Comprehensive grammar, style and register check for research papers, theses, and academic submissions. Powered by the LanguageTool public API.
Research paper checking applies the full set of LanguageTool rules, including those most relevant to academic writing: hedging language, passive voice, numerical agreement, citation formatting hints, and consistent tense usage. It doesn't replace expert review but catches the surface issues that distract reviewers from your argument.
Paste your paper or chapter (typically 1000–10000 words). The tool sends the text to LanguageTool, parses every match, and highlights issues inline. Each issue includes its category and suggested fix.
Use it before submitting to a journal, before final advisor review, after every major revision round, and as a final pre-submission sanity check. Don't substitute for peer review — use as a first pass.
Academic style favours precision: avoid 'a lot' (use 'many' or specific numbers), avoid 'thing' (name the concept), avoid 'really/very' (use stronger adjectives). Many of these are flagged by LanguageTool as register issues.
No — only formatting issues that look like missing citations. Cross-check against your reference manager.
No hard limit, but the public API may rate-limit on very long texts. For papers over 10,000 words, check section by section.
It treats unknown technical terms as potential typos. Add them to a personal dictionary in your editor for cleaner future checks.
