Reviewers mostly see Arc as a genuinely different browser that improves day-to-day work through spaces, vertical tabs, split view, strong shortcuts, and a polished interface that helps tame tab overload across work and personal contexts. Many say it replaced Chrome or Safari for them, though several note a learning curve. The main complaints are practical: weak or awkward bookmark behavior for some users, high CPU or battery use, occasional bugs and site compatibility issues, uneven Windows support, and uncertainty about Arc’s future pace of development."
