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.

AI-native browser that understands your context and runs agent tasks
Reference tabs, tab groups, local files, highlighted text, whole pages, or screenshots as context with a single @ or one click, so you never copy-paste background material again.
Describe a routine in plain language and Tabbit's agent opens pages, fills forms, and carries out repetitive operations for you.
Choose among several leading models including DeepSeek, Kimi, GLM, MiniMax, Doubao, Qwen, and LongCat depending on the task.
Tabs are automatically grouped, categorized, and summarized in a vertical sidebar, making dozens of open research pages manageable.
