Write Away

 It's a tool designed for students to practice writing.
Since you are writing your essay, it would show you the usage of every word you typed immediately.
Also, it has academic , general ,overused category, making users choose by their need.
It's ,a good way to improve your writing in phrase,
but it is my suggestion that it would be better for learners to enter the topic he/she want,
then it has an example with better vocabulary and structure for him/her to take a look.
Because imitation is a better way for me to learn a skill,
and I believe learners could have bigger progress.
