Draft for the public Alyren docs.
Alyren extension
The extension cloaks a chat before the message leaves the browser. The model receives a linked twin. The original stays in the Alyren vault.
It covers ChatGPT, Claude, Gemini, and DeepSeek on the web. An Alyren account is required. Without a signed-in account, the extension does not cloak.
Product overview: Alyren.
Install
- Open the Alyren studio and the Extension page: alyren.veilio.fr.
- Install the package for Chrome, or the Firefox package.
- Sign in with the Alyren account in the extension popup.
- Reload the AI tab after each extension update. The popup version is the package. The chat tab keeps the previous script until it is refreshed.
A global pause sits in Settings. It is separate from the per-AI switches.
Turn an AI on or off
The Channels tab has one switch for ChatGPT, Claude, Gemini, and DeepSeek. They start on.
| Switch | What leaves the browser |
|---|---|
| On | The twin, for the message and for a supported file |
| Off | The original message and the original file, on that host only |
| Global pause | The original, on every host |
MCP and the file row are not switches. Files follow the switch of the AI you are using.
What is cloaked
The composer is cloaked before the chat request. A file dropped in the chat is cloaked before the upload.
| File | Result |
|---|---|
| Text, CSV | Personal fields replaced, file type kept |
| Word, Excel, PowerPoint | Personal fields replaced inside the document |
| PDF with real text | The same layout. Personal fields replaced in place |
Image, scan, old .doc | The upload is blocked. No OCR |
A name, an email, a phone number, an IBAN, a street, and a postal code are personal. A public organization name stays in clear.
If the cloak of a chat message fails, the message can still leave. The extension does not freeze the chat. If a supported document cannot be read, the original file does not upload.
What the model receives
You type:
Relance Jean Dupont, jean.dupont@acme.frThe model receives a twin of that person, name and email linked. Jean Dupont and jean.dupont@acme.fr stay in the Alyren vault. One cloaked field costs one credit.
The extension does not write the original back into the chat. To read it again, open the vault in the studio.
Credits and ledger
Each cloaked field debits one Alyren credit. The ledger stores the type, the count, and the channel (chatgpt, and the other chats). It does not store the value.
Pause, or a channel switched off, sends the original and does not debit a cloak.
Limits
- The extension does not see an AI you have not opened in the browser.
- It does not cloak a scanned page or a photo.
- It does not replace Veilio Core inside your applications.
- A long secret pasted as a raw API key is handled in the studio and the API, not as the main job of the chat extension.
