- Apps and extensions for Chrome, Edge, Safari, Word, Windows, macOS, iOS and Android
Where it falls short
- Free Paraphraser has a per-run word cap; Premium unlocks the other modes
- Plagiarism Checker is not part of the free version
- Pricing page was blocked to automated access, so current plan details need a manual check
