Why use an academic grammar checker?
General grammar checkers like Grammarly or LanguageTool are not optimized for academic writing. Academic manuscripts have specific requirements: passive voice is often appropriate in Methods sections; hedging language ('may suggest', 'appears to indicate') is expected; specialized terminology must not be flagged as errors. CheckMyManuscript's grammar checker understands academic writing conventions and checks grammar in that context, catching real errors while respecting legitimate scholarly style choices.
