Instead of sitting on "we should hang sometime," open Date Ops, choose the moment, set the vibe and budget, and let AI draft a concrete invite you can actually send. The goal is not louder lines or generic AI output. The goal is to move a real conversation forward with more clarity and less overthinking. What you can do with Prelude Date Ops Choose intent, vibe, budget, and timing to turn a vague chat into a plan-rich next step.
