Hark Unveils Handoff, a Browser AI Agent That Can Shop, Book Travel, and Complete Online Tasks

Hark has introduced Hark Handoff, a browser-based AI agent designed to complete tasks across websites, including services that do not provide official APIs. The company said the agent can navigate platforms such as Target, Walmart, OpenTable and LinkedIn by interpreting website layouts and visual elements to determine when to click buttons or enter information.

Hark Handoff is intended to automate a range of online activities from a single prompt. According to the company, the agent can place food and coffee orders, book travel, file returns, shop for everyday items, reserve restaurant tables and conduct research by gathering information from multiple online sources.

In a demonstration, Hark CEO Brett Adcock showed the agent assembling a flower bouquet based on user preferences, including handling open-ended requests such as "some of the florist's choice." The demo displayed only part of the workflow, making it difficult to evaluate the agent's full performance.

For the initial release, Hark said Handoff is powered by a post-trained model, with plans to move to a pre-trained version later this year. The company said this approach allows it to improve its data pipeline, training infrastructure and model development process more quickly before expanding the system's capabilities.

Hark also said its model is designed to predict the next action instead of the next token. According to the company, those actions can include interactions such as clicking on-screen elements or entering text into specific fields, enabling the agent to perform tasks directly within a web browser.

The launch comes as browser automation has become an increasingly competitive area of AI development, with companies including Google, OpenAI and Anthropic pursuing computer-use agents alongside startups focused on browser-based task automation.

Hark said Handoff delivers faster performance than competing browser agents while costing less than models including GPT-5.5 and Opus 4.8. The company has opened a waitlist for the platform and said it plans to make Hark Handoff available by the end of the summer.
