About Privatiser
Privatiser is a web tool that anonymizes sensitive data, such as API keys, passwords, IP addresses, and personal information, before the text is shared with AI tools. Detected values are replaced with placeholders. A redacted copy and a local mapping are produced, and the AI's reply can be pasted back to restore the original values. The homepage states that processing runs in the browser and that nothing leaves the user's machine.
Detection is pattern-based. The homepage says it may not catch every sensitive value, especially those in unusual formats or custom syntax, and that users should review the output before sharing it.
