Dia
A new AI browser from the makers of Arc. Chat with your tabs. Write with your tabs. Do it all.

Dia transforms your browser into an intelligent workspace where AI helps you think, write, and research—all without leaving your tabs.
From the creators of Arc comes a browsing experience that reimagines how you interact with the web. Instead of juggling multiple tools and apps, Dia integrates AI directly into your workflow, letting you chat with content across your open tabs, draft documents with context from your research, and accomplish tasks faster than traditional browsers like Chrome allow.
Key Features:
- Chat with your tabs: Ask questions about content across multiple open pages simultaneously
- AI-powered writing: Draft and edit text using information pulled directly from your browsing context
- Intelligent workspace: Seamlessly blend research, writing, and browsing in one unified interface
- Built for productivity: Designed to reduce context-switching and keep you focused on what matters
Who It's For: Dia is ideal for researchers, writers, students, and knowledge workers who spend their day synthesizing information from multiple sources. If you're tired of copying and pasting between tabs or losing track of your research, Dia keeps everything connected and accessible.
Built by the team that redefined browsing once before, Dia makes working on the web feel effortless.
