Conversely means "in a contrasting way" or "on the contrary." It's used to introduce a statement that is the opposite of what was just said.
Example:
* "John loves to eat spicy food. Conversely, his sister prefers bland dishes."
Here, "conversely" indicates that John and his sister have opposite preferences regarding food.
