ChatGPT is a general-purpose assistant that has never seen your sent mail. Pranan builds a voice profile from your sent mail and applies it every time it drafts, so drafts follow your sentence rhythm, vocabulary, and tone. Pranan also reads your inbox context, calendar, and relationship history. ChatGPT does none of that by default.
