Create a card in under a minute, share it by QR, NFC, link or messaging app, scan paper cards, and let an AI note-taker transcribe and summarise meetings. Flutter mobile app, Next.js public card pages, Supabase backend, with all features free.

What it does

  • QR, NFC and link sharing with two-way contact exchange
  • Paper card scanning
  • AI meeting recording, transcripts and summaries
  • Card analytics and contact manager
  • 24 design mockups and a documented design system

Writing the PRD and architecture first, then building against them without re-deciding anything, is what made a five-week ship possible.
