Dr.BigBrain is an open, free educational service currently focused on language education. Specifically we're currently only featuring lessons to help people learn to read simplified chinese.
Soon we will add the ability to contribute new lessons to DrBigBrain for others to use. Stay in touch, or contact us if there's something you'd like to see.
Dr.BigBrain is open-source. If you'd like to contribute to the code, see our section on GitHub.
The project started as a labor of love by Leo Dirac in the year 2000 before his first visit to China.
