Dia Browser is an AI web browser from The Browser Company, the makers of Arc, now part of Atlassian. Its address bar doubles as an AI assistant that can read your open tabs, summarise pages, write drafts and run reusable Skills. Dia is free to download, and Dia Pro costs $20 a month for more AI usage.
What is Dia Browser?
Dia is designed to put AI right inside your browser. Instead of copying text into a chatbot, you can ask Dia about the page you are on or compare several open tabs, and it answers in a side chat.
It supports Skills, which are saved prompts for repeat tasks like writing, research or code review, and it can connect to work apps like Slack, Notion, Google Calendar and Gmail. Atlassian acquired The Browser Company in 2025.
