Hark Launches a Privacy-Focused AI Personal Assistant

Background: The Search for an AI Assistant Interface

Tech companies from Muse to Instinct to Dots have been chasing the user experience that could turn an AI personal assistant from a novelty into a must-have product. The common test is simple but difficult: can the assistant do enough of a user’s digital work without asking the user to babysit every step?

Hark Pro, released widely today by startup Hark, enters that race less than a year after the company was founded by serial founder Brett Adcock. The company’s stated mission is narrower than the frontier-lab dream of creating AGI or curing cancer. It wants to build a user interface for AI. Rather than an app, Hark’s goal is to create an operating system for the AI computers of our future. Its foundation is a model trained specifically for computer use, and the product is designed to use a user’s computer for them.

Development: From a Free Assistant to a Full-Screen Home

Hark Pro is available for free, with a subscription tier for heavy users. The interface is a full-screen experience rather than a simple chat window. It opens on a homepage with a central chat dialog, a feed of prompts for actions the assistant might take, and visualizations the company calls panels that work as mini-dashboards for things the user is interested in. The background is a piece of custom imagery tailored to local weather and time.

Access mirrors other AI assistants: users configure Hark to reach their digital life, including email, calendar, hard drive, credit cards, and similar services. From there, it can take on digital tasks as well as field classic chatbot questions. Abidhur Chowdhury, a former Apple staffer who leads design at Hark, demoed the product by showing it proactively asking him about expenses he needed to approve, emails he needed to respond to, a meeting with this reporter, and a flight he needed to book. He grinned and admitted, “I know the flight thing is put to death.”

That demo also points to a broader challenge: one of the harder things for users is actually coming up with useful tasks the assistant can accomplish. Chowdhury said the assistant recently impressed him when it recognized that a colleague needed to renew their car registration at the California DMV and handled it through the agency’s website. One notable user-experience choice is showing the user how the agent navigates the web in a small window. Most AI assistants perform browsing without surfacing it; Chowdhury says Hark displays it to build trust that the agent is doing the right thing.

Latest Progress: Trust, Trade-Offs, and the 2027 Device Plan

That trust-building matters because part of Hark’s pitch is that it is not Meta or OpenAI, because “we’re not here to like sell you ads and steal your data,” Chowdhury says. To leverage the models fully, users will need to share their entire digital lives, which raises very real cybersecurity concerns and questions about detailed profiles of friends and family. Asked about profiling, Chowdhury said Hark is doing work to understand users in a task-related way, to help take something off their plate and be useful.

What sets Hark Pro apart, in the company’s telling, is the effort to fully substitute for the user’s computer, plus the belief that it just works better. Chowdhury’s challenge is direct: “Please compare it to the others, be critical,” Chowdhury says. He said, “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.”

One open question is what kind of model best suits the AI personal assistant. Hark’s model is explicitly trained for computer use, which makes it faster and cheaper at those tasks, but it is not clear how much broader knowledge and capability from a frontier LLM it is trading away.

The software is only half of the promise. Chowdhury, who made his name designing devices at Apple, said Hark plans to release an AI-native device to support its software in 2027. The company is still cagey about the form, and Chowdhury bemoaned 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. The question is whether that device will be truly novel or a retread, and whether Hark can pair the assistant with new hardware without keeping users in a keyboard-and-screen world. As Chowdhury puts it, “Fifty years later and the future of computing is still a terminal.”
