# What is the difference between SCAYT plugin for CKEditor 4 and WProofreader?

WProofreader is an alternative product for the SpellCheckAsYouType (SCAYT) plugin enabling extra functionality and a more convenient and freshly looking user interface with flexible customization options. Both SCAYT and WProofreader use the same engines and provide the same quality of spelling or grammar check. But when migrating from SCAYT to WProofreader you receive access to the additional features.

You can use WProofreader in:

* CKEditor 4 as well as for other text editors, for example, CKEditor 5, TinyMCE 4/5, Froala Editor, TinyMCE, Quill, Kendo UI (see the [demos](https://demos.webspellchecker.com/) on our website);
* HTML editable controls such as **input** and **textarea**;
* Elements with a contenteditable attribute such as **div**, **iframe**, and others.

WProofreader advantages:

* Modern UI, faster performance, and improved usability;
* More options for UI and behavior customization for both on-premise and cloud versions;
* Proofreading in a dialogue as the alternative proofreading mode;
* Spelling [autocorrect](/v6.12.0/features/spelling-autocorrect.md) and text [autocomplete](/v6.12.0/features/text-autocomplete.md) suggestions;

WProofreader cons:

* You need to add configuration scripts on your page where proofreading is required;
* Since WProofreader has a different user interface, users may need some time to familiarize themselves with the badge icon and proofreading options and commands available.
