Hark unveils Handoff, a browser use agent for everyday web tasks

Founded by Brett Adcock earlier this year, Hark's Handoff targets tasks like ordering food on DoorDash, booking flights, and shopping. Adcock claims Handoff was independently verified as the best internet-use model, beating ChatGPT 5.4 and Opus 4.8, while Hark says it is faster and cheaper than rivals.
