Hark Unveils Hark Handoff Browser Agent to Automate Web Tasks

Artificial intelligence startup Hark has introduced Hark Handoff, an automated agent designed to operate inside a web browser and complete online tasks on behalf of users. The system is engineered to navigate websites directly, even when those platforms lack official APIs.

What Happened

Hark, which secured $700 million in Series A funding in May, announced the rollout of Hark Handoff. According to the company, the tool analyses website structures alongside visual information to determine appropriate interface interactions, such as selecting buttons or entering text into forms.

In a demonstration presented by Hark Chief Executive Officer Brett Adcock, the system was tasked with arranging a flower bouquet based on user specifications and flexible prompts like “some of the florist’s choice.” The demonstration footage showed an excerpt of the workflow rather than the full sequence.

Hark stated that the current version operates on a post-trained model, with plans to introduce pre-training later this year. The company noted that this sequence allows it to iterate on its data pipelines, training frameworks, and methods more efficiently. Hark also claims its underlying model focuses on predicting practical next actions—such as specific inputs or on-screen interactions—rather than predicting text tokens like traditional large language models.

Key Highlights

• API-Free Navigation: Hark claims Handoff can perform actions on platforms without official APIs, citing examples such as Walmart, Target, LinkedIn, and OpenTable.
• Broad Task Scope: The agent is designed to execute multi-step activities, including reserving restaurant tables, booking travel tickets, ordering groceries or food, processing returns, and conducting multi-source research.
• Cost and Speed Claims: The startup asserts that its tool operates faster and at lower operational costs compared to other frontier models such as GPT 5.5 and Opus 4.8.
• Upcoming Availability: Hark has introduced a waitlist for the platform, with a wider release targeted for the end of the summer.

Why This Matters

Digital automation agents represent a growing focus across the technology sector. Major tech firms like Google, OpenAI, and Anthropic, alongside early-stage companies such as Aside, Browser Use, Polar, and Strawberry, are developing tools capable of handling complex computer and browser workflows. By designing a system that interacts directly with user interfaces and visual page layouts, Hark aims to enable automation across web services that do not offer developer integrations.

What to Watch Next

Hark plans to begin pre-training its model later this year and intends to launch the Handoff platform publicly by the end of the summer following its current waitlist phase.
