The Arc gap
Why power users are searching for Arc alternatives
Platform lock-in
Arc is best known as a Mac-first experience. If you need a consistent workflow on Windows, the options are limited or inconsistent.
AI that only chats
Arc Max summarizes and answers questions, but it cannot fill forms, book flights, or run research across multiple sites on its own.
An uncertain future
With Arc shifting focus and new browsers like Dia and Zen emerging, users want a stable, cross-platform browser built for the AI era.
