Arc

Arc reimagines the browser as an AI-powered workspace with spaces, split views, and built-in features that summarize, organize, and automate your tabs.

Overview

Arc by The Browser Company replaced the tab strip with a sidebar of spaces and pinned favorites, then pushed further with AI features collectively branded Arc Max. The browser can generate instant page summaries, tidy tab titles, and pull answers from open tabs through a command bar that behaves like a search-aware assistant. Its Little Arc window handles quick lookups without breaking flow, while boosts let users customize any site’s appearance and behavior with simple instructions. Deep organization features — split view, folders, and automatic tab archiving — make heavy research sessions manageable, and the mobile companion mirrors the same spatial logic on phones. The team has since applied everything learned to its next-generation AI browser, Dia, making Arc both a polished daily driver and a proving ground for agentic browsing ideas. Under the hood, Arc syncs spaces and boosts across devices with end-to-end encryption, and its team ships unusually frequent updates informed by a large community of power users who treat the browser as a craft rather than a commodity.

Who Is It For

Knowledge workers drowning in tabs who want a browser that structures research for them, and early adopters who like testing AI browsing features before they become standard everywhere. It also suits students and researchers juggling multiple projects who want each project’s tabs to live in their own persistent space.
