Key features
Free tier available, Dia Pro at $20/mo
People who spend their day in a browser and want AI help without switching to a separate app like ChatGPT or Claude
AI is the foundation of the browser, not a bolted on feature. Every interaction is designed around AI assistance from the ground up.
What it does
AI Chat with Tabs
Chat with any open tab to ask questions, get summaries, extract information, or discuss what you are reading. The AI sees the page content and can respond in context.
Learn moreSkills (Built in and Custom)
Teach Dia repeatable tasks like summarizing articles, translating pages, or formatting notes. Built in Skills handle common tasks; custom Skills let you define your own workflows.
Learn moreMemory
Dia learns your preferences, writing style, and habits over time. It remembers what you like without you having to configure anything explicitly.
Learn moreAI URL Bar
The address bar doubles as an AI input. Ask questions, describe what you are looking for, or give instructions, and Dia responds with answers or takes action.
Learn moreWriting Assistance
Get AI help with writing anywhere in the browser. Compose emails, draft messages, rewrite text, or adjust tone without switching to a separate AI tool.
Learn moreSmart Tab Management
AI powered tab organization that groups related tabs, suggests which tabs to close, and lets you search across all open tabs by content.
Learn morePage Summarization
Summarize any webpage with one click. Useful for quickly triaging long articles, documentation, research papers, and news stories.
Browsing History Intelligence
Dia uses your browsing history to provide more relevant answers and suggestions. Ask about something you read last week, and it can help you find it.
Profile Switcher
Added in v1.22.0, the profile switcher lets you manage multiple browsing profiles (for example, work and personal) with separate bookmarks, history, and preferences. Switch between profiles seamlessly without logging in and out.
Arc's Best Features
Dia inherits Arc's best design ideas: clean interface, keyboard shortcuts, split view, and a focus on reducing clutter. Built on Chromium, so Chrome extensions work. With Arc officially shutting down, Dia is the direct successor carrying forward Arc's design philosophy.

Cons
