The animated scene
Follow the request all the way to the model.
Go through the scene at your own pace or replay a step: in this fictional example, three detected values give way to placeholders before sending.
Fictional data; the model shown does not reflect the catalog of your plan.
Step by step
The request keeps its meaning. The detected values are replaced.
Drafting a payment reminder doesn’t require sending your client’s bank details to the model. In this fictional example, four values give way to placeholders, then go back in place in the answer.
Original message: Draft a reminder for invoice F-2026-118 issued to Atelier Brunet, 15 days overdue. Include the IBAN FR76 3000 6000 0112 3456 789 and the SIRET 812 345 678 00044. Version sent to the model: Draft a reminder for invoice FACTURE_01 issued to ENTREPRISE_01, 15 days overdue. Include the IBAN IBAN_01 and the SIRET SIRET_01.
Answer in your workspaceRestored answer: Hello, according to our records, invoice F-2026-118 issued to Atelier Brunet is still outstanding. You can pay by bank transfer to the IBAN FR76 3000 6000 0112 3456 789.

Stay in control
Control starts before you send.
Detection can miss things. Sensitive information can also be inferred from context, even when some fields are masked.
Before you send
- Leave out details your request does not need.
- Check what you are allowed to share.
- Avoid secrets, access credentials and unnecessary documents.
- Review the answer before you use it in your work.
The real values only come back in the answer you read: the model itself only saw the placeholders.
