Your personal AI agent in Chrome.
Hark reads your email, books things, tracks your stuff and runs tasks on websites — right in the side panel, and always with your approval.
- Free plan, no account needed
- Works in Gmail & Outlook
- Asks before final steps
Three modes, one side panel
An assistant that doesn’t just answer — it acts.
Most AI tools stop at text. Hark reads what is in front of you, does the clicking and typing, and remembers what you need to follow up on.
Your inbox, handled
Open any email in Gmail or Outlook. Hark gives you the point in three lines, finds what you have to do and by when, and writes a reply in your reply box — ready to review and send.
- Summaries of long threads in seconds
- Replies drafted in the language of the email
- Tasks and dates sent straight to Tracker
Tasks, done for you
Describe a task in plain words. Hark clicks, types, scrolls and navigates in the tab you are on while you watch — booking a table, filling a form, comparing prices, unsubscribing.
- Works on the site you already have open
- Shows every step as it happens
- Asks for your approval before anything final
Never lose track
Orders, bookings, bills and deadlines are scattered across emails and websites. Hark scans the page or email you choose and collects them in one list, sorted by date.
- One tap to scan a page or an email
- Overdue, upcoming and done at a glance
- Stored in your browser, not on our servers

Letting software click for you is a big deal. Hark is built so the decisions that matter stay with you. How Hark handles your data.
Nothing final happens without your OK
Before Hark sends, submits, books, orders, pays, subscribes or deletes, it stops and shows you the exact step.
Never types passwords or cards
Logins, one-time codes and payment details are always left to you.
Reads only when you ask
No background reading of tabs, emails or history. Ever.
Chats stay in your browser
History, Tracker and settings are stored locally. We don’t keep your conversations.
Delete everything in one tap
“Delete all my data” clears your browser data and your anonymous server record.
How Hark compares
An agent without switching browsers.
AI browsers can act but want you to move your whole browsing life. Chat sidebars stay in Chrome but only talk. Hark does both jobs.

FAQ
Questions, answered
What is Hark AI Agent?
Hark is a Chrome extension that adds a personal AI agent to your browser’s side panel. It can chat, read the page or email you have open, draft replies in Gmail and Outlook, click and type on websites to finish tasks for you, and keep a Tracker of your orders, bookings, bills and deadlines.
Is Hark free?
Yes, there is a free plan with 1 AI request per day, so you can try every mode. Hark Pro removes the daily limit: $5.99 a week with a 2-day free trial, $14.99 a month or $39.99 a year. See pricing.
Do I need a new browser to use an AI agent?
No. Hark is an extension, so it works inside the Chrome you already use, with your tabs, bookmarks and logins. That is the main difference from AI browsers such as Comet, Dia or Opera Neon, which ask you to switch browsers. See AI browser vs AI extension.
Will Hark buy or send something without asking me?
No. Before any step that sends a message, submits a form, books, orders, pays, subscribes or deletes, Hark shows you exactly what it is about to do and waits for your approval. It never types passwords, one-time codes or card numbers — you complete those steps yourself.
Does Hark read my pages and emails all the time?
No. Hark reads a page or an email only when you ask: when you turn on “Use this tab”, tap an action such as “Summarize this email”, or start an Agent task. It never reads tabs in the background. Details are in the Privacy Policy.
Which email services does Hark work with?
Hark works with Gmail and Outlook on the web. It reads the email that is open in your tab, summarizes it, finds tasks and dates, and puts a drafted reply into the reply box so you can review and send it yourself. It does not connect to your mailbox through an API.
Which AI models does Hark use?
Hark offers two modes: Fast for quick everyday answers and Smart for deeper reasoning on harder tasks. Both currently run on OpenAI models. Your content is not used to train AI models.
Which languages does Hark support?
The interface is available in English, German, Spanish, French, Italian and Portuguese (Brazil and Portugal). Hark answers in the language you write in.
