Turn tab chaos into a clean, AI-organised workspace with a visual tab universe
ATO reads page content and clusters tabs into meaningful categories such as Research, Shopping, Finance or Work.
Organise by category, last access, AI-predicted frequency of use, or custom topics you define yourself.
Enable on-the-fly mode and every newly opened tab is grouped the moment it appears.
A visual command centre where windows are Spaces, groups are Planets and tabs orbit as Stars, with drag-and-drop and marquee multi-select.

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.
