Have any in mind?

Not really - Word's works fine for me. There's also openoffice and google docs might have one too, the latter two being free to use.

Like for the writer, who goes and write these out and goes through it and trys to find any errors/gtrammar. But doesn't useually catches them and can read his/her own sentences A-okay. Minus the fact, that a reader may have trouble understanding and reading through it while, the author/writer can read it fine and dandy. Even though they've been told about the errors and mistakes. But can't find it alright in their eyes.

Quite true so beta readers help in that regard. However one technique I learnt of that works well imo is to proofread at least a full day after finishing writing of the chapter/piece of work before posting, and maybe longer. The break allows you to forget what is fresh in your mind ad hence you can look at your work more objectively.
