All translation services are available in demo for free. They are not limited anyhow in the time of using - they are limited by functionally. Using the demo-version you are enabled to receive only a part of translations. Please download dictionaries client and try translation services in demo.
Once you made your choice and decided to purchase our product, the only thing you'll have to do is to order from us a registration code that you'll have to enter into your trial version. After this activation all limitation of the demo version will be removed and you'll become user of a complete commercial version.
We really appreciate your choice!
