What is the best grammar checker for academic writing?

The right one depends on how you edit. StudySim explains each suggestion so you can judge it, which helps when a fix might change your meaning. You stay responsible for the final draft, the facts in it and your course's formatting rules.

Can it check sentence structure?

Yes. It gives grammar and sentence-level suggestions next to your draft, each with an explanation. Suggestions can miss context, so read them before you accept. To rework a whole sentence, try the paraphraser.

Is there a grammar checker without AI?

This one uses AI and counts toward the shared AI usage limits. If you only need length checks, you can convert words to minutes and count characters in your browser without AI.
