Hark AI: What Hark Pro Does, What It Costs, Early Reports
Hark Pro is a personal AI assistant from Hark, the AI lab that Figure founder Brett Adcock started in late 2025. It launched on October 6, 2026, free on the web, iOS and Android. You ask for something in one chat thread, and when the job needs the web, Hark opens a browser on its own cloud computer and does it: orders the food, pays the bill, books the table.
Meta’s Muse, OpenAI’s Dots and Instinct sell the same idea. Hark’s pitch is the interface, a computer-use model it trained itself, and a promise never to train on your data. Adcock’s goal, per Fast Company, is for Hark to handle everything he does on a computer “so that I never have to use a computer again.”
What Hark Pro does
You talk to Hark in one long chat, with separate Projects for bigger jobs like a move. The home screen holds two features most chatbots lack:
- Action Buttons. Hark reads your email and lists your to-dos with a button on each: “Pay” a bill, “Cancel” a subscription, “RSVP” to an event. Tap it and Hark does the task start to finish.
- Panels. Describe a tracker and Hark builds a small app for it, pulling data from services like Strava, Spotify or Venmo.
Behind both sits Handoff, Hark’s computer-use agent. For each request it starts a virtual computer with its own browser, logs in to sites with your saved credentials, and clicks through the task, running up to six browsers at once. You watch it in a small window and can cancel at any point.
Hark also remembers what you tell it, runs tasks on a schedule, and connects directly to Google Workspace, Microsoft 365 and Slack. Passwords and card numbers sit in an encrypted vault Hark calls Secured by Hark, which it says no person at the company can open.
It sends email from your accounts, in your name, and by default asks before it sends anything or spends money.
Who is behind Hark, and the money
Adcock founded Archer Aviation, the electric air taxi company, and Figure, the humanoid robot maker he still runs. He seeded Hark with $100 million of his own money. In May 2026, before shipping anything, it raised more than $700 million at a $6 billion valuation, led by Parkway Venture Capital with NVIDIA, AMD Ventures, Intel Capital, Qualcomm Ventures and Salesforce Ventures among the investors.
Design is led by Abidur Chowdhury, who introduced the iPhone Air at Apple’s September 2025 keynote and left Apple two months later.
The app is half the plan. Hark says its first device ships in 2027, with AT&T supplying connectivity. Chowdhury has ruled out camera glasses and wearable pins but has not said what it is.
Hark Pro pricing
| Tier | Price | What you get |
|---|---|---|
| Hark Pro | Free | Every feature, with a usage cap |
| Hark Pro² | $20/month | 2x the free usage |
| Hark Pro³ | $100/month | 10x the free usage |
Checked October 7, 2026. Hark lists monthly prices only, with no annual toggle.
Paying buys usage, nothing else. Hark does not say what the free cap is in messages or minutes; its pricing page says the $100 tier could “plan 50 weddings.” Optional auto top-ups buy more credits, and unused ones are not refundable.
Adcock promised the first 100,000 sign-ups a paid plan for free, and waitlist users report getting a month of it. His day-one numbers show 143,244 daily active users within 24 hours.
What the terms say
- No training on your data. The privacy policy says your inputs, outputs, memory and connected account data are not used to train AI models, with no opt-out needed. Hark can still use your content to improve the service and review it for safety.
- It acts in your name. Messages Hark sends for you are your responsibility “as if you had sent them yourself.” Where a person is likely to read them, Hark will identify itself as an AI acting for you.
- Retention. Your data is kept for the life of your account and deleted or de-identified when you close it, apart from legal holds and backups.
- Arbitration. US users agree to binding individual arbitration and waive class actions, with 30 days after sign-up to opt out.
You must be 18 or older.
What early users report
Adcock counted 1.5 million messages and 130,208 Handoff sessions in the first 24 hours. The wins people posted are concrete: an AppleCare subscription one user had failed to cancel for two years, finally cancelled, and an inbox cleared of more than 1,000 emails.
The complaints are concrete too:
- The free cap runs out fast. One user said his usage was exhausted in 10 minutes, and Adcock replied that he was looking into it. Another said the daily limit was fine but the monthly one felt low, with no way to see how much was left.
- Launch bugs. A tester found the GitHub connector broken on day one, along with “quite a lot of bugs,” and Hark said it was on it. Another reported browsers that “keep crashing.”
- Speed. In Gizmodo’s demo, a DoorDash order took several minutes before Handoff asked to confirm payment. One user called it the “slowest personal ai agent.” Chowdhury conceded to TechCrunch that it “might not be faster than Muse” but gives a better result.
- No phone calls yet. Asked why Hark can’t make phone calls, Adcock replied, “We’ll get there.”
Hark also calls Handoff “independently verified” as the best computer-use model. The link goes to its own research post, which cites the public Online-Mind2Web leaderboard, where Handoff ranks first, plus two benchmarks Hark ran in its own setup.
Hark vs Muse, Dots and Instinct
| Price | Where you use it | What stands out | |
|---|---|---|---|
| Hark Pro | Free, $20, $100 | Web, iOS, Android | Action Buttons, Panels, no training |
| Meta Muse | Free, $20, $100 | App, web, WhatsApp, Mac | Small-business connectors |
| ChatGPT Dots | ChatGPT Pro, from $100 | ChatGPT, Slack, Teams | Thousands of ChatGPT plugins |
| Instinct | Free invite-only beta | iMessage, WhatsApp, phone | Lives in your texts |
Hark and Muse match on price to the dollar. The split is posture: Muse opts you in to AI training by default, and Hark promises it never trains on your data. For the wider field, see our Hark alternatives.
Where Carly fits
Hark is built for life admin: dinner, groceries, the subscription you forgot. It says it works for professional life too, but there is no team plan, and its Action Buttons wait for your tap.
If your to-do list is your inbox, calendar and clients, Carly is built for that job:
- It lives in your Gmail or Outlook. Carly drafts replies in your voice and sends them from your own address.
- It runs your real calendar. It finds times, sends invites and moves meetings.
- It starts on its own. Carly workflows run when an email lands from a specific sender, a lead form comes in, a meeting ends, or Monday morning arrives.
- It works for a team. Agents you build can run workflows for your whole team.
- It meets you where you are. On the web, by text message, by email, through the Carly plugin in ChatGPT, or the Carly connector in Claude.
Carly connects to thousands of apps, including HubSpot, Salesforce, Slack and Google Drive. Free Zapier-style workflows; AI agents from $35/month. Get started.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
