Everything people ask about Hark.
Short, honest answers about what Hark does, how the agent stays safe, your privacy and billing.
General
What is Hark AI Agent?
Hark is a Chrome extension that puts a personal AI agent in Chrome’s side panel. It chats about the page or email you have open, completes tasks on websites in Agent mode and keeps a Tracker of orders, bookings, bills and deadlines.
How do I open Hark?
Click the Hark icon in Chrome’s toolbar or press Alt+Shift+H. If you do not see the icon, click the puzzle icon in Chrome and pin Hark AI Agent.
Do I need an account?
No. Hark works without sign-up. A random, anonymous install ID is used to apply the free-plan limit and link a purchase to your browser.
Which browsers are supported?
Google Chrome on Windows, macOS, Linux and ChromeOS. Chrome on phones does not support extensions.
Which languages does Hark speak?
The interface is available in English, German, Spanish, French, Italian and Portuguese. Hark can read and answer in most major languages.
Which AI model does Hark use?
Hark uses OpenAI models through OpenRouter: a fast model for everyday questions and a smarter model for harder tasks, which you can choose in the panel.
Agent mode
What can the Agent do?
It clicks, types, chooses options, scrolls and navigates in the tab where you start a task — booking a table, filling a form, comparing products, unsubscribing from a newsletter.
Will Hark buy or send something without asking?
No. Before any step that sends, submits, books, orders, pays, subscribes or deletes, Hark shows what it is about to do and waits for your approval.
Does Hark type passwords or card numbers?
Never. Login, verification and payment steps are handed to you; Hark can continue after you finish them.
Why did the Agent stop?
Some websites block automation, use unusual widgets or need a login. Hark tells you what it could not do so you can finish that step or change the request.
Privacy
Does Hark read my browsing in the background?
No. Hark reads a page or email only when you press a button, use the right-click menu, turn on “Use this tab” or start an Agent task.
Is my data used to train AI?
No. Your content is used only to answer you and is not used to train AI models.
Where is my chat history stored?
In your browser’s local extension storage. Settings → “Delete all my data” removes it, together with the anonymous record on our server.
Does voice input record my audio?
No. Speech is turned into text by Chrome’s built-in speech recognition. Hark never receives or stores audio — only the text you send.
Plans & billing
Is Hark free?
Yes. The free plan includes 1 AI request per day with every mode — Chat, Agent and Tracker — and needs no account. Hark Pro removes the daily limit.
How does the free trial work?
The weekly plan starts with a 2-day free trial. A payment method is needed to start it. If you cancel before the trial ends, you are not charged; otherwise the weekly price is charged and then every week.
How do I cancel?
Open Hark → Settings → Manage subscription, or use the link in your receipt email. Pro stays active until the end of the period you have paid for. Uninstalling the extension does not cancel a subscription.
Which plan is the best value?
The yearly plan: $39.99 a year works out to about $0.77 a week, compared with $5.99 on the weekly plan.
Can I use Hark Pro in more than one browser?
Yes. A subscription can be used in up to 3 browsers with “Restore purchase”, which sends a one-time code to the email you used at checkout.
Who processes the payment?
Dodo Payments is the merchant of record. It handles your card details, taxes and receipts — Hark never sees your card number.
Do prices include tax?
The price shown in the extension and at checkout is the price you pay, including applicable taxes. Checkout may show it in your local currency.
Can I get a refund?
If something went wrong with a charge, write to romanvlasovdev@gmail.com. Requests are reviewed individually and in good faith, and your rights under consumer law (such as the EU/UK withdrawal right) always apply. See the Terms of Use.
