Compare AI Privacy Tools

Three approaches, three different results

Every tool on this page aims at the same thing: less of your personal data reaching 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 stand-ins. MyYaad swaps the details you save and the ones it detects automatically for realistic stand-ins — 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 stand-ins for the same real detail, so stand-ins seen by different providers do not match each other. The swap runs on your device, against a persistent on-device vault.
