The AI web browser Dia is drawing inspiration from its predecessor, Arc, an earlier experiment in modernizing the web browsing experience that hailed from the startup known as The Browser Company. On Sunday, The Browser Company founder Josh Miller confirmed that the new AI browser will bring "Arc's greatest hits" to Dia, including things like the sidebar mode, and combine that with AI-native features like memory and agents.
The first browser wars were about speed and simplicity, the next one is about control. Every click, search and purchase is being absorbed into a closed ecosystem where algorithms decide what people see and how it is framed.
