Overview
Dia is the browser The Browser Company built after Arc, and its positioning is narrow on purpose: not a general browser for everyone, but one for the eight hours you spend working. Its own homepage puts it as more than a browser, a better workday, and the pitch rests on reading the tabs you have open plus the context inside Slack, Notion, Gmail and GitHub.
Morning Brief is the hook. Open the browser and it assembles today's calendar, the inbox items that need you and a few key links into one page, so the day starts without visiting five tools to find out what is happening. It is designed as a repeatable daily action rather than a one-off question.
Everything else reduces window switching. Profiles keep work, freelance and personal life as three separate sets of tabs, logins and AI memory, one swipe apart. Live Work pulls what is moving in GitHub and Notion into the tab bar so a click lands on the right pull request or spec. Splits remembers the side-by-side layout you use for meetings, and Decks turns scattered context into slides you can present without redesigning. Privacy toggles sit in plain sight, with memory, ads and data sharing each switchable, and sync is end-to-end encrypted.
Key Features
- Morning Brief: At the start of the day it assembles your calendar, the inbox items that need attention and a few key links into a single page, replacing the routine of opening five tools first.
- Cross-tool answers: One question can read across GSuite, Teams, Slack, Notion, GitHub and Figma and return an answer that spans sources instead of summarising the current page.
- Profiles for separate identities: Work, freelance and personal each get their own tabs, login state and AI memory, switched with a swipe so contexts never bleed into each other.
- Live Work and Splits: Open pull requests and documents hang in the tab bar for one-click access, and your split layout is remembered so a recurring meeting restores in one tap.
- Decks as output: Scattered documents and conversations become a structured deck with headers, layout and flow, ready to present without being rebuilt in presentation software.
- Privacy controls in view: Memory, personalised new chats, ads and content sharing are four visible switches you can turn off, sync is end-to-end encrypted, and data is not used for ad profiles.
Use Cases
- Starting the day from Morning Brief and clearing calendar clashes and pending replies in one pass.
- Splitting a job and a side project across two Profiles so logins and memory stay apart.
- Setting up Splits before a recurring meeting and restoring the layout in a single click next time.
- Turning material scattered across tools into a shareable deck when a report is due.
- Asking Dia to gather earlier discussions from Slack and Notion instead of scrolling through history.
- Teams standardising on Dia for Work for SSO and admin controls while keeping personal profiles separate.
Pros
- Morning Brief collapses the start of the day into one page, which makes the habit repeatable.
- It reads several work tools at once, answering with context rather than a page summary.
- Profiles keep work and personal identity apart, including memory and logins.
- Live Work, Splits and Decks all point at the same goal of fewer window switches.
- Privacy switches are visible by default, sync is end-to-end encrypted and data is not used for ad profiles.
- The free tier is usable on its own, and two paid steps keep the upgrade path clear.
Pricing
Better Browser is free and includes Profiles and tab groups, split view and picture-in-picture, built-in ad and tracker blocking, and cross-device sync on macOS and Windows. Better Answers is 10 dollars a month and adds the Morning Brief, cross-tool asking with read and write, and connections to Slack, Gmail, Notion, Outlook, GitHub, Google Calendar and Figma. Better Days is 100 dollars a month with twenty times the asks for all-day use. Dia for Work adds SSO and admin tooling for teams and requires contacting sales. Every tier carries a monthly usage allowance.
Summary
Dia starts from an observation about the working day: the difficulty is rarely finding an answer, it is that the answer is spread across a dozen tabs and five tools. It turns that into concrete actions, a briefing page in the morning, cross-tool retrieval during the day, a remembered split layout for meetings, and slides at delivery time. Profiles solves the older problem of work and life sharing one browser. For anyone who lives in a browser for eight hours, the saving is in switching windows and rebuilding context.
