Show HN: Keeps – Mail a postcard that plays your voice

Hi everyone — I’m Clark, creator of Keeps, a way to send physical postcards that play your voice with a quick QR code scan.

WHAT IT IS Upload a photo (or pick from Unsplash), write a message, optionally add a 60 second voice note, and send a 4×6 postcard. QR code printed on the postcard links to a “digital card” that plays the audio. $5 flat, printing + postage included. No account required.

WHY I BUILT IT I love mailing postcards to my family but hate it's a hassle (finding card, buying stamp, handwriting, praying it arrives on time). I wanted to merge the charm of physical mail, the warmth of voice messages, and the efficiency of software.

HOW IT WORKS Built with Next.js, Supabase, Stripe, Resend, and Lob. QR codes link to hosted audio. Stripe handles payment. Lob prints and mails the cards. Resend emails status updates.

WHAT'S DIFFERENT - Voice note + physical card combo - Minimal editor, no sign-up friction - Transparent $5 price (everything included)

TRY IT FREE 1. Go to https://sendkeeps.com 2. Create your card 3. Use promo code SENDKEEPSFREE for a free send (first 50 people)

FEEDBACK WANTED - Editor UX - QR/digital card flow - Address autocomplete UX - Critical missing features - Interesting use cases (wedding thank yous, airbnb hosts, etc)
