About Chinese365
Chinese365 is an AI-powered Chinese language platform built around the Chinese Language Knowledge Base — a structured dataset of characters, words, grammar points, HSK vocabulary, pinyin, stroke order and usage examples. Unlike traditional Chinese learning apps, Chinese365 focuses on Chinese Learning Intelligence: instead of just feeding you lessons, we diagnose what you actually struggle with — tones, measure words, 了 vs 的, word order — and generate personalized practice.
Our tools are designed for English-speaking learners of Chinese. Use the Pinyin Converter, Character Decomposer, Grammar Checker, and HSK Level Test for free. Developers can access the same intelligence through our Chinese Language Intelligence API.
