Browser Company ends Arc development to focus on AI-powered Dia
The Browser Company has paused Arc’s development to focus on Dia, an AI-powered browsing tool that assists with writing and tasks. Dia is now in alpha and aims for a more cohesive user experience.

The Browser Company Halts Arc Development to Focus on AI-Powered Dia
The Browser Company has officially stopped active development of its web browser, Arc. According to CEO Josh Miller, while security updates and bug fixes will continue, new features are unlikely. The core reason? Arc was "too different" for most users, offering many new concepts but delivering limited immediate benefit. Miller also pointed out that the browser "lacked cohesion" in both its main features and overall value.
Introducing Dia: A New AI-Driven Browsing Experience
Shifting gears, the company is now concentrating on Dia, an AI-powered product first announced late last year. Described as "an entirely new environment — built on top of a web browser," Dia aims to rethink how users interact with the web by integrating AI assistance directly into the browsing experience.
Demos reveal Dia's ability to help users write sentences while pulling factual information from the wider internet. It can automatically insert relevant Amazon links into emails based on simple descriptions and execute complex tasks from user prompts. This builds upon some features the company had explored in Arc’s mobile version, but with a clearer focus on AI-driven productivity.
Current Status and Future Plans
Dia is currently in alpha testing and will soon be available to existing Arc users. Miller emphasized that Dia represents a chance to correct the missteps made with Arc by delivering a more cohesive and rewarding user experience.
The company has considered selling or open-sourcing Arc, but nothing is planned at this time. Open-sourcing poses challenges because Arc is built on an internal SDK that also powers Dia. Making one open source would effectively expose the other, which complicates matters. Still, Miller left the door open for future possibilities.
What Product Developers Can Take Away
- Focus on user adoption: Introducing too many new concepts at once without clear value can hinder user engagement.
- Cohesion matters: Aligning core features with a clear, unified value proposition is essential for product success.
- Leverage AI thoughtfully: Integrating AI to assist with real tasks—like drafting content or retrieving relevant information—can enhance productivity.
- Iterate based on feedback: Dia’s development shows how companies can pivot from earlier products by learning from what didn’t work.
