Introducing an English corrector app.

I'd appreciate it if you would correct it for me.

Writing an article must be grammatically correct, whether it is an essay or a letter.
As I far as I know there are lots of ways to check it. One of the best ways may be to use google translate or some other online applications.
But, personally, I am using an app to find errors in an article. It is called Grammarly. This application has been created by Google for people who are educated but cannot write well. I always use this app before sending a personal email to a native English speaker.
Using this has some bugs. it can't recognize plenty of complex grammar errors, so it is not foolproof, but it may take a lot of human errors, such as misused commas, semicolons etc.

I hope this  information is useful for your writing.
