both honestly. the drafts cut the writing but the assignment and progress tracking is what saved my sanity as a PM
As a proposal manager you feel it on coordination as much as writing. You assign questions and sections, set reviewers, and track progress in one dashboard, and reviewers approve from Slack so you are not sending reminders all day. The Full Response Analyzer does a final pass across the whole document for contradictions, missing requirements and tone, which is normally the PM stitching everything together by hand. That pass alone changed my deadline days.
coming from loopio the coordination felt similar tbh, the big diff was the drafts arriving already written so there was less to chase
