Get started
austenite is a stack of probabilistic engineering tools. The fastest path: pick a flow, run it, scan the confidence badges, stamp the result. The agent tabs your decisions back into a single transcript you can audit.
Open the console
Pick a flow on the left. Inputs → Run → Result.
Check the confidence badge
GREEN = stamp-eligible. YELLOW = review before stamping. RED = blocked unless overridden with justification.
(Optional) Connect your AI key
The agent uses your key, called directly from your browser. austenite.org never sees it.
Stamp the verdict
Hash-chained PDF with replay manifest + RFC 3161 timestamp + verbatim cited clauses.
