Bethel: Offline-first Bible Study App with a Theological AI Assistant
2026 - Present · Lameute · Cameroon
Read, study and pray, even offline, with a theological AI companion.
Built by EMANE BILE Felicien Davy, Software Developer & Digital Systems Engineer.
About this project
Free Bible study app to read, study and pray anywhere, even without a connection. Bible versions are downloaded once as local SQLite packages, and a theological AI assistant answers questions from real sources: Scripture, commentaries, dictionary and Strong's concordance. Published on the web, Android, Microsoft Store and Snapcraft.

- Theological AI assistant on a RAG pipeline (FastAPI) grounded in Scripture, commentaries, dictionary and Strong's, not speculation
- Hebrew and Greek interlinear, Strong's concordance and dictionary (87k entries)
- Hymns and worship library, reading plans, sermon and study preparation

- Backend on Django REST, FastAPI, PostgreSQL, MongoDB, Redis and Elasticsearch 8 for cross-resource search
- One React + TypeScript codebase shipped to web, Android (Capacitor) and desktop (Electron: Microsoft Store, Snapcraft)
