PromptVeil, a last-second privacy firewall for AI chats

Field notes

PromptVeil’s described intervention happens at the point where text is submitted: Return and paste events are scanned locally, then the user can send a redacted version or stop the message. The examples show reversible tokens for items ranging from AWS access keys and PostgreSQL connection strings to Indian PAN numbers and forwarded financial statements. The page lists coverage across major browsers, desktop apps, and several AI services, but the extract does not confirm availability of the underlying macOS utility.
