Readlang is probably my top resource now for learning new languages. Whenever I don't feel like studying properly, I can just read an article in a foreign language and enjoy it, without having to worry about looking up words that I don't understand. It makes reading in a foreign language a much quicker and more enjoyable experience!
It is difficult to give something that is so young a five star rating, but this is already one of the best sites (along with stuff like Anki, Memrise, "X"Pod, Duolingo, LingQ, etc.) around for this and it is only getting better.
I love being able to upload videos from YouTube and sync the lyrics to them [...] And, the ability to instantly have words that I click on made into flash cards (that can be exported to Anki) is great, too. This site has so much to offer. :)
This is one of the most fantastic language learning tools I have ever encountered. I can progress quickly through a book I’ve never read, and more importantly, it’s enjoyable [...] and it serves as a great set of self-made index cards.
