Verify a prediction

Recompute the SHA-256 hash of any prediction we've published. The hash math runs in your browser — we never receive what you compute. If you arrived via a prediction <code>?id=</code> link, your browser also fetches that prediction's canonical fields from our public dataset to populate the form; the hash computation itself never leaves your machine. You can also do it yourself, fully offline, with the snippets below.
