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, Agents, Consumer, and The Browser Company.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/dia-browser: open an issue to ask a question, or submit a pull request to add artifacts.
