Dia

Dia is an AI-native web browser developed by The Browser Company. It integrates artificial intelligence into every browsing tab and text field. The tool solves context-switching problems by embedding AI assistance directly in the user's workflow.

Features

• Tab-Aware AI Chat: Users can @-mention any open tab to query across multiple pages simultaneously. The system analyzes content from all referenced tabs for comparison and research tasks.
• In-Line Text Editor: Real-time writing assistance appears inside any text box across websites. Users edit drafts without switching to external tools or copy-pasting content.
• Skills Gallery: Pre-built and customizable AI workflows automate repetitive tasks like fact-checking or citation formatting. Users create custom Skills using natural language prompts for one-click execution.
• Local-First Privacy: Browsing data stays encrypted on device by default. The system excludes banking and health sites from AI processing unless explicitly enabled by user.
• Tool Integrations: Native connections to Gmail, Google Calendar, Slack, and Notion enable direct querying. Users search emails or schedule meetings without leaving their current tab.

Use Cases

• For Students: Generate flashcards and quizzes from lecture notes already open in tabs. Highlight confusing paragraphs or video timestamps to request instant explanations without context-switching.
• For Researchers: Compare multiple academic papers or articles side-by-side through AI synthesis. Extract key metrics and citations across sources in a single query operation.
• For Content Creators: Maintain brand voice consistency across client projects using personalized AI writing profiles. Draft social posts or localize content with context from reference materials in adjacent tabs.
• For Enterprise Teams: Deploy with SSO support (Google, Okta, Microsoft Entra ID) and MDM policies. Zero data retention agreements prevent AI partners from training on corporate browsing content.

Dia embeds contextual AI into browser tabs for writing, research, and task automation. Available on macOS 14+ with Apple Silicon; free tier includes core features with usage caps.
