That’s a cool approach. Running OCR locally avoids the usual privacy and latency trade-offs, and turning the phone into a network-accessible endpoint is clever.

Curious about performance — how fast is the Vision Framework on-device compared to something like Tesseract or cloud OCR APIs? And does the app stay responsive if the phone is handling multiple requests at once?

I tested it on my iPhone SE 2, and the performance was not great. I’ll run new tests after I get a new iPhone.
