Tablet mode is a mode on Chromebooks that creates a touch-friendly interface. Instead of the typical desktop layout, all your apps are shown in a scrollable list with large app icons.

For example, using them in tablet mode can be better for taking notes. Especially if you can use it with a stylus. Then you can use the clamshell form factor when you want to type.

Of course, Assistant Ambient Mode was far from a success. Lenovo announced a new tablet running Ambient Mode in January of 2020, while the experience expanded to OnePlus a month later.
