A desktop RAG (Retrieval-Augmented Generation) application for EPUB books.

Select an EPUB file, Nabu chunks and indexes it using Ollama embeddings, then lets you ask natural-language questions — answered with context from the book.

Stack: Tauri v2 (Rust) + React/TypeScript + Python (subprocess) + SQLite-vec
