Draft for the public Alyren docs.
Alyren
Alyren is a Veilio product. It cloaks sensitive fields before they reach ChatGPT, Claude, Cursor, or any LLM agent. Core still tokenizes PII inside your apps. Alyren covers the prompt side. Separate accounts, Alyren credits (no standalone Alyren subscription).
Your teams keep talking to an AI. The model receives a linked twin, not your customer. The original stays in the Alyren vault.
What Alyren does
Alyren replaces a personal field with a twin the model can read. The same person keeps the same twin: the name and the email of Jean stay linked. The model drafts with Pavel Sartre. The vault still holds Jean Dupont.
The ledger records the field type, the count, and the channel. It does not record the original value.
One cloaked field costs one Alyren credit. Alyren has no subscription of its own. Credit packs, and a later option on a Veilio plan, are the commercial forms. This page does not set a price.
Who it is for
| Reader | Job |
|---|---|
| Someone pasting a client, an IBAN, or an ID into a chat | Use the extension. The chat keeps working. |
| A developer calling an AI from code | Call POST /v1/cloak with an alr_live_ key. |
| A team whose agent drafts, then sends a mail, an SMS, or a CRM update | Put the proxy in the agent process. The client receives the real person. |
| A company that will not send originals to the Alyren cloud | Run the same Alyren app on your network, and point the agent at that URL. |
The buyer is usually the same committee as Veilio Core: DPO, CISO, CTO. The account is not the same account.
Alyren and Veilio Core
| Veilio Core | Alyren | |
|---|---|---|
| Job | Tokenize personal data inside your systems | Cloak what leaves toward an AI |
| What the other system stores | A token tok_ | A readable twin |
| Vault | Veilio | Alyren |
| Account | Veilio | Alyren, separate |
| Identity link | None. No shared login, no shared organization id | None |
A Veilio plan can later include Alyren as an option. That does not merge the accounts, and it does not make Alyren credits unlimited.
What each side sees
| Place | Content |
|---|---|
| The person, in the chat or the studio | The original, when they ask the vault for it |
| The model | The twin only |
| The client who receives a mail or a CRM write | The original, after the agent proxy restores it |
| Alyren ledger | Type, count, channel |
| Alyren vault | The link between the original and the twin |
Public organization names stay in clear. Comité Départemental de la Savoie is not a person. A street and a postal code are.
Where to start
| Need | Page |
|---|---|

What Alyren does not do
- It does not tokenize your application database. That is Veilio Core.
- It does not read a scanned PDF or a photo. There is no OCR.
- It does not put the original back into the chat page. The original stays in the vault.
- It does not give the model a way to restore the original.
