4 tools selected and reviewed
Having a paper rejected on the quality of its English before it is even assessed on substance is a familiar frustration for non-native researchers: journals expect a high standard of linguistic rigour.
These tools correct grammar and style, but above all they recognise the academic register that scientific journals expect, which a general-purpose checker does not.

Frequently asked questions
What is the best AI for correcting scientific English before submitting a paper?
Paperpal is built specifically for academic writing: it corrects the language and checks compliance with the style journals expect. Grammarly is more general-purpose but solid for everyday grammar and clarity.
Should you translate your paper with DeepL or write it directly in English?
DeepL gives a good translation base from a text written in French, to be reworked afterwards with a tool like Paperpal for academic register. Writing directly in English, even imperfectly, and then correcting with these tools often reads more naturally.
You work as researcher and want to automate “polishing your scientific english before submission”?
