A free online grammar check specifically for academics

Help your research get heard

Poorly communicated research is simply less likely to be published in academic journals. Communicating science in the English language can be difficult and confusing. Native and non-native English speakers, regardless of their language skills, should have their manuscripts reviewed before submission.

The AJE Grammar Check tool can help you determine the clarity of your academic paper, find grammatical mistakes, and ensure a better understanding of your research within your area of study. With AJE's Grammar Check, researchers can think about their next research project and let AJE think about the grammar in their academic paper or grant application. Start your grammar check here.

The benefits of checking your grammar

Avoid rejection due to poor grammar

Papers can be in a journal's peer review queue for many months, sometimes years. According to a study in the Journal of Epidemiology, 62% of accepted submissions were rejected at least once. A paper's rejection after a long-awaited response can be frustrating for any author. Imagine the frustration if the article were rejected due to an avoidable issue, like poor grammar.

The AJE grammar check tool is free to use. And if your paper is submission-ready, our proprietary system will make you aware.

Get peace of mind with a free grammar check

Get results in minutes

Only 7.6% of manuscript submissions to Nature journals were published in 2017.

Researchers often work long hours and late nights to solve real-world problems. Much of that research deserves to be heard, yet only a small percentage make it into the most competitive journals. Don't let grammar be the reason why your paper was rejected.

There are many reasons a paper may need expert assistance : an edit or review to ensure your language is clear to your audience, a full translation by a native English speaker with an advanced degree to help share your research with the broader community, or formatting to meet the requirements of a specific journal. Whatever the case, we have the expertise and solutions to help. Get peace of mind by checking the grammar in your academic paper.

How clear is your technical writing? The AJE Grammar Check tool takes context and sentence structure into account when analyzing your academic manuscript.


A common problem with academic writing is inconsistency in the use of abbreviations or technical terms. Our tool looks for these key signals when performing its analysis.

What is AJE's Language Quality Score?

After a paper has gone through the grammar check process, the paper is given a quality score of 0-10. The Language Quality Score was developed by AJE and is designed specifically for the field-specific language commonly used by researchers.

The higher the score, the better the use of English within the submitted academic paper.
