MandarinAI vs Hack Chinese
Hack Chinese is a well-made, focused app — a fast spaced-repetition trainer for Mandarin vocabulary, with a deep catalog of HSK, exam and textbook word lists. It's a genuinely good tool. MandarinAI is built for learners who want the review to lead somewhere — into reading, context and stories — rather than staying inside a flashcard deck.
If your goal is pure vocabulary memorization against a specific book or exam, you'll be happy with either. The difference shows up in what surrounds the review: MandarinAI pairs the same spaced repetition with illustrated graded stories, example sentences and audio on every word, a free public dictionary, and short stories generated from the exact words in your deck. Here's an honest, side-by-side look.

Hack Chinese details were checked against hackchinese.com in July 2026. Features and pricing can change — see their site for the latest. Where Hack Chinese takes a different approach (for example, graded readers as word lists to pre-learn rather than in-app reading), the table says so rather than scoring it as a missing feature.

The verdict
Both apps are genuinely good at spaced repetition, and Hack Chinese is a specialist that does one thing extremely well: if efficient vocabulary memorization against a specific textbook or exam is all you need, its deep catalog of ready-made lists is hard to beat. MandarinAI is for learners who want that review to connect to context — the same words you study show up in illustrated graded stories and in stories generated from your own deck, with example sentences, audio, songs and slang guides alongside, and a free plan to start on. If “more than a flashcard app” is what you're after, MandarinAI is the stronger fit; if “the best focused flashcard app” is, Hack Chinese is a great choice.
