Dia browser has launched version 2.5, integrating several key features inspired by The Browser Company’s Arc, specifically targeting Mac and iOS users. The update, released on November 3, 2025, introduces Arc-like functionalities such as customizable tab 'Spaces' and visual note-taking 'Easels' into Dia's existing AI-driven web experience.

Dia Labs CEO Elena Vasquez stated this move evolves agentic AI for creative workflows, positioning Dia as an AI-first browser. Available free on the App Store, the update positions Dia, which claims over 500,000 active users, as a formidable competitor in the burgeoning agentic AI browser market, offering premium AI agents via subscription at $9.99/month or $99/year. This aims to blend Arc's intuitive user experience with Dia's advanced AI automation.
