Spell checker
In computing, a spell checker (or spell check) is an application program that flags words in a document that may not be spelled correctly. Spell checkers may be stand-alone, capable of operating on a block of text, or as part of a larger application, such as a word processor, email client, electronic dictionary, or search engine.

Miss Steaks I can knot sea.
Eye strike the quays and type a whirred

Eye trussed too bee a joule.
The chequer pours o'er every word
Two cheque sum spelling rule.
