Could you build this?
Partial Building a CLI or GUI wrapper around existing open-source OCR engines (like Tesseract, PaddleOCR, or ONNX-quantized models) is straightforward, but achieving truly fast, accurate CPU-only OCR requires deep optimization of model quantization and native SIMD execution.
What it would actually take: A production implementation requires an optimized C++ or Rust inference engine running quantized lightweight models (e.g., PP-OCR or Fast-ViT with ONNX Runtime or GGML/OpenVINO). It requires tuning AVX-512/NEON intrinsics, efficient preprocessing pipelines (image normalization, binarization, PDF page rasterization), and cross-platform desktop integration. Specialized knowledge in low-latency computer vision and native embedded runtimes is needed to rival native speed on low-end CPUs.
