The Smart TextArea goes beyond simple word suggestions by predicting full sentences based on user input. Whether composing emails, filling out forms, or drafting content, the AI-driven autocomplete feature minimizes typing time by offering smart, context-aware suggestions. These suggestions are not random but contextually relevant and precise, enhancing the overall input experience.
Inherited features
Since it’s built on top of Syncfusion’s Blazor TextArea component, the Smart TextArea inherits all the features of the TextArea component, including form support, floating labels, and customizable styling.
