Dia
AI browser for work that answers questions across tabs and tools
What is Dia?
Dia is an AI browser for macOS from The Browser Company of New York, the makers of Arc. Its free plan is a browser with profiles, tab groups, split view and a built-in ad and tracking blocker but no AI features. Paid plans add a chat assistant that draws on open tabs and connected tools such as Slack, Notion and Google Calendar, a daily Morning Brief, and generated reports and slide decks.
Dia has a free plan. Paid plans start at $20 per month (Better Answers). See every plan
Good for
- Mac users whose work is spread across Slack, Notion, Google Workspace and Teams
- People who want a daily brief and meeting prep prepared for them
- Arc users moving to the company's newer browser
Worth knowing
- The free Better Browser plan has no AI features; chat needs Better Answers at $20 per month, and the Morning Brief and reports need Better Days at $100.
- Paid usage is metered in Tasks. When the monthly allowance runs out, AI features pause unless extra usage is bought in $20 credit blocks.
- Dia is available for macOS only; the site lists Windows as coming soon.
- Paid plans began rolling out to new Mac users on August 17. Existing users keep free access until they get at least 30 days' notice.
Key features
- Chat with context from tabs and tools
- On paid plans, a question asked on any page is answered using open tabs and connected tools such as Slack, Notion, Google Workspace and Microsoft Teams.
- Morning Brief
- A daily brief lays out the calendar, inbox and key links before the workday starts. It is part of the Better Days plan.
- Reports, decks and recaps
- Dia gathers context scattered across tools into a shareable report or a slide deck with headers and layout. These are part of the Better Days plan.
- Meeting prep
- Before a call, Dia opens the meeting page, agenda, notes and related documents and shows a countdown to the start time.
- Profiles, tab groups and split view
- Profiles keep work, freelance and personal tabs, logins and AI separate. Related tabs are grouped under descriptive names, and split view layouts are remembered.
- Privacy controls
- Ad and tracker blocking are built in, memory and chat personalization can be switched off, and synced data is end-to-end encrypted. Dia for Work adds SSO and admin tools.
