Jev for marketing, sales & social

Marketing and social work is full of judgment calls: is this hook strong, is this post worth reading, is this lead a fit. These projects hand those calls to Jev and keep the writing to people or other models.

What Jev decides: Score a draft or a lead, pick the strongest option, or filter a feed.
