Cloud OCR Snip is a free and open-source OCR tool for Windows that is based on Google Cloud Vision. Here this is fully functional OCR software that you can use to select and extract text from images or from areas on the screen where the text is not selectable. It uses Vision API of GCP as OCR engine to process the image and precisely extract the text from them.

If you have used screenshot software then it works kind of in the same fashion. It keeps running in the background and whenever you need it, you can simply activate it from the system tray of Windows 10 and Windows 11. You select the region on the screen or image where the text is and then it will take care of the rest. Right now, it supports English only with 1 other language. In the later updates, it might be able to support more languages.

Google Cloud Vision is a high-powered machine learning based computer vision platform available as a service. It has very high accuracy and can detect various features inside images and photos including the text. It has a decent free plan where you can make 1000 requests every month. But using it requires programming knowledge. Luckily, Cloud OCR Snip solves that for you. This software works as a wrapper for Google Cloud Vision API to perform OCR.

Closing thoughts:

Cloud OCR Snip is probably the most powerful OCR tool I have ever used. The best part is that it is open source so it is unlikely that your GCP credentials will be stolen or compromised as you can always build the software on your own. Also, if you want to take a deep dive into its source code then you are allowed to do that as well. I liked the way it works and the best part is the accuracy. It works exceptionally with English language. And I am sure that in the coming updates, it will work perfectly with other supported languages as well.
