Choosing the best AI tool for writing essays depends on your needs. Grammarly stands out for its robust grammar and plagiarism checks, broad integration, and ease of use.
It was even rated best overall in TechRadar’s roundup of 2025 AI writers. But for deeper writing support, like outlines, AI detection, and citation help, tools like Litero AI and EssayCheck.ai offer more specialised academic features.
Students report that nearly all of their essay work benefits from AI assistance: 93 % of U.S. students say they use AI tools regularly to improve writing, citing help with brainstorming, summaries, and revision.
In short, Grammarly is the best starting point for most students. But if you need essay-specific help, add a specialised tool for structure and academic rigour. That combo offers the most powerful support for writing essays that are clear, authentic, and well-crafted.
