Frequently asked questions (FAQs)
How is LexiCheck different from Grammarly?
Grammarly supports only English. LexiCheck checks spelling and grammar in over 100 languages and is designed especially for language learners. It also includes AI chat to help explain corrections.
Will LexiCheck corrections be flagged as AI-generated or plagiarized?
No. LexiCheck doesn’t rewrite your text—it simply highlights and fixes grammar and spelling mistakes. Your writing remains original and won’t be marked as AI-written or plagiarized.
How can I edit comments in the DOCX file?
To edit comments, open the file with Microsoft Word (desktop or online version): https://word.cloud.microsoft
Can I use Google Docs to open the corrected file?
Yes. Just upload the DOCX file to Google Drive to view or share it like any other Google Doc.
Note: Google Docs doesn’t support comment editing. For full control, use Microsoft Word to edit comments first.
