Find, save, and spec interior products in one workflow
Search by room type, colour, or a natural-language prompt to find interiors and the individual products credited inside them, with photographer and designer attribution.
Drag-and-drop boards for products, finishes, and materials that you can share with clients and teammates for comments and approval.
Turn a board into a real-time schedule your studio can price, with product data carried over instead of retyped into spreadsheets.
Lasso or pin a region of a rendering to swap finishes and adjust lighting, from day to night, without leaving the platform.

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.
