# Overview

> Property types that embed rich communication surfaces on a record.

## Communication properties

Communication properties attach a rich, collaborative surface to a record
instead of a simple scalar value. A
[Spreadsheet](/data/properties/communication/spreadsheet) property embeds a
live spreadsheet, and a [Whiteboard](/data/properties/communication/whiteboard)
property embeds a free-form drawing canvas. Both stored with the record and
editable in real time.

Use these when a record needs working space: a planning grid, a diagram, a
shared sketch, rather than a single typed field. They render inline on the
record and persist alongside its other properties.
