / Max / Ultra ("Unlimited" was renamed to Max). Amounts are in USD, and annual billing is cheaper. Advanced features consume "advanced credits."

Advanced credits are consumed by Deep Research, slide creation, Image Studio, image/video generation, ChatPDF, and more, and reset monthly. Accounts are for individual use; sharing or multi-user use is not intended (it is sometimes described as "commercial use OK," but there is no explicit commercial-use grant). Pricing may change, so check the [official pricing page](https://monica.im/pricing) for the latest (as of August 2026).
How it differs from other AI assistants
Monica's strength is that it bundles multiple models and tools into one subscription, usable from a browser extension and every device. Its scope and breadth of entry points differ from single-model chat AIs.
| Aspect | Monica | ChatGPT | Poe |
|---|---|---|---|
| Models | Switch among several | Mainly first-party | Switch among several |
| Entry points | Extension, web, app, IDE | Web, app | Web, app |
| Agent | AI agent, research | Yes | Bot-focused |
The first-party-focused ChatGPT, the multi-model Poe, and the all-in-one Genspark AI are comparison points. If you want multiple models and tools in one place and quick use in the browser, Monica is a strong choice.
