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
