Hope to import a custom word list for learning

I hope to import a custom word list for learning, which can be in CSV format or directly pasted. The word list can have one word or phrase per line, and a translation may be added after a colon. You can set the number of lines to import each time. AI needs a dialogue inquiry function. Currently, synonyms are just listed as synonyms; dialogue can better address the needs of learners, allowing them to understand and remember the word more deeply.

Works better than expected

This is a hidden gem. I always struggled with improving vocabulary and learning new words but this app changed it. I love auto-play feature and use it all the time while driving to office. learning words via notifications is also very creative. Overall a very useful app and highly recommended.
