OnlineCorrection.com
Maklabu
OnlineCorrection.com finds and highlights spelling errors, as well as many basic grammar and style mistakes, in English texts, and offers suggestions for improvement. When there are two or more correct options, you are prompted to choose one of them. Finding every error in a text is difficult, even for a professional proofreader. Computers are very good at finding spelling mistakes and can often pick up other kinds of errors. However, without a real understanding of the text, it is impossible for a program to discover all grammatical, stylistic, diction and factual errors. Therefore, especially for important texts, we recommend that you not rely exclusively on this (or any) tool, but use a professional editor or proofreader to ensure that your document is as good as it can be. -

Hemingway Editor
Hemingway Editor
Hemingway makes your writing bold and clear. It's like a spellchecker, but for style. It makes sure that your reader will focus on your message, not your prose. Too often, our words are like our thoughts — innumerable and disorganized. Almost any bit of writing could use some cutting. Less is more, etc. So, the Hemingway Editor will highlight (in yellow and red) where your writing is too dense. Try removing needless words or splitting the sentence into two. Your readers will thank you. Hemingway builds on the innovations of researchers of a field called “Readability.” These researchers study how understandable a piece of writing is. Part of that work involves trying to decide which U.S. grade level is required to understand your text. Hemingway judges the “grade level” of your text using the Automated Readability Index. It's a reliable algorithm used since the days of electronic typewriters. Now, when we say “grade level,” we aren't saying that's who you're writing for.Starting Price: $19.99 one-time payment -
