Hark vs Gemini in Chrome: which one should you use?
Gemini is built right into Chrome, and its auto browse feature can complete tasks for you — if you are in the right country, on the right plan. Hark is an agent extension anyone can add to Chrome today.
Choose Gemini in Chrome if you are in the US, subscribe to Google AI Pro or Ultra and live in Google’s apps. Choose Hark if auto browse is not available to you, if you use Outlook as well as Gmail, or if you want a simple agent with no Google AI subscription.

- You use Outlook on the web, not only Gmail
- You want a tracker for what your emails and orders ask of you

- You prefer a built-in feature over an extension
Availability is the big difference
Gemini in Chrome started on desktop in the US in September 2025 and has been expanding. Its agent feature, auto browse, is rolling out gradually to personal Google AI Pro and Ultra subscribers in the US, in English, for adults — with daily limits of about 20 tasks on Pro and 200 on Ultra. Hark has no regional gate: if you can install extensions from the Chrome Web Store, you can use the agent, in seven interface languages.
Built-in vs independent
Being built in gives Gemini advantages no extension can match, such as access to several Google services at once. Being independent gives Hark a different kind of advantage: it works the same in Gmail and Outlook, it does not need a Google AI plan, and it reads a page only when you ask it to.
