Free Chinese Learning Tools

Small, free tools built on open Chinese data (CC-CEDICT and the HSK word lists). They run in your browser, need no account, and don’t send what you paste or upload to a server.

Looking for background first? The HSK 3.0 vs 2.0 guide explains what changed level by level, and the guides cover reading native Chinese and sentence mining. These tools are made by Minh, the developer of Zhenzhu, a popup Chinese dictionary for the Mac.
