WhiteSmoke Paraphrasing Tool

LanguageTool wins for most everyday users because it offers a genuinely useful free tier, works across 30+ languages, and integrates with browsers and desktop apps. WhiteSmoke is a solid choice only if you need deep Microsoft Office integration and a built-in plagiarism checker, but its dated interface and lack of a free version make it harder to recommend for casual use.
