Hack Chinese is a well-built tool. It earns its reputation among vocabulary-focused learners for good reasons.
Hack Chinese's vocabulary coverage is broader -- 100,000+ words with audio compared to our 10,000+ across HSK 1-9. For pure vocabulary grinding, they have more content.
The real question is what you mean by "learning Chinese." If it means recognizing and recalling words, Hack Chinese is efficient. If it means reading Chinese text, understanding spoken Chinese, producing accurate tones, and tracking readiness across multiple skills -- that is what Aelu is built for.
Hack Chinese is $12/month. Aelu is $14.99/month. The difference is scope.
"I know 2,000 words but can't have a conversation." -- the moment a vocabulary tool reaches its limit.
