An OS designed to take over your computer

Tech companies have spent two years telling us that chat boxes are the future of computing. But typing prompts into a blank terminal fifty years after the command line was invented does not exactly feel futuristic.

Hark, a startup launched less than a year ago by serial founder Brett Adcock, is taking a different swing at the problem. The company just rolled out Hark Pro, pitching it not as another chatbot, but as a full-screen operating system designed to use your computer for you. It is available for free, with a paid subscription tier for heavy users.

While frontier labs chase artificial general intelligence, Hark says its ambitions are much more grounded. The platform runs on a model trained specifically for computer use. In its launch materials, Hark is not playing nice either, explicitly telling users to cancel their ChatGPT subscriptions.

An assistant that actually clicks the buttons

Designed by former Apple staffer Abidur Chowdhury, Hark Pro takes over the whole screen with a dynamic background that mirrors your local time and weather. The center features a chat bar flanked by contextual action prompts and customizable mini-dashboards called panels.

Once hooked up to your email, calendar, hard drive, and payment methods, the assistant gets proactive. During an early demo, it surfaced pending expense approvals, unread emails that needed replies, and upcoming calendar appointments. It even identified an employee whose vehicle registration was expiring and went ahead to renew it directly through the California DMV website.

One of the most interesting UX choices is how Hark handles web automation. Instead of executing actions invisibly in the background, Hark Pro opens a small window that lets you watch the agent navigate, click, and fill out forms in real time. Chowdhury says showing the work is critical for building trust when agents are handling sensitive digital tasks.

Addressing privacy concerns, Hark claims it has no interest in selling ads or tracking personal social graphs like legacy tech giants. Looking further ahead, the startup is also planning to launch an AI-native hardware device in 2027, though Chowdhury was quick to dismiss wearable cameras as inherently creepy.

Why it matters

For regular users buried under administrative busywork, Hark Pro is a glimpse of what software should actually be doing. Mundane chores like paying DMV fees, sorting inbox backlogs, and filing corporate expenses are prime candidates for automation. If you deal with endless web forms, it is worth testing out the free tier right now, provided you are comfortable granting third-party access to your personal accounts.

Across the industry, this launch underscores an escalating pivot from raw conversational intelligence to agentic computer use. Making an LLM sound smart is table stakes today; the real battleground is end-to-end execution where software navigates the web without forcing you to step in halfway through. By telling users to ditch ChatGPT, Hark is betting that people care far more about getting tasks finished than having clever conversations.

In our view, Hark’s decision to show its web navigation inside a visible sub-window is a remarkably smart UX move. When an AI touches your credit card, black-box execution breeds anxiety, while a visible trail builds confidence. That said, relying on a model fine-tuned purely for UI actions means it might stumble on edge cases where deep reasoning is required, and convincing mainstream users to grant an early-stage startup full access to their files remains an uphill climb.
