Hark AI and the Hark Pro App Explained

How Brett Adcock's free assistant app works and what Hark says about your data.

Reviewed by Jonathan West · Updated Oct 10, 2026

Hark AI usually means Hark Pro, a free assistant app from the AI lab Hark. It launched on October 6, 2026, and proposes tasks before you ask for them. It connects to services such as Google and Outlook and works through websites for you. Rather than functioning as a conventional conversational chatbot, Hark Pro operates as a full-screen interface designed to control web browsers on behalf of the user.

Available across web browsers, the Apple App Store, and Google Play, Hark Pro pairs daily productivity tools with a cloud-based Computer Use Agent (CUA) called Handoff. Founder Brett Adcock launched the product following a Series A funding round of over $700 million at a $6 billion post-money valuation in May 2026. Hark's privacy policy says it does not use your inputs, outputs, memory or connected account data to train AI.

Hark Pro can sign in to websites with passwords and cards stored in its Secured by Hark vault, and it acts inside any account you connect. Every feature is free. Paid plans at $20 and $100 a month add usage, but Hark does not publish the limits.


What Hark Pro Is

Hark Pro is a proactive personal assistant application that operates web browsers and manages schedules, messaging, and account actions across desktop and mobile devices. Hark (not the old English verb meaning "listen") is an AI lab in San Jose, California, according to Intel Capital. It is a separate company from Figure AI, the humanoid-robot maker Brett Adcock also runs as CEO.

Hark posted its launch announcement on October 6, 2026. Its launch video calls Hark Pro "an operating system for your life." In reporting by TechCrunch, Hark defined its core objective as creating a functional user interface for artificial intelligence computers rather than pursuing Artificial General Intelligence (AGI). Hark Pro presents a full-screen workspace that combines concise messaging replies, multimedia widgets, and background browser automation.

  • Company: Hark, an AI lab based in San Jose, California.
  • Founder: Brett Adcock, founder and Chief Executive Officer (CEO).
  • Launch Date: October 6, 2026.
  • Pricing: Free baseline tier, with Pro² at $20 per month and Pro³ at $100 per month.
  • Platforms: Web browsers, Apple iOS, and Google Android.

Hark AI System Overview and Daily Workflow

Daily interaction within Hark Pro centers on a single conversational stream with persistent memory, project workspaces, and customizable dashboard panels. The primary chat view retains information across conversations, maintaining an ongoing memory profile that the user can inspect or ask Hark Pro to forget at any point. For structured objectives like job searches or vacation planning, the Projects feature creates isolated workspaces that store documents and relevant discussion threads.

Home is a customizable space for timely information. The app's background is a live atmospheric simulation that Hark says draws on "over a dozen real-time signals." TechCrunch describes it as imagery matched to local weather and time. Custom interactive panels operate as micro-applications built from natural language descriptions, pulling live data feeds from connected services such as Spotify, Strava, Netflix, ParentSquare, and Venmo. Action Buttons let you act on a notification with one tap, such as paying a bill. Hark then carries the task out "start to finish."

According to CryptoBriefing, Hark Pro is engineered to execute errands before the user thinks to request them. In a demo for TechCrunch, Hark Pro flagged expenses to approve, emails to answer and a flight to book. It also renewed a colleague's car registration on the California DMV website. Outside the browser, Hark connects to Google and Microsoft Outlook through APIs. It can also read files, query external databases and use the open-source Model Context Protocol (MCP).


Handoff Computer Use Agent in Hark AI

Hark Handoff functions as an autonomous cloud agent that executes digital tasks by controlling virtual computer screens without relying on developer APIs. Originally introduced in an August 2026 research preview, Handoff provisions a dedicated virtual machine equipped with an independent browser, file directory, and command-line terminal for each assignment. The underlying model generates sequences of keyboard inputs and cursor movements targeting exact screen coordinates to click, scroll, and type.

Hark's case for this design, as eWeek reported it, rests on two figures. Hark estimates fewer than one in 1,000 websites offer public APIs. Across nearly 3 million minutes of user screen time, it found 74.9 percent was spent in browsers. According to Hark's launch post, Handoff can run up to six browsers simultaneously and interact with millions of web domains. Some third-party accounts, including CryptoBriefing, reported that Handoff can manage up to 36 browsers, but Hark's official documentation explicitly specifies six browsers.

Handoff was built on NVIDIA AI infrastructure. As of Hark's August post, training had started with supervised fine-tuning (SFT) and reinforcement learning (RL). Mid-training was under way, and pre-training was planned for later in 2026. On the Online-Mind2Web human-evaluation benchmark, Hark reported an evaluation score of 97.7 for Handoff, compared to 92.8 for OpenAI's GPT-5.4 and 84.1 for Anthropic's Claude Opus 4.8. In reporting by eWeek, Hark cited operational token costs of $0.18 per million input tokens and $2.37 per million output tokens, though eWeek noted this calculation excludes retries and infrastructure costs. eWeek also reported that the results have not been independently reproduced, and that WebTailBench and Hark's internal evals ran on Hark's own harness. Hark's launch post still calls Handoff "independently verified," so that label is Hark's claim.


