What users say
Pros
- Catches the grammar slips and comma problems that other checkers let through.
- Tightens and polishes entire book manuscripts before professional formatting or proofreading.
- Reports on repetition, sentence length and readability show patterns across a whole book.
- Academic preset aligns feedback with research-paper conventions and formal scholarly style.
- Expanded explanations clarify why a suggestion was made rather than presenting unexplained corrections.
- Reports provide deeper and more customizable style analysis than Grammarly.
Cons
- Suggestions can be heavy-handed, flatten personal voice or even change the meaning.
- Glitches, lag and wrong scores get in the way on long manuscripts.
- Recent updates have degraded core report quality while adding unwanted generative AI features.
- The report-heavy interface creates a steep learning curve.
- Advanced reports and sentence polishing require the paid version, limiting the free tier.
