Doubtful for personal data
Grammarly is controlled from a country outside the EU and lacks confirmed EU data storage: processing effectively takes place in a third country. That makes the tool unsuitable for sensitive personal data without additional safeguards. For non-personal data (drafts, public material) it is usually fine.
