## What it is
An iOS app that turns an iPhone into a local OCR server using Apple's Vision Framework, exposing an HTTP API and web interface for image text recognition. All processing happens on-device, offering unlimited usage with no cloud dependencies.

## Use cases
- extract text from images via a local HTTP API
- run OCR without sending data to the cloud
- test OCR integration during app development
- share an OCR service across a local network
- build a batch OCR cluster from multiple iPhones
- get bounding box coordinates of recognized text

## When to choose
- you need private, offline OCR with no per-request cloud costs
- you want a quick REST OCR endpoint using an iPhone's on-device ML
- you need text bounding boxes in JSON for downstream processing

## When to avoid
- you need server-grade throughput or headless deployment on Linux
- you require OCR on Android or desktop hardware
- you need long-running unattended service without iOS backgrounding limitations
