Editor's Verdict
Editor's VerdictDia Browser is miles ahead when it comes to modern browser features and design. It carries over everything that made Arc stand out, like its refined sidebar and top-tier tab management, and layers in an AI chat experience that actually works well. The team behind it is focused on pushing browser design forward, with resources to keep innovating.
Sidekick, on the other hand, feels dated. Its so-called productivity features are now basic and found everywhere, and the overall experience doesn't hold up against newer browsers like Dia. The design is behind, and it's no longer even actively developed since the team got pulled into building something else.
If you want a browser that feels current and actually helps you work better, Dia is the clear pick. Sidekick just doesn't keep up.
