What is Monica?
Monica is an all-in-one AI assistant that gives you several leading AI models in one place: a browser sidebar, a desktop app and a mobile app. It is made by Butterfly Effect, and its website says 10 million people use it.
Monica AI works by reading the page, file or video you have open and sending your request to the model you choose, so you get help without switching tabs.
Key Features
Monica’s key features are multi-model AI chat, one-click summaries of web pages, PDFs and videos, writing help, translation, AI search, image and video generation, and a coding assistant, across a browser sidebar, desktop and mobile apps.
- Multi-model chat: Switch between models from OpenAI, Anthropic and Google in one conversation window. Monica’s site also lists Grok and Mistral models, so you can compare answers without separate accounts.
- Page, PDF and video summaries: Condenses articles, documents and YouTube videos in one click, which saves reading or watching the full source before deciding if it is useful.
- Writing help: Drafts, rewrites and replies to emails and posts on any site from the sidebar, so the text lands where you are already typing.
- Translation: Translates selected text or whole pages inside the browser, without copying content into a separate translator.
- AI search: Answers questions with sources from the web, which the site calls smart search.
- Image and video generation: Creates visuals from text prompts. Monica’s site lists image models such as DALL-E 3, Flux and Ideogram and video models such as Sora 2 and Veo 2.
- Extra creative tools: Includes watermark removal, logo generation, photo-to-cartoon conversion, mind maps, podcast generation and audio-to-text conversion, according to the official site.
- Monica Code: Adds AI coding help inside VS Code and JetBrains editors, alongside code generation in the main chat.
Pros
Monica’s main advantages are access to models from several AI companies under one account, a sidebar that works on any website, a broad toolset, apps on six platforms and a free plan to test it.
- Many models, one subscription: One plan covers models from OpenAI, Anthropic, Google and others, which would otherwise need a separate subscription to each assistant.
- Works where you browse: The sidebar opens on any website in Chrome and Edge, so you get help on the page you are reading without switching tabs.
- Broad toolset: Chat, summaries, translation, writing, search, images and video sit in one product, which replaces several single-purpose extensions.
- Cross-platform: Available as Chrome and Edge extensions, macOS and Windows desktop apps, and iOS and Android apps.
- Free plan: Monica is free to start with a daily usage limit, so you can test the sidebar and core tools before paying.
- Large user base: Monica’s website says 10 million people use it and shows a 4.9 out of 5 rating on the Chrome Web Store.
Cons
Monica’s main drawbacks are a daily cap on the Free plan, a credit system for advanced models, plan prices we could not confirm on its pricing page, and an extension that needs access to the pages you visit.
- Daily cap on Free: The Free plan has a daily usage limit, and regular users will reach it quickly.
- Prices are hard to confirm: Monica’s pricing page did not show plan prices when we checked. Third-party listings quote about $9.90, $24.90 and $99.90 a month for Pro, Max and Ultra.
- Credit system: Advanced models and media tools consume monthly credits. Third-party listings report 1,500 credits on Pro, 4,500 on Max and 20,000 on Ultra, which reset each month.
- Browser permissions: The extension needs access to the pages you visit in order to read and summarise them, so check the privacy policy before using it on sensitive sites.
- Chrome and Edge only: Monica’s site lists browser extensions for Chrome and Edge. Firefox and Safari users have to rely on the desktop or mobile apps.
- Individual accounts: One third-party listing says accounts are for individual use, so the plans are built for single users, not teams.
Who is Using Monica?
- Students and researchers: Summarise long articles and papers.
- Writers and marketers: Draft content and emails in the browser.
- Professionals: Translate and extract key points from reports.
- Developers: Explain code on documentation pages.
