AI Privacy Shield

Locally detect and block sensitive data in AI chat text and uploaded TXT, DOCX, XLSX, and PDF files before sending.

AI Privacy Shield helps you keep phones, emails, ID numbers, API keys, and other sensitive details out of AI conversations. It watches the chat box on popular AI websites and also reviews files you are about to upload, so sensitive content can be caught before it leaves your browser. When something is detected, you get a clear confirmation panel. You can sanitize with one click, skip specific items, or add them to a whitelist. Placeholders stay stable in the conversation, and replies can be restored locally on your device. Everything runs in your browser. We do not collect prompts, files, or detected values. Free for personal use. 中文说明 AI Privacy Shield（AI隐私盾）帮助你避免把手机号、邮箱、证件号、API密钥等敏感信息误发给AI工具。 它会在常用AI网站的对话框中检查内容，并在你上传文件前完成本地检查，尽量在信息离开浏览器之前拦截风险。 发现敏感内容后，会弹出确认面板。你可以一键脱敏发送、跳过个别项，或加入白名单。会话中使用稳定占位符，AI回复里的占位符也可在本机还原。 全部检测与处理均在浏览器本地完成。我们不会收集对话内容、文件或检测到的敏感值。 个人使用免费。
