Dia

Dia is an AI browser from The Browser Company, the team behind Arc. It is built for knowledge workers who live in their tabs, answering questions using the context of your open pages, Slack, and Google Workspace. Instead of switching tools to find an answer, you ask Dia once and it digs through your work like someone who has read every thread.

Key Highlights

• Morning Brief that lays out your calendar, inbox, and key links before the day starts
• Proactive Suggestions that follow your work and surface what to do next
• In-tab AI chat that answers using context from your tabs, Slack, and GSuite
• Skills: saved shortcuts for repeatable workflows
• Profiles, Splits, and named tab groups to separate work and personal browsing
• Privacy controls for memory, trackers, and ads, with end-to-end encrypted Sync

What Makes It Different

Dia reads across your tabs rather than treating each page in isolation. It gathers what is scattered across Slack, Notion, and Calendar into a shareable report, or pulls the right GitHub PR and Notion spec into your tab bar so one click lands you in the correct place. It also opens each meeting with its agenda, notes, and related docs plus a countdown, so you arrive on time.

Features & Capabilities

You can ask Dia to answer a question, draft an output, or assemble a report, drawing on your connected context instead of a blank chat. Skills save repeatable workflows as one-click shortcuts, created just by asking the chatbot. Two ship by default: Write drafts text in your voice, and Code helps with programming based on your preferences.

Profiles give you distinct tabs, logins, and color themes for work versus personal browsing, while Splits remember your layout for recurring 1:1s. Tab groups get readable names like "Q2 Planning," and Dia for Work adds SSO and admin tools for teams.

User Ratings and Testimonials

As a newer product, Dia does not yet have broad aggregate ratings on G2 or similar sites. Early reviewers praise the in-tab AI and the Morning Brief for cutting context switching, and note the lineage from Arc (The Browser Company was acquired by Atlassian for $610 million in 2025). Common criticisms are that the free tier limits AI features, that Dia remains macOS-only, and that the $20 Pro price is steep for a browser.

Pricing & Value

• Free: $0, full browsing with AI chat available a limited number of times each day
• Pro: $20/month, unlimited AI chat and Skills, personalized memory, and a 14-day free trial
• Dia for Work: custom team plan that adds SSO and admin controls

The free tier is enough to try the browser and its AI, while Pro removes the usage limits for daily use. The Browser Company has said more tiers (from about $5/month up to higher business plans) are planned.
