Brett Adcock's Hark Launches Hark Pro, an AI Assistant That Uses Your Computer for You

Hark, the startup founded less than a year ago by serial founder Brett Adcock, has released Hark Pro today — a full-screen AI personal assistant built on a model trained specifically for computer use, with free access and a paid subscription tier for heavy users.

The launch puts Hark in direct competition with Muse, Instinct and Dots, all of them hunting for the user experience that turns an AI personal assistant into a must-have product.

The company defines its mission narrowly: building a user interface for AI, not creating AGI or curing cancer. Hark Pro's core function is simple to state. It uses your computer for you. Rather than shipping an app, Hark's goal is to create an operating system for the AI computers of the future.

What does Hark Pro actually do?

The product is a full-screen experience with a homepage. It features a central chat dialog, a feed of suggested actions, and visualizations the company calls "panels" — mini-dashboards for topics the user cares about. The background is custom imagery tailored to local weather and time of day.

As with other AI assistants, users configure Hark Pro to access their digital life: email, calendar, hard drive, credit cards. It then handles digital tasks and answers classic chatbot questions.

Abidhur Chowdhury, a former Apple staffer who leads design at Hark, demoed the product. It proactively asked him about expenses he needed to approve, emails needing replies, an upcoming meeting, and a flight it offered to book. "I know the flight thing is put to death," he said, grinning.

The harder problem for these apps, he acknowledged, is users coming up with tasks the assistant can actually accomplish. Chowdhury said he was impressed when the assistant recently recognized that a colleague needed to renew a car registration at the California DMV — and handled it through the agency's website.

How does Hark build trust?

One notable UX choice: Hark shows the user how the agent navigates the web in a small window, something most AI assistants perform invisibly. Chowdhury says this is intended to build trust that the agent is doing the right thing.

That trust argument is central. Part of Hark's pitch is that it is not Meta or OpenAI. "We're not here to like sell you ads and steal your data," Chowdhury says. To truly leverage these models, users will need to share their entire digital lives — raising the question of whether they would let a company like Meta build detailed profiles of their friends and family.

Asked about profiling, Chowdhury says: "We are doing work to understand you, and be helpful for what you need, but it's really like task related — it's really about how Hark can take something off your plate and be useful."

He argues Hark Pro's differentiator is the effort to fully substitute for your computer — and his belief that it simply works better. "Please compare it to the others, be critical," he says. "It might not be faster than Muse, but it will give you a better result, and it will work end-to-end instead of asking you to take over at a point."

What are the open questions?

The model question remains unresolved across the category. Hark's model is explicitly trained for computer use, making it faster and cheaper at those tasks. What's not clear is how much it trades away the broader knowledge and capability of a frontier LLM.

Software is only half the promise. Hark says it will release an AI-native device to support its software in 2027. The company remains cagey about the form factor, with Chowdhury bemoaning the "creep factor" of wearable cameras. "I will give you this: the first product that we're building is a product that's never ever existed before," he says — a claim the market will judge in two years.

He frames the motivation bluntly: "It's so hilarious to me that you have AI now, you have a chatbot, and you type stuff in with a keyboard. Fifty years later and the future of computing is still a terminal." Whether Hark replaces that terminal or joins the pile of retread attempts is the bet Adcock has now placed.
