The AI-powered interface for every database you run
Type a question in plain English and get an instant answer drawn from your connected data, without writing SQL by hand.
The AI editor reviews your SQL, corrects mistakes and suggests improvements, then turns result sets into presentation-ready charts automatically.
A snappy grid built from scratch for fast navigation of large tables, with customizable table plugins and edit-in-place controls.
Compose analytics boards manually or hand them to the AI, then embed charts anywhere using open-source web components.

The collaborative whiteboard built for product builders
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.
