Spell Check As You Type (SCAYT) allows the user to see and correct misspellings while typing. Misspelled words are underlined. Web Spell Checker (WSC) operates in a separate browser window so your work is not obstructed. Corrected text after web spell check is automatically returned. Both WebSpellChecker and SpellCheckAsYouType are compatible with HTML editors such as FCKeditor/CKEditor, TinyMCE spellchecker, HTMLArea, TextArea, text boxes.
