Check a Song Seal record

Paste a record, add the file it describes, and this tells you whether they match — and what it could not check.

Your file never leaves this page. It is read and hashed in your browser. Nothing is uploaded, and there is no server to upload to.

This runs the same verify.mjs the record host publishes, unchanged. It is a convenience, not an independent check — it is served by people who have an interest in your record verifying. The stronger path owes us nothing: sha256sum yourfile and compare to the digest printed on the record.
