Dia (The Browser Company)

Dia is The Browser Company's successor browser to Arc, positioned as an AI-native browser that integrates a chat assistant, contextual search across open tabs and connected apps (GSuite, Slack, Notion, GitHub), Morning Brief summaries, automatic Reports, Better Meetings, and Live Work integrations directly into the browsing surface. Currently available on macOS 14+ on Apple Silicon. No public developer REST API or SDK has been published; the product is consumer-facing and integrates with third parties as a user-side agent rather than via developer APIs.

Dia (The Browser Company) publishes 3 APIs on the APIs.io network. Tagged areas include Browser, AI Browser, Agent, Consumer, and The Browser Company.
