WhoIsBringing: Real-time collaborative event checklists with zero login

Hey Product Hunt! 👋 I'm Justin, creator of WhoIsBringing.com. Whenever our group organized a weekend BBQ, a camping trip, or an office potluck, we faced the same frustrating routine: • Messy spreadsheets: People accidentally overwrite rows on mobile or struggle with permissions. • Bloated sign-up apps: Flashing banner ads, slow loading, and forcing guests to create accounts just to bring paper cups. • Group chat chaos: Messages get buried within minutes, and you inevitably end up with 6 bags of chips and no ice. We built WhoIsBringing to eliminate all that friction. 🌟 WHAT MAKES IT DIFFERENT: 1. 🚀 Zero Guest Registration: Hosts generate a checklist in 10 seconds. Guests simply open the link on mobile, enter their nickname, and tap to claim items. No passwords, no downloads. 2. ⚡ Real-Time Live Syncing: See what friends are bringing appear instantly across all devices without refreshing. 3. 🪄 AI Checklist Scanner & Generator: Have a handwritten note or an Excel file? Upload a photo or paste text, and Gemini AI auto-generates a categorized checklist. 4. 💬 1-Click WhatsApp & SMS Invites: Formats pre-written, friendly invite messages ready for group chats. 5. 🖨️ Printable Sheets with QR Codes: Perfect for fridge doors, community halls, or sports club noticeboards. 6. 🛡️ 100% Free & Ad-Free: Clean, modern UI designed for mobile speed. I’d love to hear your feedback, feature ideas, or what events you're planning next! 👉 Try creating a checklist: https://whoisbringing.com
