duojp

Build sentences by dragging tiles.

Full-stack · Product

Problem

Turn a very large multilingual sentence corpus into a lightweight interaction that can produce useful practice repeatedly without a heavy application backend.

What I built

The product couples corpus processing and filtering with a compact browser interaction, then ships as a serverless web app that can draw from hundreds of thousands of sentences.

Live product

Use the thing itself.
