Strongly recommend for all Japanese learners
Very powerful and versatile tool-able to input by hiragana/katakana/handwriting and has a huge vocabulary database, from technical terms to everyday slang. Other features such as flashcards and preloaded vocabulary study lists by JLPT level and language topic are also extremely useful. Would recommend to Japanese learners of all levels for sure.
