Cachet: Cards & Love Letters

Some words are worth keeping.

Cachet turns a message into a letter — written on real-feeling paper, sealed in wax, and opened with a press. It's the greeting card app for people who'd rather send something meaningful than another text.

WRITE · SEAL · SEND — under a minute

1. WRITE. A quiet blank page. No templates shouting "Happy Birthday," no AI writing it for you. Choose your paper tone, your ink color, and typed or handwritten script. The words are yours.

2. SEAL. The part everyone screenshots. Press and hold to pour molten wax, then press your mark into it — with a thunk and a haptic that lands. Pick your wax color and your seal mark. Once it's sealed, it's sealed: no takebacks.

3. SEND. You get a private link. Share it in any chat app — messages, WhatsApp, Instagram, wherever they already are. They break the seal and read your letter right in the browser. No app to install, no account, no sign-up on their side.

THEY BREAK THE SEAL
Your recipient holds to crack the wax, just like you held to pour it. The letter opens for them alone. You'll see when it's delivered and when it's opened — framed as ritual, not surveillance.

A LETTER FOR EVERY OCCASION
Birthday cards. Thank you notes. Love letters. Anniversary letters. Valentine's cards. Christmas and holiday greetings. New Year wishes. Congratulations, get well soon, sorry, good luck, I miss you. And the biggest one of all — just because, with no occasion at all.

Group an occasion together and write everyone their own letter. No shipping, no stamps, no waiting.

YOUR LEDGER
Every letter you send settles into your ledger, kept as one thread per person. Two years of letters with your mum lives here. Reread anytime — it's an archive, not a feed.

THE COLLECTION
Wax colors, seal marks, paper tones, and ready-made sealing sets — a birthday candle pressed in teal wax, a heart in pink for whatever this is, a single fir for the cold months. New artist drops land every month and are gone when the month ends.

WHAT CACHET DOESN'T DO
No feed. No stories. No streaks, badges, or confetti. No AI-written messages. No credits or per-card pricing. No account required — you can write your first letter within seconds of opening the app.

CACHET CLUB
Sending letters is free, always and unlimited. The Club unlocks the full collection: every wax color, every mark, every paper, monthly artist drops, personal marks, and no ads. Available monthly, yearly, or as a one-time lifetime purchase.

PRIVATE BY DEFAULT
Letters aren't posted anywhere. Each one opens through its own private link that only the person you send it to receives. No public profiles, no browsing other people's letters.

ALSO INSIDE
· 14 languages — English, Spanish, French, German, Italian, Portuguese, Japanese, Korean, Chinese (Simplified & Traditional), Russian, Turkish, Thai, Vietnamese
· Light and dark themes, built for the desk at midnight
· Handwritten or typed script for the letter body
· Your monogram, embossed into every seal

Stop sending "hbd 🎉". Write something real, seal it properly, and let them break the wax.

Cachet — break the seal.
