Question 1

Is the grammar checker free?

Accepted Answer

Yes, the basic grammar check is completely free. You can use it without signing up. For advanced proofreading, editing, and polishing, the AI Editor is available.

Question 2

What is the difference between the grammar checker and the spell checker?

Accepted Answer

The spell checker focuses on surface-level errors like typos, spacing, and misspellings. The grammar checker focuses on grammatical errors like subject-predicate agreement, tense consistency, and sentence structure. OrangeRefine's AI Editor checks both at once.

Question 3

Why is 'the reason is... because...' incorrect in Korean?

Accepted Answer

This is a subject-predicate agreement error where the subject ('reason') and predicate ('because') overlap in meaning. It should be corrected to either 'the reason is...' or 'it is because...'.
