Could you build this?
Partial Running entirely on-device with zero cloud or backend requires fine-tuning or quantizing local models (CoreML / MLX / llama.cpp) alongside reliable deterministic legal-regex parsing engines under strict iOS memory limitations.
What it would actually take: The stack requires native Swift with PDFKit/VisionKit for local OCR and text extraction, paired with rule-based deterministic regex parsers and Apple Intelligence / quantized Llama models via CoreML or llama.cpp. The critical engineering difficulty lies in keeping on-device LLM context processing within iOS app memory limits (often capped at 2-3 GB per process without jetsam termination) when processing 300+ page PDF bundles. Developers need hands-on expertise in CoreML optimization, local embeddings, and on-device SQLite full-text search.
