Notebook supports real-time collaborative editing, enabling multiple users to work together, add comments, and mention others.

It also facilitates ad-hoc data extraction and complex analysis using flow-based documents (Doc Page) and SQL Blocks, allowing the creation of visually appealing charts arranged neatly in tile-based documents (Grid Page).
