Sealed: hide private data from AI chats

Hide CNICs, phone numbers, IBANs, emails and API keys before you paste into an AI chat, then restore them in the reply.

Paste work into any AI chat without giving away CNICs, phone numbers, bank details or API keys. Sealed swaps private details for labels like [PERSON_1] and [CNIC_1] before you share it. When the reply arrives, it restores the real values. It all happens on your device. There is no server, and the extension cannot connect to the internet. HOW IT WORKS 1. Click the Sealed icon to open the side panel and paste your text. 2. Private details are highlighted by type. Click a highlight to keep it visible, or select any other text to hide it too. 3. Click Hide & copy (or press Ctrl/⌘ + Enter) and paste into your AI chat. 4. Paste the AI's reply into the Restore tab. The labels turn back into the real values, ready to copy. WHAT IT CATCHES • CNICs, with or without dashes. It can tell a CNIC from an order or invoice number. • Pakistani mobile numbers in any format: 0300-1234567, +92 300 1234567, 0092… (every format of the same number gets the same label) • Pakistani IBANs, verified with the IBAN checksum • Email addresses • Debit and credit cards, verified with the Luhn check • API keys and access tokens from common developer services. Long random-looking strings are flagged for you to check. • Passport numbers and NTNs, when the text mentions them BUILT FOR HOW PAKISTAN WRITES Works in English, Roman Urdu ("Saad ko invoice bhej do") and Urdu script. Add the people, clients and projects you mention often under Always hide, with every spelling (Muhammad / Mohammad), and they get the same label every time. RESTORE THAT FORGIVES THE AI AI chats often rewrite labels, for example turning [PERSON_1] into <person_1> or Person 1. Sealed still restores them, and it never mixes up the 1st and the 10th. Any label it doesn't recognise is marked in red so you can spot it. PRIVATE BY DESIGN • No account, no sign-up, no analytics, no ads • The extension is blocked from making any network requests • Your names and hidden values are kept in memory only. They are wiped when Chrome closes, or right away when you click Clear. • Runs in the side panel only. It never reads or changes the websites you visit. Free, with no limits. Note: Sealed finds people and company names only after you add them under Always hide. It is a helper, not a guarantee, so look over the highlights before you send.
