Hark, the personal AI startup founded by Brett Adcock, has launched Hark Pro, a free web, iOS, and Android app that the company describes as "the operating system for your life."
Hark Pro remembers user context, operates a cloud computer on a user's behalf, and surfaces proactive actions across everyday tasks such as booking travel, paying bills, managing reminders, and handling online workflows.
The launch puts Hark into the crowded market for AI personal assistants, where startups and large technology companies are trying to move beyond chatbot interfaces toward agents that can use websites, connected accounts, files, calendars, and payment tools.
Hark Pro Moves Beyond a Chatbot Interface
Hark Pro is more than a place to ask questions. The app combines chat, projects, proactive notifications, and mini-app-style panels into a full-screen interface centered on a user's daily life. Hark says users can track work, school, travel, errands, subscriptions, expenses, entertainment, and other recurring tasks from one app, while learning user preferences, remembering relevant details, and applying that context when completing tasks.
The company's own examples include buying groceries, booking concert tickets, paying bills, storing logins, and spotting opportunities a user might otherwise miss. A user can also create scheduled tasks and reminders, while Hark can generate spontaneous suggestions when it identifies something that needs attention.
Hark builds its pitch around that proactive layer. Instead of waiting for a prompt, the app tries to recognize a useful next step and present it at the right time.
Handoff Lets Hark Use the Web on a User's Behalf
The technical center of Hark Pro is Handoff, Hark's computer-use agent. Handoff can operate up to six browsers at the same time and log into millions of websites on a user's behalf.
Many useful assistant tasks still require using websites that do not have clean APIs or agent-ready interfaces. Booking a reservation, renewing a registration, submitting an expense, buying tickets, or changing account settings often requires browser navigation, form filling, and confirmation steps. Hark gives the assistant its own secure computer so it can complete those workflows directly.
Outside the browser, Hark says the app can connect to Google and Outlook through APIs, read files, access external databases, and retrieve information through MCP tools. The system combines web browsing, account integrations, files, and user memory instead of treating each task as an isolated chat.
Hark shows users a small window of the agent's web navigation while it works. Hark design lead Abidur Chowdhury told TechCrunch that the visibility is intended to build trust by showing what the agent is doing instead of hiding web actions in the background.
Memory, Action Buttons, and Panels Shape the Experience
Hark Pro's memory layer stores details that can make repeated tasks more useful over time. In its launch post, Hark gave examples such as remembering food preferences, seat preferences, pet interests, or document formatting requirements. The company says users can ask Hark to forget information when they do not want it retained.
The product also introduces Action Buttons, which turn suggested tasks into one-tap actions. Instead of only reminding a user to do something, an Action Button can help complete the task itself, such as paying a bill or canceling an unused subscription.
For longer-running work, Hark Pro includes Projects, dedicated threads with their own files and context. Users can also create Panels: customized mini-apps that pull data from connected services. Hark lists Strava, Spotify, Venmo, Netflix, Rotten Tomatoes, and ParentSquare as examples of services or data sources that can support panel-style experiences.
Pricing, Privacy, and Hardware Plans
Hark Pro is available now for free on web, iOS, and Android. Hark says all features will remain available for free, with paid tiers increasing usage limits. Hark Pro² costs $20 per month for 2x more usage, while Hark Pro³ costs $100 per month for 10x more usage.
Hark's "Secured by Hark" system stores sensitive information such as passwords and credit cards in an encrypted vault that Hark staff cannot see. The company says it will not sell user data, share it with advertisers, or prevent users from deleting their data.
Hark is also building AI-native hardware for 2027.
