Shield detects a text's personal and sensitive information and replaces it with tokens, in line with Swiss data protection law (nFADP), before you hand it to an AI. Three steps are enough: you paste the text, you check the redaction, you feed the AI's answer back in to recover the real values. Seven professional profiles are available: general, HR, doctor, psychiatrist, actuary, lawyer and CV review. Detection runs on an Infomaniak VPS in Geneva, with models hosted in Switzerland under zero retention, and the correspondence table never leaves your browser.
