The Browser Company will shut down its Arc web browser on December 22, according to TechCrunch and Engadget.

The company is pushing users to switch to Dia, its browser built around AI, the outlets reported. It announced the decision Thursday, TechCrunch said.

"Keeping a browser secure takes constant, dedicated work that is only increasing in the age of AI," the company wrote, according to TechCrunch.

The company said Dia was built to meet today's security standards, TechCrunch reported. That is where its engineers will focus, it said.

The shutdown comes in three steps, TechCrunch reported. As of Thursday, no one can make a new Arc account, it said. On November 23, the Arc Search phone app will lose its AI features and syncing, TechCrunch reported. It will still work as a basic browser.

On December 22, Arc will stop working on Mac and Windows, TechCrunch and Engadget reported. Users will no longer be able to get into their accounts, the outlets said. TechCrunch said personal data will be deleted within 30 days.

Bookmarks, passwords, extensions and history will move over to Dia, TechCrunch and Engadget reported. The AI features in Dia are optional, the outlets said.

Dia will keep some Arc features, TechCrunch reported. Arc's well-known side tabs will remain as an option, it said.

Many users on social media were let down and asked the company to make Arc's code public, TechCrunch reported. But CEO Josh Miller has said that would mean giving away the core of Dia, TechCrunch said.

Arc had loyal fans, but it never caught on widely, TechCrunch and Engadget reported. The company stopped adding new features to Arc in 2025, TechCrunch said. Atlassian bought The Browser Company for $610 million that year, it reported.

What we know: Arc will stop working on December 22, and users can move their data to Dia.
What we don't: How many Arc users will switch to Dia.
