The AI browser that reads between your tabs
Starts the day with a consolidated view of your calendar, inbox and key links so you know what is coming before work begins.
Ask once and Dia searches open tabs along with connected Slack, Notion, Teams, GSuite and other tools to answer with full context.
Requests for a deck or a summary come back as presentable slides and shareable reports rather than raw chat text.
Surfaces where work is actually happening, like a specific pull request or spec draft, so one click lands you in the right place.
The Chrome website blocker that judges every page against your task
The extension reads each page and judges it against the goal you typed, so work-related YouTube or Docs stays available while feeds and Shorts are refused.
There is no one-click off switch. Ending a session early means typing a full surrender sentence by hand, letter by letter, with no pasting allowed.
Pick standard filtering, the Quit Wall, or a nuclear mode with no exit at all, and escalate on days when your attention is fighting back.
Every time you choose work over the feed the moment is stamped and timed, and banked minutes build into a weekly record of reclaimed time.
