ReplyJoy auto-drafts your Gmail replies in your voice. It learns your tone from past emails and pulls context from your calendar, so drafts are accurate — not generic AI fluff. What's different: • Tone-matched to you, learned from your sent mail • Calendar-aware (meetings, attendees, availability) • One-click setup — no prompt engineering • Open source: self-host free, or use the hosted version My wife (nonprofit worker) cut her daily email time in half during beta.

Hey Product Hunt — Derek here. I built ReplyJoy because my wife works at a nonprofit and told me she spends ~30% of her day on email. I wanted to give her time back. The hard part wasn't generating replies — any LLM can do that. The hard part was making drafts that actually sound like her, with the right context: who's the recipient, what meeting is this about, what did we last discuss. So ReplyJoy: - Reads your past emails to learn your tone - Pulls calendar context (meetings, attendees, timing) - Drops drafts straight into Gmail — edit or send After beta testing with my wife, she cut her email time in half. It's also open source if you'd rather self-host: github.com/ConsulInc/replyjoy-oss Would love your feedback — especially on tone accuracy. What would make this your daily driver?
