What sites can Hark Handoff actually use?

Hark says Handoff navigates real consumer sites without official APIs, including Target, Walmart, OpenTable, and LinkedIn, by watching the page and predicting the next interaction. Each session runs in a dedicated virtual computer, so the agent has its own browser state instead of hijacking the user's.

Can I try Hark Handoff today?

Hark Handoff is a research preview as of 5 August 2026 — access is gated by a waitlist at hark.com and the company says wider availability will land 'later this summer'. No public pricing or free tier has been announced yet.

Is Hark a real company or a stealth startup?

Hark is a well-funded AI startup that closed a $700M Series A in May 2026 and now says it is 'building the most advanced personal intelligence in the world'. Handoff is its first shipped agent product, ahead of a broader personal-intelligence platform teased on hark.com.

Hark Handoff — browser-use agent predicts the next click, not the next token

Q: How is Hark Handoff different from ChatGPT's Operator or Claude computer use?

Hark Handoff is trained to predict the next action — a click at a coordinate or a keystroke into a field — rather than the next token, which is the standard objective for GPT-5.4 or Opus 4.8. Hark says that shift is what lets Handoff drive real sites at less than one-tenth the token cost of those general-purpose models.

Hark opened a research preview of Handoff, a browser-use agent that runs in a dedicated virtual computer and drives sites without APIs — Target, Walmart, OpenTable, LinkedIn. Hark says it tops the OM2W benchmark and costs less than a tenth of the token price of GPT-5.4 or Opus 4.8.

Introducing Hark Handoff — a browser-use agent that predicts the next click

Hark's first agent runs in its own virtual computer and is trained to predict the next click instead of the next token.

Benchmark claim	Top score on OM2W (per Hark)

What is it?

Hark Handoff is a browser-use agent that Hark opened in research preview on August 5, 2026. Each session gets its own virtual computer, and the agent drives real sites — Target, Walmart, OpenTable, LinkedIn — through the pixels and DOM instead of a public API.

How does it work?

The model is trained to predict the next action a user would take on a page — a mouse click at a coordinate, a keystroke into a field — rather than the next token in a stream, which is the standard objective for GPT-5.4 or Opus 4.8. Hark says that action-first objective is why Handoff can navigate sites it has never seen before with less scaffolding.

Why does it matter?

Hark claims Handoff tops the OM2W browser-agent benchmark and runs at less than a tenth of the per-token price of GPT-5.4 and Opus 4.8, backed by a $700M Series A from May 2026. If those numbers hold, computer-use agents move from experimental Operator/Computer-Use demos toward a price point where teams can put an autonomous browser in front of real workflows.
