Prof Hanlexon is a voice-first AI tutor for Mandarin. Instead of open chat, it runs a short structured lesson: it picks what to teach from your progress, has you say each word out loud with instant tone feedback, then use it — and schedules spaced-repetition review. It covers HSK 1–9 and teaches only real vocabulary, never invented words.
How a lesson works
1. Hear it
Prof introduces a few words at your level — the character, the sound, and the meaning in your language.
2. Say it
You say each word out loud. Prof scores every syllable’s pitch against its tone — 你✓ 好✗ — and tells you exactly which tone to fix and how.
3. Use it
A short spoken exchange puts the new words to work, so you produce the language, not just recognize it.
4. Remember it
What you learn is saved to spaced-repetition review and resurfaces right before you'd forget it.
Why it beats a generic language app
Real speaking & tones
Per-syllable pitch feedback on your own voice — it hears that your “谢谢” rose when it should fall, and shows you. The hardest, most-skipped part of Mandarin.
Built for Chinese, HSK 1–9
Aligned to the HSK curriculum end to end, with character writing and a graded reading library.
Teaches your own material
Open any reading and “Learn with Prof” becomes a guided comprehension lesson: it pre-teaches the blocking words, walks the passage with meaning questions, then has you re-read it fluently.
Grounded, never invented
Every word and radical comes from a real dictionary/HSK dataset — the tutor explains structure, it doesn't make it up.
Questions
How is an AI Chinese tutor different from a chatbot?
A chatbot free-converses and leaves you to steer. Prof Hanlexon runs a structured lesson — it decides what to teach next, teaches a few words with audio and meaning, has you say each one and scores your tones, then has you use them, and saves them to review. You're taught, not just talked at.
Does it really check my pronunciation and tones?
Yes — and per syllable, not per word. Say 谢谢 with the wrong second tone and it tells you “the second syllable should fall” and re-models it. When the audio is too unclear to judge fairly, it says nothing rather than guessing wrong.
What levels does it cover, and is it free?
HSK 1 through 9, adapting to your level. There's a free tier; Pro adds unlimited daily AI practice.
Can it teach my own reading or worksheet?
Yes. Open any reading or worksheet and choose “Learn with Prof” — it pre-teaches the key words so the material makes sense, then hands you back to read or write it.
