Aug 5, 2026

AI Summary

Hark has introduced its Handoff agent, designed to automate tasks on websites without official APIs. The startup claims its technology can outperform competitors in speed and cost, with plans for wider release by the end of summer.

Hark, a startup that raised $700 million in Series A funding in May, has launched its Handoff agent.
The Handoff agent can navigate websites like Target, Walmart, OpenTable, and LinkedIn to complete various tasks.
It interprets website structures and visual data to determine necessary actions, such as clicking buttons or entering information.
The assistant can perform tasks like ordering food, booking travel, and shopping based on user commands.
CEO Brett Adcock demonstrated the agent's capabilities in a video, showcasing its ability to handle specific and vague requests.
Hark is using a post-trained model for this release, with plans to implement pre-training later in the year to enhance its data processing and training methods.
The company asserts that its model predicts the next action rather than just the next token, differentiating it from large language models.
Hark claims its Handoff agent is faster and more cost-effective than competitors like GPT 5.5 and Opus 4.8.
A waitlist has been opened for the platform, with a planned release by the end of summer.
