All good things must come to an end. Unfortunately, that time has come for and Byki List Central, which are no longer accessible. Byki Deluxe Edition is also no longer available for purchase from Transparent Language.

If you are an existing user of Byki Deluxe, it may still work on your current device and operating system, but we will no longer be providing updates. Limited technical support will be available through the end of 2017.

For customers who have purchased the Byki Mobile app, the app will still be accessible and continue to work on your phone. For now, you will still be able to purchase new languages and regular bugfixing updates will be provided, as needed.

Byki was created to help language learners master vocabulary. Over the last decade, we've grown our technical capabilities and our knowledge of language acquisition, both of which we have use to create Transparent Language Online, a more robust language learning platform. Designed to help you develop far more than just your vocabulary, Transparent Language Online includes all of the Byki vocabulary you know and love, as well as new courses, learning activities, speech recognition technology, grammar materials, and more. Existing Byki customers can use the code BYEBYEBYKI to receive 30% off a subscription to Transparent Language Online.
