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.
