Signato Studio

Let's build your first wall.

Five screens, in business language. At the end, you see a forbidden send
blocked for real, with your own names.

Everything runs on this machine. No data leaves here: the page talks only to the local Signato engine.

Who receives information from your operation?

Lawyers, banks, advisors, family members, accountants. One at a time.

Person's name

Other ways they appear in text (nickname, email), separated by commas

Or reuse a contacts export:

Which subjects have an owner?

Each sensitive subject becomes a list of trigger phrases that identify it in text.

Subject name

Trigger phrases, separated by commas (specific ones avoid false alarms)

What must each person NOT know?

Tap the subjects to block. HARD stops the send; SOFT lets it through with a warning.

Check before saving.

Each wall, read as a sentence.

Your wall is standing.

Matrix and scenarios saved. Now prove it: test a real send.

Simulated send (edit freely and test again)

Next steps (in the terminal, in the output folder):

signato check --matrix matrix.yaml 'text from a real send' signato test --matrix matrix.yaml --scenarios scenarios.yaml signato attest --matrix matrix.yaml --log attestations.jsonl
