## What it is
jscanify is an open-source pure JavaScript document scanning library powered by OpenCV.js. It detects and highlights documents in images and extracts them with perspective distortion correction, running in the browser, NodeJS, or React.

## Use cases
- scan documents from images in the browser
- detect and highlight paper in a photo
- extract and undistort a document from a camera image
- build a mobile-style document scanner web app
- process scanned document images in NodeJS

## When to choose
- you need client-side document scanning without a paid SDK
- you want a lightweight JavaScript library for paper detection and perspective correction
- you need it to run in browser, NodeJS, or React with the same API

## When to avoid
- you need full OCR text extraction rather than image extraction
- you need native mobile performance or advanced scanning features like multi-page PDF export
- your project cannot load the OpenCV.js dependency

## Facets
- artifact type: library
- maturity: active
- function: computer-vision, image-processing, ocr
- domain: computer-vision, image-processing, web-development
- platform: browser
- tags: document-scanner, opencv, paper-detection, distortion-correction, react, nodejs, javascript
