What are you working on?
Start with the task: a document to share, a prompt to send, or a flow of records to prepare. These products share an engine, but their processing, restoration and availability differ. Each page explains the details.
In the tools you use
Something a person opens: a document, a spreadsheet, a chat window.
PROD-01
Cover
Cover is the Synthaveil add-in for Microsoft Office. Review identifying details in Word or Excel and replace them with stand-ins before sharing a copy.
Available for private evaluation in Word and Excel. Request an evaluation build. The films illustrate the workflow.
PROD-02
Alias
Alias is the Synthaveil browser extension. Add names to your watchlist, swap them for stand-ins in a supported chat composer, and review the result before you press send.
Available for private evaluation. We confirm the supported chat sites with you during setup.
In the systems you run
Something that runs without anyone watching: a workflow, a service, a scheduled job.
PROD-03
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.
Available for private evaluation. Request an evaluation build.
PROD-04
Legend
Legend is the Synthaveil engine and the SDK for your own applications. Run it as a library, sidecar or container in your environment, and choose a treatment for each field.
Available to early-access organisations under agreement. Contact us to discuss the SDK and deployment requirements.
PROD-05
Station
Station is the Synthaveil application your organisation runs for itself. Your team configures a data source, marks the identifying columns and saves a template for repeat jobs.
Available to early-access organisations. We set up the deployment alongside your team and confirm your sources and connectors first.
Where your data goes
Processing and restoration are different questions. Use this overview to choose which product details to check.
| Product | Processing | Restoration information |
|---|---|---|
| Cover | Word and Excel add-ins. We confirm the processing endpoint with you during evaluation. | Local mapping in Word; workbook-associated mapping protected by a passphrase in Excel. |
| Alias | Private mode sends matched names to the API, not the whole message. | Keep the browser mapping protected. It is needed for the local reply view and cannot be recovered if you lose the passphrase. |
| Courier | The n8n node sends selected fields to its configured Synthaveil endpoint. | Rejoin results to your records, or restore real values inside your own n8n environment. |
| Legend | Self-hosted library, sidecar or container processes original values inside your environment. | Synthaveil holds no table to reverse it. Plan any local rejoin separately. |
| Station | Customer-run container. Confirm source connectors and the configured processing path at setup. | Your team manages the deployment, access and keys. Confirm recovery for the selected flow. |
Status as at 8 September 2026. Access is by invitation to early-access organisations. Every product on this register is a data tokenisation control: configure protection levels to match your own legal and regulatory obligations. You hold the key, so your data remains personal data in your hands; the recipient gets stand-ins with no key or mapping to link them back.
