- 📝 Grammar Analysis — Checks subject-verb agreement, tense consistency, article usage, and sentence structure
- ✨ Style Improvement — Suggests alternatives for passive voice, wordiness, redundancy, and clichés
- 📊 Readability Scoring — Calculates Flesch-Kincaid scores to help you match your writing complexity to your audience
- 🧠 Context Awareness — Understands meaning to avoid false positives and provide relevant suggestions
