Divvun Runtime

Modular language processing pipeline system for building grammar checkers and text-to-speech applications.

Define pipelines in TypeScript, compile to efficient Rust runtime, distribute as single-file bundles.

Features

• TypeScript Pipelines: Define text processing workflows in TypeScript
• Modular Architecture: Composable modules for HFST, CG3, spell checking, and TTS
• Bundle Distribution: Package pipelines with assets into .drb files
• Cross-platform: Rust core with Swift/Java/Deno/Python bindings and CLI tools
