| You give up | — | You set up an AI key (Gemini has a free tier) or a local model; no underlining as you type. | Flags problems but doesn't fix grammar for you; AI rewrites need the paid Plus plan. | No grammar or spelling fixes or tone rewrites; it only highlights weak phrasing. | No phone keyboard, so you can't check text on mobile. |
