An AI browser agent that does the clicking.
Say what you need in one sentence. Hark works through the website in front of you — step by step, in plain sight — and stops for your approval before it books, buys, sends or deletes.
What you get
Built to save you real minutes.
Clicks and navigates
Buttons, links, menus, date pickers and dropdowns — Hark operates the page the way you would.
Types and fills forms
Give Hark the details once and it completes long forms field by field.
Shows every step
A live list of what Hark has done and what it is doing now. Stop it at any time.
Asks before final steps
Send, submit, book, order, pay, subscribe, delete — each needs your explicit approval.
Leaves secrets to you
Passwords, one-time codes and card numbers are never read or typed by Hark.
Works in your tab
No separate cloud browser. Hark acts in the tab you start from, with the logins you already have.
What a browser agent actually is
A chatbot tells you how to do something. A browser agent does it. Hark looks at the page — its buttons, links, form fields and visible text — decides the next step toward your goal, performs it, and looks again. That loop repeats until the task is done or Hark needs you.
Hark’s agent uses a fixed set of actions that are built into the extension: click, type, choose an option, scroll, press a key and open a web address. The AI model only chooses which action comes next. No code from a server or from the model is ever run in your browser. If you are new to the idea, start with What is an AI agent?
Designed around approval, not autonomy
The hard problem with agents is not capability, it is trust. A web page can contain text that tries to trick an AI into doing something you never asked for — a risk known as prompt injection. Hark’s answer is simple and visible: the agent works only in the tab where you started the task, and every step with real-world consequences waits for you. You see exactly what will be clicked before it is clicked.

What it is good at — and what it is not
Hark shines at short, well-defined errands on a single site: reserve a table, fill a registration form, find the cheapest item on a page, unsubscribe from a newsletter, change a setting buried three menus deep. It is not a tool for scraping thousands of pages, bypassing CAPTCHAs or paywalls, or running unattended overnight — and it will ask you to complete logins, verification and payment steps yourself.
How to use it
4 steps, about a minute.
Open the site where the task happens
For example a restaurant’s booking page or the form you need to fill.
Switch to Agent and describe the task
Be specific about dates, times, names and quantities.
Watch the steps
Hark lists each step as it goes. Press Stop whenever you like.
Approve the final step
Hark shows what it wants to click — for example “Book now” — and waits for your OK.
FAQ
Questions, answered
What can Hark’s agent do on a website?
It can click buttons and links, type into fields, choose options from dropdowns, scroll, press keys and open web addresses in the tab where you started the task. That covers most everyday errands: bookings, forms, price checks, settings changes and unsubscribes.
Will Hark buy something without asking?
No. Any step that sends, submits, books, orders, pays, subscribes or deletes requires your approval. Hark shows the exact action and waits. When a login, verification or payment detail is needed, it asks you to do that step yourself.
Does the agent work on every website?
It works on most ordinary websites. Some sites block automation, use unusual custom controls or require steps only a human can do (such as CAPTCHAs). Hark will tell you when it cannot continue. Use the agent only on sites where automated use is allowed.
Does the agent run in the cloud?
No. Hark acts in your own Chrome tab, so it uses the session and logins you already have. Page snapshots are sent to our server and AI provider only to decide the next step and are not stored.
Do I need Hark Pro for Agent mode?
Agent mode is included in the free plan, within the limit of 1 request per day. Hark Pro makes Agent tasks unlimited. See pricing.
