# SpellChecker for WPF and Silverlight Overview

## Content

**SpellChecker for WPF and Silverlight** is the WPF and Silverlight version of [SpellChecker for WinForms](https://developer.mescius.com/componentone/docs/win/online-spellchecker/overview.html), a mature component that provides the fastest, easiest to use, and most flexible solution to checking spelling available on the market. It uses the same engine that drives [ComponentOne IntelliSpell](https://developer.mescius.com/componentone/docs/win/online-intellispell/overview.html), our add-in for Visual Studio that allows you to check spelling in your applications for mistakes in forms, web pages, and comments used to generate XML documentation.
