NICH: GPT Anonymizer

NICH: GPT Anonymizer is a privacy-first tool that anonymizes sensitive text before sending prompts to AI models, while still preserving context for effective tool usage. It performs deanonymization on AI responses when needed, allowing users to restore original data. The processing is device-based, offline-capable, and never uploads data to the cloud.

How It Works

1. Anonymise your prompts in one click. Before sending prompts to AI tools, the text is masked to remove names, company details, contact information, and other sensitive data while keeping context intact.
2. Deanonymise responses when needed. Restore the original data from AI responses with a single click.
3. Operate offline and on-device. All processing can occur without an internet connection; no data is stored in the cloud.
4. No cloud storage. Your data stays on your device at all times.
