What feature allows users to see how many characters remain in a Text Input field?

The feature that allows users to see how many characters remain in a Text Input field is the remaining character counter. This counter actively updates as users type, providing immediate feedback on how many characters they can still enter before reaching a predefined limit. This enhances the user experience by helping them adhere to constraints without needing to perform calculations or guess how much space they have left.

A character limit primarily sets a boundary for the number of characters that can be input but does not visually display the current count of remaining characters. Placeholder text serves to give an example or hint about the expected input but does not provide real-time feedback regarding character limits. Tooltips are generally used to offer additional information on demand but are not typically associated with tracking character input or limits directly. Thus, the remaining character counter is designed specifically for the purpose of displaying current character count in relation to the set limit, making it the most suitable choice.
