Overview
Merlin is an AI assistant available through browser tools and mobile apps. It brings multiple models into chat, writing, webpage and video summaries, document assistance, and image tasks. Free access has usage limits, while paid and team subscriptions add a larger allowance and collaboration options.
Our take
Merlin is a browser assistant covering chat, writing, summaries and research, with limited free usage above paid tiers. Browser assistants are convenient precisely because they see what you see, which is also the reason to think carefully before installing one on a work machine — that is a very broad permission.
Worth it if
People who want assistance available on any page without switching to a separate tab.
Look elsewhere if
Machines handling confidential client or internal data, unless the terms have been checked.

❓ Frequently Asked Questions
What does a browser assistant actually have access to?
Typically the content of pages you use it on, which can include internal systems, client records and anything else on screen. Check what is transmitted, what is retained, whether content is used for training, and whether your employer permits it. This is a broader permission than any standalone app requires.
Does it slow the browser down?
Extensions that inject scripts into every page have a measurable cost, and several running together compound it. If pages have become sluggish, disabling extensions one at a time is more productive than any other debugging — and usually reveals a couple you had forgotten were installed.
