## Grammarly strengths

- Works across desktop, browser, Office, Google Docs and mobile keyboards, so suggestions follow you between apps.
- Free plan covers core grammar, spelling and tone visibility with 100 AI prompts per month.
- Pro adds tone adjustment, full-sentence rewrites, plagiarism and AI-text detection in a single subscription.
- Team features include style guides, brand tones, analytics and user groups; Enterprise adds SSO, SCIM and audit logs.
- Public REST APIs exist for analytics, licence management, writing score and detection.

## Grammarly limitations

- Monthly billing for Pro is $30, versus $12 per month on annual billing, so month-to-month use costs 2.5 times as much.
- Third-party tests of the AI Detector report notable false-positive rates (figures range from 14.2% to 34% across sources), so it is unreliable as proof.
- An App Store reviewer criticizes the iOS keyboard setup for pushing users to grant broad access.
- Experienced writers on forums report turning off many suggestions; advanced features are gated behind Pro.

- Suno Studio, personas and advanced stem splitting require the $30 Premier plan
