Grammar and style in scientific writing
Scientific writing has specific conventions that differ from everyday prose: past tense for reported results ("we found"), present tense for established facts ("the reaction produces"), passive voice in Methods sections, and hedging language for uncertain conclusions ("may suggest", "appears to indicate"). This AI checker understands academic context and flags issues accordingly rather than applying generic grammar rules.
The five most common grammar errors in research papers
Dangling modifiers ("Using this method, the results showed" — results cannot use a method), incorrect tense shifts within a section, run-on sentences without clear connectives, ambiguous pronoun reference ("it", "they", "this" without a clear antecedent), and subject-verb disagreement with collective nouns ("data were collected", not "data was collected" in formal scientific writing).
How to use this tool effectively
Submit one section at a time (200–800 words) rather than an entire manuscript. Review every suggestion — the checker may flag intentional stylistic choices. Use the corrected output as a draft, then apply your own editorial judgment about what to accept.
