What is the Bing Spell Check API?

Bing Spell Check API lets you perform contextual grammar and spell checking on a text string. While most spell-checkers rely on dictionary-based rule sets, the Bing spell-checker leverages machine learning and statistical machine translation to provide accurate and contextual corrections.


Feature Description
Multiple spell check modes Multiple spell check modes let you get corrections focused on grammar and/or spelling.
Slang and informal language recognition Recognize common expressions and informal terms used in text.
Differentiate between similar words Find the correct usage between words that sound similar but differ in meaning (for example, "see" and "sea").
Brand, title, and popular usage support Recognize new brands, titles, and other popular expressions as they emerge.
