Metanoia
Universal Biblical Corpus
& AI Voice Platform
Metanoia is a high-performance cross-platform Bible reader built for discovering unedited ancient texts. Featuring complete multi-canonical indexing across Masoretic, Septuagint, and Ethiopic traditions, native local AI voice generation, and deep-linking integration.
Engine Architecture
Designed for speed, modularity, and empirical validation across Linux, macOS, Windows, and Android.
Native Zig Engine
Built with Zig 0.17+ for zero-overhead performance, instant startup, and memory safety. Interoperates directly with GTK4, SQLite3, and native C runtimes.
Android App & Deep Links
Full Kotlin Android app featuring native intent handling, custom URI scheme registration, and seamless verse navigation matching the desktop engine.
Native AI Voice & STT
Integrated PyTorch & native aikit support running Qwen3-TTS (12Hz models) with real-time Faster-Whisper audio transcription and verification.
Universal Biblical Corpus Indexing
Empirical, historical transparency across all manuscript traditions without canonical concealment.
Core Indexing Principles
1. No Hiding
Search returns ALL matching books across Protestant, Catholic, Orthodox, and Ethiopian canons without silent filters.
2. Tradition-First
Organized by original textual tradition: Hebrew/Masoretic → Greek/Septuagint → Ge'ez/Ethiopic → Greek NT.
3. Historical Transparency
Explicitly surface books missing from the Protestant canon (1 Enoch, Jubilees, Tobit, Wisdom, Maccabees, Meqabyan).
Masoretic Tradition
39 Books of the Hebrew Canon (Torah, Nevi'im, Ketuvim). Full Hebrew interlinear data and verse mapping.
Septuagint (LXX)
Greek Old Testament canon containing the Deuterocanonical books (Wisdom, Sirach, Tobit, Judith, Baruch, Maccabees).
Ethiopic Canon
The broadest biblical canon in Christendom, preserving 1 Enoch, Jubilees, and 1-3 Meqabyan in Ge'ez textual history.
TTS + Whisper Voice Engine
Benchmarked voice synthesis with real-time speech-to-text verification.
TTS + Whisper Audio Accuracy Benchmarks
Tested on CUDA (GTX 1070) with Qwen3-TTS voice models and Faster-Whisper transcription backends.
| Scripture Passage | Voice Model | Whisper Model | Accuracy | Status |
|---|---|---|---|---|
"In the beginning God created the heavens and the earth." |
tommy | base | 100.0% | EXCELLENT |
"The Lord is my shepherd, I shall not want." |
tommy | base | 100.0% | EXCELLENT |
"For God so loved the world." |
tommy | tiny | 83.3% | GOOD |
💡 Recommended Audio Configuration
Use the "tommy" voice with the base Whisper model for 100% transcription accuracy on scripture passages over 7 words.
