## What it is
gosseract is a Go package that provides OCR (Optical Character Recognition) by binding to the Tesseract C++ library via cgo. It lets Go applications extract text from images with a simple client API.

## Use cases
- extract text from images in go
- run ocr on scanned documents
- read text from png screenshots
- build a go service that does ocr with tesseract
- convert image-based pdfs to text

## When to choose
- you are writing a Go application and need OCR via Tesseract
- you want a thin, well-maintained Go binding to libtesseract
- you need cross-platform OCR support including Linux, macOS, and Windows

## When to avoid
- you want a pure-Go OCR implementation without cgo or native Tesseract dependencies
- you need a ready-made OCR HTTP server rather than a library (use ocrserver instead)
- you need modern deep-learning-based OCR accuracy beyond what Tesseract provides

## Facets
- artifact type: library
- maturity: active
- function: ocr, image-processing
- domain: computer-vision, image-processing, developer-tools
- platform: windows, go
- tags: tesseract, cgo, text-extraction, leptonica, linux, macos, docker
