eSearch: An Open Source Offline OCR Tool 

I have always been struggled with using OCR tools. The tools I used to use was either inconvenient or fee required. So I was wandering if there is any open source and free OCR tools that I could use.

Finally I found eSearch. eSearch is an open source offline tool developed by xushengfeng, which provides a lot of features,more than OCR. It supports screenshot + OCR + search + translation ...

eSearch support multi-platforms including Windows, Linux and Mac, because it's developed on electron.

You can download it from the official website of eSearch. 

The official document in English is on github repository
