Give it a clear prompt and it produces clean, capable prose on almost any subject. The friction is the workflow: another tab, paste the thread, describe the tone, copy the answer back, fix what doesn’t fit.
Opens inside the compose window, already sees the thread you are replying to, and gives you a voice and dials for tone instead of a paragraph describing it. The draft lands where it lives.
For essays, code, brainstorming or research, ChatGPT is excellent and PersonaDraft is not trying to replace it. If the goal is a well-toned reply sent from your inbox without leaving Gmail, that is the exact job PersonaDraft is built for.
