MandarinAI vs HanziHero
HanziHero is a beautifully systematic way to learn Chinese characters through mnemonics and radicals — if character recall is your bottleneck, it's excellent at it. MandarinAI is a broader study loop: the same spaced repetition, but wrapped in reading, native audio and stories, at a lower price and with a genuine free tier.
HanziHero and MandarinAI overlap in the middle — both use spaced repetition to build Chinese vocabulary — but they aim at different problems. HanziHero is character-first: it teaches you to decompose hanzi into radicals and lock them in with vivid mnemonics, in a tightly structured order. MandarinAI is context-first: it drills words with FSRS, then pushes them into example sentences, graded stories and audio so they stick through use. Here's an honest, side-by-side look.
Side by side
| Feature | MandarinAI | HanziHero |
|---|---|---|
| Spaced-repetition scheduling | FSRS — a modern, open algorithm | Its own structured SRS |
| Character mnemonics & radical breakdowns | Stroke order + meaning, not full mnemonics | Systematic radical mnemonics — its core strength |
| HSK word lists | HSK 2.0 and all HSK 3.0 bands | Structured character & word progression |
| Native pronunciation audio on every word | Neural audio, words + sentences (Pro) | Character-recognition focus, not audio drilling |
| Example sentences on every word | Built in, with audio | Vocabulary in context, less sentence-first |
| Illustrated graded reading in the app | Read bound graded stories, page by page | Not a reading tool |
| AI stories built from your own deck | ~95% words you already know | — |
| Free plan | Free-forever plan (up to 200 cards) + 14-day Pro trial | Free trial; no permanent free tier |
| Starting price | Free · Pro $79/yr (~$6.58/mo) | $10/mo billed annually, $15/mo monthly, $349 lifetime |

HanziHero details were checked against their site in July 2026. Features and pricing can change — see their site for the latest. HanziHero's mnemonic system is a deliberate design choice, not a weakness — for pure character recall it's one of the best around. The dashes above mark features it doesn't set out to offer (audio drilling, in-app reading), not gaps in what it's built to do.

Different bottlenecks
HanziHero is unusually good at one specific problem: making Chinese characters stick. It breaks each hanzi into radicals, attaches a memorable story to each component, and schedules reviews so the shapes and meanings lodge in long-term memory. If your Chinese has stalled because characters slide off you — you can speak a little but reading feels like a wall — that focus is exactly what you want, and few tools do it as cleanly.
MandarinAI treats character recall as one part of a larger loop rather than the whole game. It uses FSRS to schedule vocabulary, shows stroke order and meaning, and then leans hard on context: native audio on every word, example sentences you can hear, and reading that reuses the words you've studied. The bet is that words stick best when you meet them again in sentences and stories, not only when you can recall a character in isolation.
Neither approach is wrong; they suit different moments. Early on, when characters are the obstacle, HanziHero's mnemonic drilling can be the faster route. As you move toward reading and listening fluency, the surrounding context MandarinAI provides starts to matter more.
Reading, audio & stories
The clearest difference is what happens after you've learned a word. In HanziHero, a learned character is a card you can now recall. In MandarinAI, it becomes an ingredient: it appears in example sentences you can play aloud, in illustrated graded stories you read page by page, and in short AI-generated stories tuned so about 95% of the words are ones you already know. That's comprehensible input built from your own deck, which is hard to get anywhere else.
Audio is the other gap. HanziHero is built around recognizing and recalling characters rather than drilling pronunciation, so it doesn't put native audio on every word the way MandarinAI does. If hearing tones spoken naturally — on the word and in a full sentence — matters to you, that's a concrete reason to prefer MandarinAI, or to run both.
Price
As of July 2026, HanziHero runs about $15 a month, or $10 a month billed annually (roughly $120 a year), with a $349 lifetime option. That's a fair price for a polished, specialized tool — but it is a meaningful step up from MandarinAI's Pro at $79 a year (about $6.58 a month), and HanziHero doesn't offer a permanent free tier the way MandarinAI does.
MandarinAI's free-forever plan gives you the full spaced-repetition loop on HSK lists, every word and example sentence, up to 200 active cards, and a weekly AI story — enough to genuinely learn on before paying anything. If you want to try the whole approach at no cost, or you're weighing $79 a year against $120+, the math is worth doing.
The verdict
If your single biggest problem is recognizing and remembering characters, HanziHero's radical-and-mnemonic system is one of the best-designed tools for it, and it's worth the price for that focus. But if you want spaced repetition that connects to listening and reading — native audio on every word, example sentences, graded stories and AI stories built from your own deck — MandarinAI covers more of the journey, starts free, and costs less per year. Many learners could reasonably use HanziHero to break through characters and MandarinAI for everything around them; if you only pick one broad study app, MandarinAI is the fuller loop.
Start free and read your first story built from your own words. Spaced repetition, native audio and graded reading in one loop, for less than the price of a monthly character app.
