Frequently Asked Questions
What is Monica AI and what does it do?
Monica is an all-in-one AI assistant built by Stack Network Limited that runs as a browser extension in Chrome and Edge, plus desktop apps for Windows and macOS and mobile apps for iOS and Android. It provides access to GPT, Claude, Gemini, and other models in a persistent sidebar that activates with Ctrl+M on any webpage. Core capabilities include chat, web page summarization, PDF analysis, writing assistance, translation, and image generation.
How much does Monica AI cost?
Monica has a free plan with daily credit limits. The Pro plan costs $9.90/month ($8.30/month billed annually) and includes 5,000 daily basic model accesses and 200 advanced model accesses per month. Pro+ is $19.90/month with higher credit allocation. The Unlimited plan is $16.60/month billed annually. Note that multiple users report the Unlimited plan has undisclosed caps that can be hit within a day of heavy use.
What are the main features of Monica AI?
Monica's key features include a multi-model AI sidebar (GPT, Claude, Gemini, Grok), contextual webpage summarization, YouTube video analysis, over 80 writing templates, in-browser text translation and rephrasing, PDF document Q&A, Gmail reply generation, and cross-platform sync across browser, desktop, and mobile. The Ctrl+M hotkey activates Monica on any site without copy-pasting.
Is Monica AI free to use?
Yes, Monica has a free plan that includes access to basic AI models with daily credit limits. The free tier is functional for light use — chatting, basic summarization, and some writing tasks. Advanced models like GPT-4o and Claude require a paid plan, and image or video generation is gated behind Pro and above.
What are the best alternatives to Monica AI?
The closest alternatives to Monica are MaxAI.me and Merlin, both of which offer browser-based AI sidebars with multi-model access. Perplexity AI is better if your primary need is AI-powered search and research rather than writing assistance. For users who want pure writing help, Notion AI or Grammarly are more focused options. ChatGPT Plus and Claude.ai cover the core chat use case but lack the browser sidebar integration.
Who is Monica AI best for?
Monica is best for content marketers, researchers, and multilingual professionals who spend most of their working day in a browser and want AI assistance without switching tabs. It suits users who want access to multiple AI models under one subscription rather than paying for each separately. It is not a good fit for developers needing a reliable API with clear rate limits, or enterprise teams requiring admin controls, SSO, and data compliance guarantees.
Does Monica AI have an API?
Yes, Monica has a developer API platform at platform.monica.im that allows teams to integrate its AI capabilities into their own products. Full API documentation and pricing for API access are available on the platform page. The API aggregates multiple underlying models, similar to the consumer product, though enterprise-grade SLA and rate limit guarantees are not prominently documented.
