Show HN: Turn your iPhone into a local OCR server using Vision Framework

Built an iOS app that runs a local OCR server using Apple's Vision Framework.

Creates a REST API endpoint accessible from any device on your network. No cloud services needed - everything processes locally on the phone.

Available on App Store (searching "OCR Server").

Would appreciate feedback on the architecture or similar mobile-as-server projects you've seen.

Cool - although I can't help to think that running a macOS VM and run the Vision Framework tool on it will be less clunky in the long run. Phones don't like to run with screens on 24/7 etc.