Pricing Tiers and Usage Allocations

Hark Pro structures its commercial model around usage capacity rather than feature paywalls, offering an identical functional toolset across free and paid subscriptions. According to the official pricing page, the baseline plan is free to use, displays no advertising, and includes all system capabilities. However, Hark does not publish an exact numerical usage ceiling or token quota for free accounts.

Users who require higher automation volume can select paid subscription tiers. The Pro² subscription costs $20 per month and provides twice the operational volume of the standard tier, illustrated on the pricing page as enabling 40 grocery delivery orders. The Pro³ tier costs $100 per month and offers ten times the standard volume, with Hark citing examples like coordinating 50 weddings or purchasing 100 grand pianos. As of October 2026, the pricing page lists no annual plans.

  • Free Plan: $0 per month, ad-free interface, complete feature access, unstated usage ceiling.
  • Pro² Plan: $20 per month, two times higher execution volume.
  • Pro³ Plan: $100 per month, ten times higher execution volume for heavy users.
  • Feature Parity: Every plan includes identical tools; subscriptions expand execution capacity alone.

Privacy and Account Security

Security in Hark Pro relies on credential tokenization, isolated credential storage, and explicit contractual bans on model training with consumer data. Hark's launch post describes "Secured by Hark," an in-house encrypted vault for credit cards and passwords. Hark says it cannot see inside the vault or see passwords as you type them. Credentials remain encrypted from the vault directly to destination forms.

While the agent browses, Hark Pro shows its actions in a small live window. Design lead Abidur Chowdhury told TechCrunch the window is meant to build trust. Hark's security page adds: "There's always a button to cancel your order." Under the privacy policy updated on October 1, 2026, Hark states that customer inputs, outputs, memory records, connected accounts, and sandbox data are never used to train machine learning models.

Accounts do not require manual opt-out requests to prevent model training. When outside AI providers handle your data, Hark's privacy policy says a written agreement bars them from training on it. The security page separately says models from vetted third parties have "0 data retention." Data used to run the service is kept for the lifetime of your account, and the policy also lists research as a use. Users can view, edit, or purge their memory profile at any time by issuing an agent command. Hark states that it does not direct its services towards children under 18 years of age. Hark does not publish independent compliance certifications such as System and Organization Controls 2 (SOC 2) or International Organization for Standardization (ISO) audits on its security page as of October 2026.


The Company Behind Hark Pro

Hark operates as an independent, private artificial intelligence laboratory founded in late 2025 by serial entrepreneur Brett Adcock. The Next Web reports that Adcock committed $100 million of his own money to Hark. His earlier companies, per Wikipedia, include Vettery and Archer Aviation, which he co-founded, plus Figure AI and Cover. Gizmodo reported in March 2026 that Abidur Chowdhury, a former Apple designer who helped lead iPhone Air design, had joined Hark. TechCrunch says he now leads design there. Hark had around 70 people at the time of its May 2026 Series A.

In May 2026, Hark announced a Series A funding round of over $700 million at a $6 billion post-money valuation, led by Parkway Venture Capital. Backers listed in Hark's Series A announcement and repeated by Intel Capital included NVIDIA, Align Ventures, AMD Ventures, ARK Invest, Brookfield, Greycroft, Intel Capital, Prime Movers Lab, Qualcomm Ventures, Salesforce Ventures, and Tamarack Global. In August 2026, Hark announced a partnership with AT&T, which is also investing in Hark. The two are working on device certification and network connectivity for hardware that works without a phone or Wi-Fi. That same month, Hark entered a multi-year partnership with NVIDIA to secure compute infrastructure on the Vera Rubin hardware architecture.

Hark's manifesto promises "a series of bespoke native hardware devices and agentic computers." In March 2026, eWeek reported Adcock saying Hark is "working on a family of AI devices both for yourself and for the home." TechCrunch says Hark promises an AI-native device in 2027. Chowdhury cited the "creep factor" of wearable cameras, but the form factor, price and launch market are undisclosed as of October 2026.


Workplace Considerations for Enterprise Accounts

Deploying Hark Pro across corporate email and financial systems introduces governance challenges involving direct credential handling, browser control, and unverified compliance standards. TechCrunch lists Dots among Hark Pro's competitors. Hark Pro signs in to websites with stored logins and acts there for you. If the agent misreads a page, it can take the wrong action inside an account it is signed in to.

TechCrunch raised an open question regarding whether fine-tuning models specifically for procedural browser operation limits their broader reasoning capacity compared to general frontier Large Language Models (LLMs). The security page points to a separate trust center at trust.hark.com, which returned no readable content as of October 10, 2026.

This assessment of Hark Pro would change if Hark publishes independent compliance reports, or if independent benchmark audits confirm Handoff's performance claims. Users evaluating Hark AI can test personal errands on the free tier of Hark Pro while keeping enterprise accounts disconnected until Hark publishes independent compliance certifications.

Hark Pro actively navigates websites using stored credentials. Avoid connecting enterprise accounts until your organization has read the AI-provider terms in Hark's privacy policy and Hark has published independent compliance audits.
