How it works

A notary for predictions.

You seal a claim before the outcome is known. Presaid anchors it on an independently verifiable public record, and reality settles it — hits, misses and silence alike. Two short films: why it exists, and how you use it.

Why it exists

Anyone can say they called it after the fact. A claim sealed before the outcome — and anchored where it can’t be moved or backdated — is the difference between a memory and a proof.

Everyone remembers their hits.
Presaid remembers everything.

Independently verifiable · no account needed · presaid.io

Anyone can say they called it — after it already happened.

So you seal it first — a claim locked before the outcome is known.

Committed and cryptographically sealed.

Anchored on a public record — it can’t be moved or backdated.

When reality answers, every call is scored — hits and misses alike.

A prediction, notarized live — sealed before the outcome, anchored where it can’t be rewritten.

How it works

Three steps: write what you think will happen, seal it in one tap, and hand anyone a certificate they can verify without trusting us.
