Dia Browser

Dia Browser is an AI tool that works as an AI browser for work, built by The Browser Company of New York, the team behind Arc, for professionals who spend the day across tabs, meetings and tools such as Slack, Notion, Teams and GitHub.

What can the Dia AI browser do?

Dia “reads between the tabs”: ask once and it digs through your context (open tabs, Google Workspace, Teams and other connected tools) to find, summarize, draft or build what you need. Each morning the Morning Brief lays out your calendar, inbox and key links, and synthesis turns scattered information into a report worth sharing. Ask for a deck and it produces slides with headers, layout and flow.

Which work features does Dia add to the browser?

• Profiles that separate work, freelance and personal life with their own tabs, logins and AI.
• Live Work, which surfaces active PRs, specs and drafts in the tab bar.
• Better Meetings with agenda, notes and docs open before each call.
• Splits and auto-named tab groups.

Is Dia Browser private and secure?

It is built on Chromium with Google services disabled (no GAIA account integration, no UMA metrics), blocks ads and trackers, end-to-end encrypts Sync and never sells your data. Dia for Work adds SSO and admin tools.

Dia Browser pros and cons

Pros: the AI lives in the browser itself and uses your real context without copy-pasting. Cons: it is only on macOS and Windows, AI features require a paid tier with usage limits measured in Tasks, and the interface is English-only.
