## Supported Platforms
## How It Works
1. **Paste**: You paste text containing PII or secrets into the chat input.
-2. **Mask**: The extension sends text to your local PasteGuard server for masking.
-3. **Chat**: Masked text is inserted into the chat. The provider sees placeholders such as `[[PERSON_1]]` and `[[EMAIL_ADDRESS_1]]`.
-4. **Copy**: When you copy a supported AI response, placeholders are replaced with the original values.
+2. **Mask**: The extension sends text to your local PasteGuard server's `/api/mask` endpoint.
+3. **Chat**: PasteGuard masks secrets first, then PII, and returns masked text with local placeholder context. The provider sees placeholders such as `[[PERSON_1]]` and `[[EMAIL_ADDRESS_1]]`.
+4. **Copy**: When you copy a supported AI response, placeholders are replaced with the original values using the local context.
Placeholder numbering stays consistent across messages in the same conversation. Streamed responses are highlighted in real time.
