Major features: ($ = paid add-on)
• Amazing dictionaries. We offer two free built-in dictionaries: the popular open-source CC-CEDICT, with over 110,000 frequently-updated entries, and our own PLC dictionary, with 125,000 entries, parts of speech, and over 25,000 example sentences (with Pinyin). More than two dozen other dictionaries are available as free and paid ($) add-ons, including licensed titles from well-known publishers like Oxford, Longman, FLTRP, Tuttle, SLPH, and Commercial Press.
• Powerful merged search: look up words by Chinese characters, Pinyin (spaces / tones optional), or English, with support for wildcards and full-text search. And no need to tediously flip between all of those dictionaries to find a word - just type in your search term and instantly get a combined, frequency-sorted result list.
• Links and cross-references: easily look up character components, break down words into individual characters, look up lists of words containing a particular character, and search across all dictionaries for example sentences containing a word.
• Gorgeous typography: see it for yourself in our screenshots - we think we're one of the best-looking Chinese dictionaries around. Alternate Kai/Song/Xing-style Chinese fonts are also available ($).
• PRC/HK/Taiwan-friendly: every part of Pleco supports both traditional and simplified, headword readings can be shown in Pinyin and Zhuyin, and some dictionaries even support Cantonese. (note: stroke order diagrams do support traditional characters, but use PRC order)
