Pruuf is a free, simple-to-use, and efficient tool for detecting and correcting spelling and grammar mistakes. Its purpose is to ensure that a piece of text you want to share with others is free of spelling and grammar mistakes. It works for all kinds of text: e-mails, business plans, scientific papers, and even informal texts, like messages and chat logs.

The first step is to install the English, Malay, or Chinese language version of Pruuf, depending on what you want to write about. Next, select the language for which you want to write and the text for which you want to see the correction results. Now you can start to write.

In the end, you will see a list of detected errors and suggestions for fixing them.

By default, the app will always check your spelling for you.
