Hi everyone — I’m Clark, creator of Keeps, a way to send physical postcards that play your voice when the recipient scans the QR code. 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 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. My intent was not to replace handwritten postcards (I still love those), but rather offer another way to make a physical note feel personal. 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 OUT Use coupon code PH50 at checkout for 50% off your first card Happy to share details or answer questions about this fun side project! Appreciate any feedback.
