Wika
Production · 202601 / 05AI language-learning app for Philippine regional dialects, grounded in a retrieval corpus rather than in what the model happens to remember
Wika teaches the Filipino regional languages that general-purpose models are worst at. A custom RAG pipeline grounds every conversational turn in a per-dialect corpus, so a translation is backed by a real dictionary entry instead of a guess — and when the corpus has no good answer, the app says so rather than inventing one. The same backend generates lesson content and speaks replies back with pronunciation built per dialect. Started as a 72-hour Developer Camp hackathon build; now the production platform behind Wika PH, where I am co-founder and CTO.
