PhraseExpander RealSync™ technology is designed to allow easy sharing of phrases and autocorrects among PCs by creating a linked glossary, without the need of setting up a central server.
All that is required is having a folder that is shared among all the users who need access to the glossaries. Any cloud service would work as well.
When a user publishes some changes, PhraseExpander will detect them and keep the glossary in sync (you can optionally decide to accept or reject some changes and merge them in case of conflicts).
