It's really difficult to get good books in a foreign language that matches you level, especially if you have just started to learn a new language and your vocabulary is very limited.

It would be a fantastic tool, if we had a "text simplifier" that would recreate a paragraph by replacing the rarely used words with their most common alternatives while trying to keep the meaning of that paragraph.

The list of most commonly used words in many languages are publicly available, so theoretically it would be possible to limit the output words to - let's say - the most common 400 ones in that language.

Just imagine how satisfying would it be, if you could re-read your favorite books in a foreign language that you are learning, and understand nearly everything! You could even increase the difficulty gradually as you learn more and more words!
