Bing Spell Check API

Help users correct spelling errors, recognize the difference among names, brand names, and slang, as well as understand homophones as they’re typing.

See for yourself

Try out the spell check capabilities. Switch between spell correction for web searches (‘Spell’) and documents (‘Proof’) from the top-left drop-down. ‘Spell’ is more aggressive in order to return better search results, while ‘Proof’ is less aggressive and adds capitalization, basic punctuation, and other features to aid document creation.
