Contextors is developing a technology to perfect the way computers understand natural language. The companys parser assigns syntactic structure trees to strings of words in English, and its voice conjugator changes the voice of English sentences from active to passive and vice versa.

Contextors also has developed Literate, which helps users master English by combining extensive reading with intensive inline learning support. By providing eBook readers with context-specific definitions, explanations of grammatical rules, and adaptive challenges, Literate presents users with the rules of English in context with their usage. Its adaptive learning capabilities allow the program to automatically adjust to a students learning level.
