Dia

Dia is the AI-first browser from The Browser Company, the team behind Arc. Instead of bolting a chatbot onto a browser, Dia is built around chatting with what you already have open: ask a question and it can reason across your tabs, summarise pages, compare sources and turn what it finds into a shareable report.

Key facts: Dia launched in beta in June 2025 and became broadly available on macOS in October 2025. Its headline features include chat with tab context, a Morning Brief that surfaces what matters across your day, and reports built from gathered browsing context, plus connections to tools such as Gmail, Google Calendar and Slack. On 22 October 2026 The Browser Company set 22 December 2026 as the shutdown date for Arc and began steering Arc users to Dia, where familiar browser features remain free and AI is optional.

Plans: The browser itself is free. AI features are paid: Better Answers costs $20/month and adds chat with context from tabs and connected tools, while Better Days costs $100/month and adds higher usage plus Morning Brief, reports, decks and meeting recaps; new users also get a 14-day trial of the Better Days plan, according to third-party pricing round-ups. Check the official site before paying, as plan names and limits change.

Best for: knowledge workers — especially on Mac — who live in many tabs and want an assistant that understands their current research rather than a blank chat box. Watch out: Dia is macOS-first, with Windows in early access, and its agent features are deliberately less autonomous than some rivals, so it will not yet book or buy things for you end to end. Who should skip it: users who want a fully autonomous agent that books and buys things end to end.
