Monica pricing, use cases, and first steps
Monica is an extension for Chrome and Edge. It adds a panel to the side of your browser. In that panel, you chat with several well-known assistants (GPT, Claude, Gemini, Grok, Mistral) without switching tabs. Monica summarizes the open page, translates, helps you draft a reply, and creates images. It also comes as a desktop app and a phone app.
Monica has a free plan. The recommended plan to start with: Free, €0. Prices checked on October 3, 2026 on the vendor’s official page.

What Monica does
Who it’s for: people who spend their day in the browser: reading articles, answering emails, looking things up, translating a page.
Summarize a page, a PDF, or a YouTube video
Monica reads the open page, a PDF, an image, or a screenshot, then gives you the key points. For a YouTube video, the summary lists the key moments with their timestamps.
Write and reply in any text field
The “Write” feature has two modes: “Compose” to write a text, “Reply” to answer a message. You set the length, format, tone, and language. A small writing icon also appears in the text fields of websites.
Also
- Translate a page and keep the original
- Select text to act on it
- Search with sources
- Create an image or a short video
- Set pages and documents aside
Monica pricing
When we checked, the amounts on the website’s pricing page were not readable: we could not record those for the Max and Ultra plans. On the French App Store, the plans above Pro are called “Pro+” (€22.99 per month) and “Unlimited” (€29.99 per month). Credits can also be bought separately: 4,000 credits for $10. Payments are non-refundable, except for the 14-day right of withdrawal for European Union residents.
| Plan | Price | Who it’s for |
|---|---|---|
| Free Recommended to start | €0 | Exploring, occasional use |
| Pro | €9.99 per month (price seen on the French App Store); €99 per year | Daily use |
| Max | Price not recorded | Heavy use |
| Ultra | Price not recorded | High-volume image and video creation |
What the free plan includes
40 basic queries per day, reset every day at midnight (UTC). No advanced queries, so no access to the most capable assistants or to image creation. Three connected devices at most.
Nova’s advice
Stay on the free plan: 40 queries per day are enough to summarize, translate, and rephrase. Only pay if you hit that limit several days in a row. If you already subscribe to an assistant such as ChatGPT or Claude, Monica partly duplicates it.

Your data. Your data is stored in the United States, and Monica passes your requests on to the vendors of the assistants you choose.
What it does less well
- Monica does not build its own assistants: it resells access to other companies’. The versions on offer and the limits change often, and the most capable ones use credits.
- The system of basic queries, advanced queries, and credits is hard to follow. An image costs from 3 to 80 credits, a video up to 1,600.
Summarize an article without leaving the pageMonica- Open a long article you need to read for work: a study, a news article, a documentation page.
- Press ⌘ + M on Mac or Ctrl + M on Windows. The Monica panel opens on the right.
- Paste the prompt below into the input field and send it.
- Read the summary, then ask a specific question about one point in the article.
- Check any figures you plan to reuse against the page itself.
The prompt to copy
Summarize this page in five points for a busy colleague. Then add the three most important figures and what this changes in practice for a sales team.
