Resources and tools
Resources for research, teaching and the classics on this site.
AI study assistant
Ask about characters and Chinese at any time. Answers rest on reviewed explications and say whether a point is reviewed, pending or a candidate; it can be wrong and does not replace the book's readings.
Rationale database
A WordPress plugin and the hub of research and teaching: nodes, composition edges, senses and review status; AI-suggested readings are candidates only.
Project roadmap
The roadmap of the project to uncover the design of Chinese and its script.

Data resources
- cjkvi-ids (88,937 entries): for the form-layer pipeline and structural decomposition. Note: an IDS decomposition belongs to the common-reading layer and is not the New Six Scripts decomposition.
- The Shuowen Jiezi and other classics: the sources of the common readings.
- Unihan: external ground truth for strokes, radicals and other form properties.
