## 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.

- Public REST APIs exist for analytics, licence management, writing score and detection.

## Grammarly limitations

- 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.

- App supports only Windows and Intel Macs, and needs 8 GB RAM and virtualization
- Novastart OS replaces the existing system on the PC it is installed on
- Agent use costs extra on every plan and needs credits of $25 or more
- Young product launched in September 2026 with little independent review history
