About Anonyma.chat: protect your data in ChatGPT & Claude.

Anonyma.chat is a Chrome extension built for users who value privacy and data protection when interacting with ChatGPT. In a world where AI-driven conversations are becoming increasingly central to professional and personal communication, ensuring that sensitive information remains confidential is critical. Anonyma.chat allows users to effortlessly anonymize prompts and responses directly within the ChatGPT interface, without relying on external servers or risking personal data exposure. With a sleek and intuitive design, Anonyma.chat seamlessly integrates into ChatGPT’s interface, providing powerful anonymization tools while maintaining a smooth and uninterrupted user experience. Whether you are a lawyer, journalist, corporate executive, researcher, or simply a privacy-conscious individual, Anonyma.chat offers a fast, effective, and secure way to protect your conversations. Main Features One-Click Anonymization With Anonyma.chat, protecting your sensitive data is as easy as clicking a button. Instantly cipher words, names, or phrases in both your input prompts and ChatGPT’s replies, ensuring that confidential information stays private during the conversation. Custom Word Management Users can specify particular words or expressions that should always be anonymized automatically. The extension allows for full control over custom mappings, enabling you to adapt the anonymization behavior to your specific needs or ongoing projects. Mapping Overview Anonyma.chat includes a live mapping panel where users can view, manage, and adjust all active ciphered words. The mappings table provides clarity and control over the anonymization process, helping ensure that nothing important is missed. Reset and Undo Mistakes happen, but Anonyma.chat offers a safety net. With a simple reset feature and a 20-second undo window, users can clear all mappings and restore previous settings if needed, without losing valuable configuration work. Smart Auto-Suggest with Named-Entity Recognition (NER) The extension intelligently identifies personal names, places, organizations, and other sensitive entities, offering automatic suggestions for anonymization. This powerful feature streamlines the protection process, especially in fast-paced or information-heavy conversations. Theme Synchronization Anonyma.chat is built to blend perfectly with your environment. It automatically detects your browser or system theme (light or dark mode) and adjusts its interface accordingly. Manual theme switching is also available for those who prefer custom settings. Copy Clean Text Anonyma.chat allows users to copy the clean, deciphered version of ChatGPT's responses with a single click. This feature is especially useful for exporting conversations, sharing them securely, or archiving discussions without exposing private data.
