Our take
Pick Grammarly if students and knowledge workers who want inline grammar in Gmail, Docs, and the browser. Pick Sudowrite if novelists and students who want a fiction-specific toolbar and will burn monthly credits. Skip Grammarly if people who need a paraphraser with named modes (QuillBot) or a rewrite box that leads with “humanize” (Wordtune). Skip Sudowrite if people who need inline grammar in the browser
