Tesseract is one of the largest Open Source OCR (Optical Character Recognition) projects. There is already a Go library for using Tesseract from Go with CGo, called Gosseract.

However if you are interested in OCR from Go without C complicating building and cross-compiling, there aren't any other options.

Wazero is a Go WASM runtime that doesn't have any CGo dependencies. With Emscripten Tesseract has been compiled to WASM and ran within Wazero.

Gogosseract provides a simple API on top of this. This project has been an interesting delve into the world of WASM.
