Hanzi Master is a Chinese character learning-aid program for Mac, Windows, and iPad. It is designed to help you memorize characters and words by letting the structure they share work for you instead of against you.
In addition, Hanzim functions as a fast, easy dictionary: you can look up characters by Mandarin pinyin, Cantonese jyutping, radical, or English definition. Or paste a character from a browser or other place on your desktop for an instant view. Hanzim also includes a reader window where Chinese text can be loaded or pasted in and read with pop-up annotations.
