What is Felt and how does it function? Felt’s drawing tools offer a simple and enjoyable way to create maps. The Marker, Highlighter, and Notes tools enable users to interact with a map as if it were a notepad. Additionally, the Route and Clip tools, which are map-aware, make it effortless to draw along roads and boundaries. Furthermore, Felt allows maps to be internet-native by incorporating features such as Photos, Links, and Videos.
