The spellchecker verifies spelling in the TinyMCE editor. See also [Edit content using the TinyMCE rich-text editor](docId\:nlEKXoyI1idW3Bsc2hkge).

Click **Spell Checker** to check your spelling in the rich-text editor. Spellchecker highlights words with alternative spellings; you can click the word to see the alternatives.
