Frequently asked questions
Are there free AI writing assistants?
Yes. Most tools on this list have a free plan or free tier covering basic grammar checks or a limited number of rewrites. Paid plans usually add longer content, more tone options and advanced features.
Is it allowed to use AI for university assignments?
Rules differ between institutions and courses, so check your university's policy and ask your teacher if unsure. Using AI to check grammar or understand feedback is often fine, but submitting AI-written work as your own can count as misconduct.
Will AI writing sound natural?
It can, but drafts often need editing. Add your own examples, voice and knowledge, cut generic phrases and check facts. The best results come from treating AI as a helper, not the final author.
Which assistant is best for non-native English writers?
Tools that suggest rewrites and explain grammar issues are especially useful, because they help you learn as you write. Try a couple on your own text and choose the one whose suggestions you find clearest.
