Hi HN,
I built an automatic deck builder for anki. As a non-native english speaker but avid reader, I find that I don't know many words while reading a book. While I can approximate the meaning, it slows me down and many times I move on with ambiguity. Sometimes the words are critical in the context but I don't like to pause and lookup in dictionary. Even if I do, I tend to forget them soon.Also, Anki is the best tool for long term retention but building a deck is cumbersome. So, I built this tool to extract the words from the book I am reading and add those to my anki deck.
It is free, give it a try and share your feedback or features you would like to see.
Thanks,
Pushpankar
