Dia
AI-first browser from the makers of Arc, built for SaaS-heavy knowledge work.
What is Dia?
Dia is The Browser Company's AI-first browser and the successor to Arc, weaving an AI assistant into browsing for SaaS-heavy knowledge work. Arc is now in maintenance mode after Atlassian's 2025 acquisition.
