A Sentence-Based Language Learning Application (that is not much more cognitively exhausting than doom-scrolling)

Idea

1. Learner learns the vocabulary needed to understand a specific foreign language sentence
2. Learner is challenged to translate the sentence
3. Repeat

Tech

• Sentences are sourced (mainly) from Tatoeba
• Sentences were split into parts (=needed vocabulary) and auto-translated via an LLM
• The app itself is Vue+TS+DaisyUI+Tailwind with JSON files as data source
• Data preparation was done in python

Links

• frontend repository, data prep repository, data repository
• Infinite Sentences Webapp

Evaluation

Works pretty well and is decently fun. It does get a bit boring, because there rarely is a fun or unexpected “event” happening. Long-term retention is questionable, since sentences are not repeated after “solving” them once.
