# Dia

> An AI-powered browser that embeds in-line writing, research, tutoring, planning and shopping assistance directly into web tabs, currently available for macOS 14+ on Apple Silicon.

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.*

**Skills (Workflow Automation):**

- **One-click automations** — *invoke Skills like `/fact-check` for instant verification, `/transcript` for YouTube video transcripts, `/best-word` for context-aware word suggestions, `/outline` for essay structures, and hundreds more.*
- **Custom Skills** — *create your own Skills to automate repetitive browsing tasks, then share them with the community or keep them private.*
