Three ways to carve

Open — plaintext on The Tower, public on your dashboard. First is free, then $2.

Sealed — encrypted in your browser with a key only you hold. We see only ciphertext. $5 (launching soon).

Time Capsule — hidden until a date you choose. Auto-opens then; we email you. $10 (launching soon).

How It Works

1. Sign in with your email — we’ll send a one-time link.

2. Pick a tier from above, type your idea. Sealed and Time Capsule encrypt in your browser before we ever see it.

3. Every hour, entries are batched and anchored to Bitcoin via OpenTimestamps.

4. Pull a shareable proof receipt — free if you have the SHA-256 hash or own the entry; $5 if you only have the original text. Cryptographic, independently verifiable, court-grade.
