Prelude is an AI-powered date-planning assistant with a keyboard extension for modern chats. It helps you draft replies and concrete invites without bouncing between apps. 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. AI message drafting Generate reply ideas, follow-ups, and invite drafts you can refine before you send. Keyboard extension Keep Prelude close to the conversation so you can draft inside your keyboard instead of bouncing between apps. Voice Studio Adjust the tone so the draft feels like you: warmer, calmer, more direct, or more playful. Partner Cards Keep track of the details that matter so the next message has continuity instead of guesswork. Plain-language trust See key product choices in clearer language, including permissions and billing context, so you can decide with confidence. Prelude is built for busy daters who want respectful momentum, not gimmicks. It is designed to help you sound confident, tactful, and still like yourself.
