Grammarly fixes your commas. ChatGPT rewrites the whole thing. Neither does what a real editor does: read your draft and tell you what's actually working and what isn't. Margin is that editor. Margin knows your voice, leaves notes in the margin of your draft, you pick how deep the feedback goes, from quick polish to hard critique, and nothing changes unless you accept it. It learns your voice and how you want it to edit as you write, so the notes fit you, not a template. You keep the pen.
