Our take
Pick Grammarly if students and knowledge workers who want inline grammar in Gmail, Docs, and the browser. Pick Writefull if researchers writing in Word or Overleaf who will pay Premium when the free quota runs out. Skip Grammarly if people who need a paraphraser with named modes (QuillBot) or a rewrite box that leads with “humanize” (Wordtune).
