I built an extension that hides your personal information from AI (github.com)

A developer has introduced OpenCloak, a Chrome extension designed to enhance user privacy by masking personal information in AI prompts before they are sent. The extension operates locally on the user's GPU via WebGPU technology, ensuring that no sensitive data leaves the device. When a user composes a prompt in AI platforms like ChatGPT or Claude, OpenCloak identifies personal details and swaps them with believable fakes. Users can choose whether to retain real values or generate different substitutes, maintaining the coherency of the conversation while safeguarding their identity. This development is significant for the AI/ML community as it addresses escalating privacy concerns surrounding AI interactions. By employing an on-device detector trained on synthesized privacy data, OpenCloak empowers users to interact with AI without fear of their personal information being exposed or used. The extension's various technical capabilities, including replacing text in real-time and ensuring the consistent substitution of specific terms, showcase its innovative approach to privacy-preserving AI usage. OpenCloak represents a step forward in creating user-friendly tools that advocate for data protection while still enabling the rich conversational capabilities of AI.
