Bing Spell Check API

Help users correct spelling errors, recognise the differences amongst names, brand names and slang, and understand homophones while they type.

See for yourself

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