Same in-place rewriting workflow — the bubble next to your selection, the card, the one-click insert. The difference is control and price: Grammarly Pro is $12/month on their models; ParaphrasePro is $2.99/month on ours, or free forever with your own API key.

Grammarly's dedicated grammar engine is deeper: tone detection, plagiarism checks, style guides for teams, and native apps beyond the browser. If your main job is proofreading long documents at a company that already pays for it — keep Grammarly.
If what you actually do all day is rewrite — emails, posts, messages — you get the same in-place workflow plus rewrite controls Grammarly doesn't have (variants, synonyms with freeze, custom modes, 20-language translate), at a quarter of the price. And because you can bring any API key, you choose the AI model and can pay $0/month to us.
