SkypeTrance was designed to be a software module allowing automatic translation of chat messages in Skype from English and French to Bulgarian and from Bulgarian to English and French.

Sensible, not literal translation is a challenge to many people learning a foreign language. The goal of WebTrance is understandable translation of complete sentences, not just another computer dictionary. Following this goal, WebTrance is constantly being improved.

Of course, no computer program can deliver a 100% accurate translation, especially in cases where the meaning of many words and even whole sentences depends on the context.
