capsl — Digital Time Capsules

Seal a message for your future self, a friend, or the public. Unlocks at a chosen date — or only with a password. End-to-end encrypted with VetKeys IBE on the Internet Computer.

What you can seal

A letter to your future self — locked to your next birthday, anniversary, or a decade from now.
A public prediction — publish a call and let the world watch it unlock. Receipts, timestamped.
A time-locked gift — a voice note for their 18th, a song for your anniversary. Landing exactly when it should.

How it works

Every capsule is encrypted in your browser using Identity-Based Encryption (VetKeys) and sealed on the Internet Computer. Nobody — not even the canister — sees your content until the unlock condition is met: a timestamp, a recipient Internet Identity, or a password you share.
