Write them, seal them in digital metal, and choose the exact day they can be opened. Not even Pyadra can read them.
The vault — sealed words, opened on the day you choose
Don’t take our word for it — open the vault and see it breathe →
Four things transfer with the project — and all four already work.
The full flow is built and deployed: compose, seal, pay, deliver, unlock. Stripe live, daily delivery cron, guardian system.
The breathing 3D capsule, the entry ritual, the audio engine, the copy voice — an experience no competitor can copy-paste.
Messages are encrypted in the browser. The server stores only ciphertext and hashed keys. Not even Pyadra can read a capsule.
Audio capsules ($25), video capsules ($49) and white-label licensing for memorial, therapy and legal services — all documented, none built yet.
Some words are too early, too fragile, or too dangerous for today.
Built around one question: where do the words go that can’t be said today?
A 30-second entry of darkness and slow text. No skip button. The friction is the product.
Client-side AES encryption, three keys — sender, recipient, guardian. Sealed means sealed.
Fully functional and deployed. Waiting for its first real sale — that honesty is part of the deal.
Final terms are agreed in conversation and reviewed legally before anything closes.
“Everything online can be edited, deleted, taken back. I wanted to build the opposite — a place where sealed means sealed. Once a capsule closes, not even I can open it.”

Write the words, choose the date, seal it. Only your recipient can ever open it.

The product is fully built and deployed, but the first real paying user hasn’t arrived. You’d be buying proof of craft, not proof of demand.
Many arrive, few seal — and there are no analytics yet to know where people leave. That data is the next priority.
Stripe webhook and database are shared with Pyadra today. Full independence is documented and takes 15–25 hours.
The 30-second ritual filters out impatient users by design. That limits volume — and creates the value.
Yes — the complete flow is live: compose, seal, pay $9, scheduled delivery, unlock with a key. Try it yourself before asking anyone anything.
No. Messages are encrypted in your browser before they ever reach a server. We store only ciphertext and hashed keys — zero-knowledge by design.
The code, the brand, the ceremonial experience, the encryption engine and the delivery system — plus a documented roadmap to full independence.
It launched recently and the first sale is still pending. We say it plainly because everything on Pyadra is said plainly.
Seal one today, or take the whole vault with you.
