Dia

Dia is an AI-first browser from The Browser Company that provides context-aware assistance across your open tabs, acting as an in-line writing partner, tutor, planner and shopping concierge. Beyond built-in AI features, Dia introduces Skills—community-created shortcuts for repeatable workflows that you can discover, remix, and create yourself. Skills cover categories from research and development to writing, planning, and shopping, with a growing library of one-click automations like fact-checking, transcript generation, content analysis, and more. The browser emphasizes user control over privacy and is currently available on macOS 14+ with Apple Silicon.

Core AI Features:

• In-line copy editor — edit and improve text directly inside form fields and text boxes without copy-paste.
• Chat with your tabs — ask questions that use content from open tabs to give context-aware answers and comparisons.
• Tutor in every tab — get step-by-step explanations, practice problems and breakdowns of complex concepts while you browse.
• YouTube timestamps & instant summaries — jump to relevant moments and read concise summaries of videos and long articles.
• Planning assistant — generate immediate to-do lists, meeting takeaways and formatted outputs based on page content.
