Compare AI Privacy Tools

Three approaches, three different results

Every tool on this page promises the same thing: your personal data does not reach the model. What differs is what each one puts in its place — and that is what decides whether the AI can still help you.

• Generic tokens. ChatWall masks PII using anonymization tokens before prompts reach AI chatbots. Supports multiple providers and offers both local processing and on-premise Docker deployment for enterprise. MyYaad vs ChatWall →
• [REDACTED] placeholders. Caviard detects and redacts PII using local NLP and regex, replacing sensitive data with [REDACTED] placeholders. Supports 100+ PII entity types with a focus on ChatGPT and DeepSeek. MyYaad vs Caviard →
• Detect, then alert or redact. Redact.tools detects PII in prompts and offers alert, redact, and unmask actions. Focused on ChatGPT with 100% local processing and a free-forever model. MyYaad vs Redact.tools →

Realistic shadows. MyYaad replaces your real data with realistic shadow values — fake names, addresses and numbers that keep AI responses coherent and useful — and then de-shadows the reply, putting your real values back on your screen. Generic tokens like [NAME_1] and [REDACTED] placeholders can confuse AI models and degrade response quality; neither ChatWall, Caviard nor Redact.tools restores your real values in the response the way MyYaad does. MyYaad also gives each provider different shadows for the same real data, so if one provider is breached, shadows from another cannot be correlated back to you. All of it runs locally, against a persistent on-device vault.
