Monica

All-in-one AI assistant that routes to GPT, Claude, and Gemini from a browser sidebar, desktop, web, and mobile — chat, write, translate, search, summarize.

Monica is an all-in-one AI assistant that routes to frontier models — GPT-5.5, Claude, and Gemini — from a browser sidebar plus desktop, web, and mobile apps. The Free tier caps daily queries; Pro starts around $9.90/month ($8.30 billed annually) with 200 advanced-model queries and a monthly credit pool; Pro+ and the top Max tier add more. Best for people who want many models under one subscription.

What is Monica?

Monica is an all-in-one AI assistant that puts several frontier models behind a single interface. Instead of opening separate tabs for ChatGPT, Claude, and Gemini, you summon Monica from a browser sidebar — or from its desktop, web, and mobile apps — and choose the model that fits the task. It routes to GPT-5.5, Claude, Gemini, and Mistral for text, and to image and video models such as DALL·E, Stable Diffusion, and Sora 2 for generation. Around that routing layer it wraps everyday productivity tools: chat, writing and rewriting, real-time translation, web search with AI answers, and one-click summarization of web pages, videos, and PDFs.

Because the assistant lives in a sidebar, its strength is context: it can read the page or document you are already looking at and summarize, translate, or rewrite it in place. A no-code bot builder lets you save reusable prompts and workflows, and a separate developer platform exposes API access for programmatic use. Since early 2026 Monica has metered its premium features through an Advanced Credits system, a monthly pool you can spend across models of differing cost, with top-ups available if you run out. It is developed by Butterfly Effect Pte. Ltd.

Who is it for?

Monica is aimed at people who want breadth over depth — access to many models and everyday AI tasks under one subscription — rather than a single specialist tool. Its free tier is enough to evaluate the sidebar, but the multi-model access and credit pool that make it worthwhile arrive with the Pro plan and above. It is a generalist assistant, so users who need a best-in-class experience for one narrow job (agentic coding, deep research) may still prefer a dedicated tool.

  • Knowledge workers and researchers who summarize long articles, reports, and PDFs and want that to happen on the page they are already reading.
  • Multilingual writers and marketers who translate, rewrite, and draft content across languages without switching apps.
  • Model comparison shoppers who would rather pay once and switch between GPT, Claude, and Gemini per task than maintain several subscriptions — a similar promise to aggregators like Poe.
  • Casual and mobile users who want a capable assistant across browser, desktop, and phone, and only occasionally need the heavier advanced models.
  • Developers who want the same multi-model access programmatically through Monica’s API.

  5. 05 Running quick web searches that return AI-generated answers with real-time results

Pros and cons

Pros and cons of Monica
Pros Cons
One subscription unlocks many frontier models, avoiding separate ChatGPT, Claude, and Gemini logins Tier lineup and credit counts change often — the top Max plan (formerly Unlimited) is in beta and its allocations have shifted between sources
Works everywhere it's needed — browser extension, desktop apps, web, and mobile Advanced-model use is metered by credits, so heavy users can exhaust the monthly pool before it resets
Strong at in-context tasks: summarize, translate, and rewrite directly on the page you're reading Not a dedicated coding tool — for serious agentic coding, using Claude or a code-native editor directly is a stronger choice
Free tier needs no payment and covers light daily use Routing to third-party models means output quality and availability depend on providers Monica does not control

How people make money with Monica

  • Offer a 'set up your AI stack' service for freelancers and small teams — configure Monica's sidebar, custom bots, and model routing so clients get GPT, Claude, and Gemini access under a single Pro subscription instead of several separate logins
  • Bundle multilingual content and summarization work — use Monica's translation and ChatPDF tools to turn long reports into localized briefs and bill clients per deliverable while one Pro or Pro+ plan covers the tooling

Frequently asked questions

Is Monica free?

Yes. Monica has a permanently free plan with a limited number of daily basic-model queries and restricted access to advanced models. It covers light chat, translation, writing, and page summarization, but has no monthly advanced-credit pool. Paid plans start with Pro at around $9.90/month.

Which AI models does Monica use?

Monica routes requests to multiple frontier models through one interface, including GPT-5.5, Claude, Gemini, and Mistral, plus image models like DALL·E and Stable Diffusion and Sora 2 for video. You can pick a model per task rather than being locked to one provider.

How much does Monica Pro cost?

Pro is around $9.90/month, or about $8.30/month billed annually. It includes roughly 5,000 daily basic-model queries and 200 advanced-model queries per month plus a monthly advanced-credit pool, along with unlimited summarization and the full writing and translation toolkit.

What are Advanced Credits?

Advanced Credits are a monthly pool that fuels premium features such as image generation, video creation, extended chat context, full-text ChatPDF reading, and AI agents. Credits reset on the first day of each month, and users can buy top-up credits if they run out.

Does Monica have an API?

Yes. Monica offers a separate developer platform for programmatic API access, distinct from the consumer subscription plans. This lets developers integrate Monica's model routing into their own applications.

Is Monica good for coding?

Monica can route coding questions to models like Claude and GPT, which is handy for quick help inside the browser. But it is not a code-native tool — for serious agentic coding, using Claude or a dedicated code editor directly gives stronger, more reliable results.

Who develops Monica?

Monica is developed by Butterfly Effect Pte. Ltd. The same company builds a separate autonomous agent product, so Monica the assistant should not be confused with that distinct tool.
