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.

Turn plain text into diagrams, infographics, and presentation-ready visuals.
Paste or import your text and Napkin generates infographics, diagrams, flowcharts, mind maps, and data charts that fit your content.
Napkin Slides collaborates with you to turn ideas into complete, ready-to-present decks rather than static images.
Adjust colors, fonts, layouts, and icons, reshape individual elements, and match your brand — nothing is locked after generation.
Export visuals as PPT, PNG, PDF, or SVG and drop them into PowerPoint, Google Slides, Keynote, Notion, or any tool you already use.
