What should you remove from an AI prompt?
Remove information that is unnecessary for the answer. Common examples include full names, personal email addresses, phone numbers, IP addresses, account identifiers, API keys, private links and cryptocurrency wallet addresses.
Use placeholders when context still matters
Replacing “Mia Chen” with “the customer” often preserves meaning better than deleting the whole sentence. UCLLL uses visible masking so you can review exactly where information changed.
Never paste secrets just to test a cleaner
If an API key or password may be real, revoke or rotate it. A masking tool reduces accidental disclosure; it does not make an already exposed secret safe again.
Why local processing matters
Text entered into UCLLL is processed in your browser. There is no account, upload, database or analytics tracker, so the cleaner does not need a copy of the text it protects.
