Merlin AI is a browser extension and a website. With one account, you use several assistants: ChatGPT, Claude, Gemini, Mistral, and others. A keyboard shortcut opens a panel on the page you are viewing, to summarize it, reply to an email, or ask a question. You don’t need an account with each vendor.
Merlin AI 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 Merlin AI does
Who it’s for: people who want to try several assistants without piling up subscriptions, and who work mostly in their browser.
A panel on any website

Summarize an article or a YouTube video
Merlin summarizes an article, a web page, or a YouTube video. For a video, it points out the key moments.

Merlin AI pricing
Merlin publishes its prices in dollars. The pricing page did not load during our check: the Pro price comes from the website’s home page. In the French App Store, “Merlin Unlimited” is sold for €17 per month. Refunds are possible only within 3 days of purchase.
| Plan | Price | Who it’s for |
|---|---|---|
| Free Recommended to start | $0 | Trying it, light use |
| Pro | $19 per month, billed yearly | Daily use, one person |
| Teams | Price not checked, per user | Teams of 5 or more |
What the free plan includes
102 queries credited each day. A question to a light assistant uses one. A question to an advanced assistant uses many more: the vendor gives the example of 30 for a single request. So the allowance goes very fast with the best assistants.
Nova’s advice
Stay on the free plan to compare assistants on your real tasks. If one assistant clearly stands out, subscribing to it directly will often be simpler and more predictable than a Merlin subscription.
A first try, in 4 minutes
Your data. Merlin records your requests, your files, and information about the pages where you use it. Its policy does not say whether this data is used to train an AI.
What it does less well
- Query counts are hard to predict: a single request to an advanced assistant can cost 30 queries. The “unlimited” plan has caps too.
- Privacy is the weak point: a lot of data collected, and no clear answer on training. Avoid it for sensitive HR, financial, or legal matters.
Summarize a web page without leaving the tabMerlin AI- Open an article or a long page, for example a supplier’s terms.
- Press Ctrl + M (Windows) or ⌘ + M (Mac).
- Paste the prompt below into the panel and submit.
- Look at the top left to see how many queries this request used.
- Switch assistants in the menu and ask the same question again to compare the two answers.
The prompt to copy
Summarize this page in five points for my team. Then list what commits us: deadlines, penalties, termination terms. Flag anything that is unclear.
