About HSK One — One Place. All HSK.

Quick Answer: HSK One is an independent, free Chinese learning platform aligned to the HSK standard. We build structured courses, exam practice, and spaced repetition tools that anyone can use without an account or payment. We are not affiliated with CTI/Hanban.

Our Mission

HSK preparation shouldn't depend on your budget or your country's app store prices. A student in Hanoi, a worker in Jakarta, and a hobbyist in Toronto should all have access to the same structured path from zero to HSK 1 — for free. That's the problem HSK One exists to solve.

What We Build

  • Structured courses: story-driven lessons covering the full HSK vocabulary and grammar syllabus
  • Exam preparation: mock tests in real exam format with instant scoring and explanations
  • Memory tools: SM-2 spaced repetition flashcards that schedule reviews at the optimal moment
  • Open content: every page is readable without JavaScript, indexed by search engines and AI assistants alike

Principles

  1. Core learning stays free. No trial periods, no feature gates on lessons or exercises.
  2. No account required. Start Lesson 1 in seconds; progress saves locally and can sync later.
  3. Honest claims. We are HSK-aligned and independently developed — never affiliated with or endorsed by CTI/Hanban.
  4. Performance is a feature. Pages load fast on slow connections because our users are everywhere, not just on fiber.

Meet Momo

Momo is our watercolor puppy mascot who 'travels' through Beijing in the course storyline. Momo doesn't track you, sell you things, or pop up uninvited — Momo just celebrates when you finish a lesson.
