Obscura intercepts your prompts before sending, automatically masks emails, names, numbers and confidential data, then restores everything in the response — seamlessly.

How it works
The extension acts before and after each request. You see nothing — except the green border confirming protection.
As soon as you click Send, the extension intercepts the prompt. A secure API request replaces each sensitive piece of data with a tag — [EMAIL_1], [NAME_1], [PHONE_1] — then injects the masked text into the AI with the mention [SHIELD_PROCESSED].
jean.dupont@acme.fr[EMAIL_1]While the AI responds in streaming, a MutationObserver with debounce analyzes each block. Our API restores the real data on screen — even if the AI didn't repeat the exact tag. The message is locked in data-shield-state="done".
[EMAIL_1]jean.dupont@acme.frAI response, restored: "Hello, I've prepared the summary for jean.dupont@acme.fr regarding the file of M. Bernard. »
Green border: your prompt was encrypted, processed and restored locally.
