Grammarly gives style advice too. It focuses on clarity, engagement, and delivery. Its tips are helpful but more general. It won't dig as deep as ProWritingAid does.
For example, ProWritingAid might flag 15 overly long sentences in your report. Grammarly might point out 5 that are hard to read. Both help, but one gives more detail.

Good writing uses the right words. These tools suggest stronger verbs or point out repeats. They help you find that perfect word.
ProWritingAid has a great focus on word choice. Its “Thesaurus” report is very handy. It shows you words you use too often. You can click on them to find new options right away.
Grammarly also makes word suggestions. They pop up as you write. Its advice is often about making your tone more formal or confident. It's good for quick upgrades.
However, ProWritingAid gives you more control. You can see all your “glue words” or “vague” terms in one list. This makes it easier to fix your whole document at once.
Winner: ProWritingAid. Its detailed reports on repeats and weak words are unmatched. It turns a good vocabulary into a great one. You will learn many new words.
Plagiarism Checker
A plagiarism checker sees if your writing matches other online work. This is key for school to avoid copying. It gives you peace of mind.
Grammarly includes a good plagiarism checker in its Premium plan. It checks over 16 billion web pages. It's reliable and easy to use with one click.
ProWritingAid has a checker too, but it's an add-on. You must pay extra for it on top of the Premium plan. This makes the total cost higher.
