An AI-native desktop web browser from The Browser Company, the team behind Arc. Dia bakes a chat assistant and reusable 'skills' directly into the address bar, with awareness of your open tabs and browsing history, so you never need to copy context into a separate chatbot. It launched publicly on macOS in 2025. A free tier covers light AI use; a $20/month Pro plan removes the AI usage limits.
