<p>Demystify is a static-analysis tool for digital preservation.</p>
<p>
You can take a CSV report from DROID, or Siegfried YAML, run
it through this tool, and understand your collection better.
</p>
<p>
Demystify-lite processes everything on client-side, data isn't
shared with a server and so it can be safely used on data without
revealing your secrets to the world. This implementation is
enabled by
<a href="https://pyscript.net/" target="_blank" rel="noopener">pyscript</a>.
