To facilitate development of a new engine and lexicon, Microsoft has made the CSAPI specification available. Third parties that are interested in implementing only an add-in lexicon (such as medical, legal, or technical terms) but not an engine only require specific tools to convert their lexicon into the appropriate format and should be aware that this is only supported for English and CSAPI is not required.
Developers who are interested in implementing a CSAPI spell check engine and lexicon, or only an add-in lexicon, can contact Microsoft Developer Support. The following Microsoft Knowledge Base article contains the contact information:
Developers who want to add spell checking to their custom application can contact one of the following vendors to obtain a spell check engine and development license:
ComponentOne VSSPELL (formerly VideoSoft VSSPELL)
BeCubed AZSpell (formerly HighSpell)
