Courier
Courier is the Synthaveil node for n8n. Place it before the step that sends records to an AI tool, and choose which fields to replace.
For people building automations for their own team or for clients.

COU-01
One node, dropped in front of the AI step
Map each field to how it should be treated, and the records that leave the node carry stand-ins instead of people.
Map each field to its treatment. A name can become another name; a field left unmapped passes through unchanged. Check the node output before connecting the next step, including any free text.
What stays your decision
You choose the fields, and you check the output before the next step runs.
COU-02
Keep the structure your workflow needs
Consistent replacements can support grouping within the same key and policy scope.
A workflow can group records by the replacement customer identifier while leaving an amount unchanged. Format preservation helps downstream validation, but does not prove that every calculation has the same result. Test the queries and relationships your workflow uses.
What stays your decision
Consistency also permits linkage inside that scope. Choose how long it should last.
COU-03
You can show what happened
Usage and quota are visible inside the workflow itself, so the privacy owner can see what was replaced and when.
Usage and quota information appear with the node’s output. Use execution history to check the steps that ran, with access and retention set for the data that history contains.
What stays your decision
Run history covers this workflow. It cannot prove that every other route used the same controls.
Courier can rejoin results to your records, or restore real values inside your own n8n environment using information only you hold. Synthaveil cannot reverse stand-ins for you.
