About Nonimo
Nonimo masks the personal data in what you paste into ChatGPT or Claude before it leaves: names, ID numbers, phone numbers, addresses, accounts and file references become markers like [PERSON_1].
When the answer comes back, one click on Copy with the names puts it on your clipboard with the real details, ready for your letter or email. The AI never sees them.
The masking is done by the Nonimo app on your computer. The extension hands it what you paste and nothing else: it sends nothing to our servers or to anyone.
