Probably every high school teacher since the dawn of time has asked his or her students to have someone else proofread their essays before turning them in for a grade. Unfortunately, students don’t always comply with that request. And even when they do get someone to proofread, some items might go undetected. That’s why an online writing analysis tool can be helpful to students. Here are three free services that help students analyze their writing.

Paste your text into Analyze My Writing and it will generate a ton of information about your writing. Analyze My Writing will give you a break-down of the readability of your writing on five indices. The analysis will include listings of the most common words and most common word pairs in your writing. A listing of how frequently you use punctuation and punctuation types is included in the analysis provided by Analyze My Writing. Finally, a word cloud is included at the end of the analysis of your writing.
