Arc → Dia

The Browser Company, the maker of Arc, announced on October 22, 2026 that Arc is sunsetting on December 22, 2026. Arc’s own notice says new accounts can no longer be created and points users to Dia, the company’s other browser. This page covers what stops and when, what Dia costs, and what the importer carries over.

What stops, and when

Arc’s notice lists three dates. On November 23, 2026, the AI features in Arc Search on iOS and Android, including Browse for Me, are switched off, and sign-in and tab sync end on mobile. Arc Search still works as a basic browser after that. On December 22, 2026, Arc stops working on macOS and Windows, and Arc Search leaves the Google Play Store. Accounts are deactivated on that day, and personal data tied to them is deleted within 30 days. CyberInsider reports a further deadline of December 15, 2026 for asking for a copy of account data or its deletion; the Arc page read for this guide does not list it, so confirm it in the Arc Help Center.

What Dia is and what it costs

Dia describes itself as a browser for work, available for macOS and Windows. Its site lists profiles that keep work, freelance and personal tabs and logins apart, tab groups, split views, and sync that it describes as end-to-end encrypted. The pricing page sets out three tiers. Better Browser is free and includes profiles, tab groups, split view, picture-in-picture video, an ad and tracking blocker and cross-device sync, with no AI features. Better Answers adds asking about any page and chat that draws on connected tools such as Slack, Gmail and Notion. The pricing section of that page shows $10 per month for it, while the FAQ shows $20 per month, so the current figure is worth confirming before subscribing. Better Days costs $100 per month and adds a daily Morning Brief, reports and meeting preparation. Extra usage is sold in $20 blocks, and new users get 14 days of Better Days without a credit card. The page also says existing users keep their current free access and will get at least 30 days of email notice before paid plans apply to them.

The trade-off is the focus. Dia is built around AI, and its paid plans are priced around those features. CyberInsider reports that AI requests can send relevant page content to outside model providers and that sharing content to improve Dia is on by default but can be turned off in settings. Someone who only wants a tidy browser can stay on the free tier, which has no AI features.

How the move works

On macOS, Arc’s notice says to open Dia and choose Import from Another Browser; on Windows, open the Dia app menu and choose Import from another browser. The notice says the importer can bring over passwords, history, tabs, Profiles, folders, bookmarks and extensions. CyberInsider adds detail: Arc Spaces become Dia Profiles, folders become pinned Tab Groups, and nested folders turn into separate groups. It lists what does not transfer, namely Easels, Boosts, other Arc-only features, saved payment methods and autofill data, and advises keeping Arc installed until the import finishes.

For a manual copy, Arc has an export option. On macOS it is under Arc, Settings, Advanced, Export Data. On Windows it is under Settings, Advanced, Export Spaces and tabs.

Before December 22

• Export Arc data from Settings, Advanced, as a backup.
• Install Dia and run the importer while Arc is still installed.
• Check that Spaces landed as the Profiles expected and that folders look right.
• Re-enter payment methods and autofill data by hand.
• Decide whether the free tier is enough before looking at paid plans.
• Review the AI and data-sharing settings.

Other browsers can also take Arc data through the export, including open-source options, and they are covered separately.
