Kalba

Kalba is a language learning tool based around the idea of sentence mining. It has the following features:

• Use websites, files or the clipboard as input
• Automatically fetch definitions (with prebuilt and custom dictionaries)
• Automatically export words to Anki
• Automatically detect words known based on Anki ratings

Kalba is designed to be extensible so that users can configure it for any language. However, it also comes with out of the box support for several languages, with more planned.
