I wanted Cangjie to give someone a small moment of wonder: to look at 山 and suddenly see the mountain inside it.
Astra made me more ambitious about how far I could take that moment. Working with Astra in Codex, I could bring together historical forms, illustrations, animation, pronunciation, and writing practice, and keep refining how they worked together. I could ask, “What would make this easier to understand? What would make someone curious enough to explore?” and then build and test those ideas.
That ambition included getting the details right. A beautiful animation needs context. A historical form needs a source. When the evidence is incomplete, the app should say so. Astra helped me work through those decisions alongside the design and code.
The result is an experience where you can follow your curiosity from a picture to a character, look closely at its forms, hear it, and try writing it yourself. Astra helped me give Cangjie the depth and care that the idea deserved.

Hi Product Hunt!
I'm Isabella, creator of Cangjie.
As a child, I learned that some Chinese characters originated from pictures of things in the world around us. That fascinated me. As I grew older, my love of reading, writing, and history kept bringing me back to these characters and the stories behind them.
I've wanted to build Cangjie for a long time: a visual guide that lets people explore Chinese characters and how their forms have changed over thousands of years. GPT-6 Astra finally helped me bring that idea to life, and I'm excited to share it with you!
Start with 馬 / 马, meaning “horse.” Watch a teaching illustration lead into selected historical forms, including the Oracle Bone Script, and compare them with today's Traditional and Simplified Chinese characters. You can look closely at the shapes, inspect their sources, hear the Mandarin pronunciation, and try writing the character yourself.
I want the experience to be playful and thoughtful. The animations help you compare shapes, while the sources and explanations keep the historical evidence visible - including where our knowledge is incomplete.
For the GPT-6 Astra Challenge, I worked with Astra through Codex to research, design, build, test, and refine Cangjie. It helped me connect the illustrations, form comparisons, animation, writing practice, and multilingual interface into something people can explore for themselves. Seeing an idea I'd carried for so long become a working app has been a joy.
Cangjie is free for everyone to explore. I built it for beginners, native speakers, academics, and anyone who is curious.
Try the horse character and tell me: What helped you understand its shape? What could I make clearer or more enjoyable?
I'll keep updating and adding characters and improving Cangjie, and I'd love your feedback along the way. Thank you for exploring it with me. I'll be here to answer questions and learn from you, too.
