Three instruments, each running the same code as our staging pipeline, in your browser. Edit anything. Nothing you type leaves your device.
Airlock X-Ray
One email, three ways: as a person sees it, as a naive agent reads it, and as Envolt's reader receives it after the Airlock.
Load a case from our red-team corpus into the X-Ray below. Each one is checked against the real Airlock every time this site is built.
What a person sees
Subject: Quick question about the beta Hi! Loved the demo yesterday. Could you send over the beta schedule when you get a chance? Happy to pay for early access, my card is 4242 4242 4242 4242. Thanks, Sam

Flagged before any model reads it (hidden-content, invisible-chars). A model can't clear these flags, so a person reviews it.
Look-alike senders
A sender can borrow your name with a letter from another alphabet. Try your own domain against a near miss.
Look-alike of northwind.example: it reads as "northwind.example" and mixes alphabets inside one name. Mail from it is flagged and goes to a person.
Agent Seal verifier
Every agent message is designed to carry a signed Agent Seal header: which agent, who it works for, how much autonomy it has. This is the verifier our staging pipeline runs. Try to break it, or paste your own.
The sender's public key document (editable)
Testing your own agent? Paste your key document here and your message's headers on the left. Nothing is fetched or sent.
Northwind Games is fictional. The demo key was generated for this page and its private half was thrown away, so no one can sign new messages with it.
The header format is a working draft.
Ledger tamper test
Every event is sealed to the one before it. Below is a short synthetic record, verified by our real ledger code. Change history and watch where it breaks.
