About
Dia is the AI-first browser from The Browser Company, the team behind Arc, which was acquired by Atlassian in 2025. Instead of bolting a chatbot onto a sidebar, Dia treats your open tabs as context: ask a question and it answers using the pages you are actually reading, drafts writing in your own tone, and carries skills you can build for repeated tasks like trip planning or code review.
After a long invite-only beta, Dia launched publicly in October 2025 and is free to use as a browser, with paid plans for its AI: Better Answers at $20 a month and Better Days at $100 a month. It requires macOS 14 or later on Apple Silicon. Tracker blocking, ad blocking and encrypted sync are built in, and the whole thing feels unmistakably native to the Mac.
Alternatives
- Zen Browser
Pick Zen if you want a free, open source browser based on Firefox: and runs on Intel and Apple silicon Macs as well as Windows and Linux.
- Safari
Stay with Safari if you want a browser already on your Mac with tracking protection built in and nothing to pay for, and do not need AI chat across your tabs.

Curator's Note
“The only AI browser where the intelligence feels like part of the furniture rather than a gimmick stapled on.”
