InfiniUm Shield is a browser extension designed to protect sensitive information when users interact with AI platforms such as ChatGPT, Claude, and Gemini. By automatically masking personal data, passwords, API keys, and other confidential details in prompts before they are sent, the extension aims to provide a privacy layer between the user and AI services without altering the user's workflow.
The extension operates entirely client-side, ensuring that all scanning and masking take place within the user's browser and that no data is sent to external servers. InfiniUm Shield scans prompts for emails, passwords, API keys, phone numbers, and 19 other types of sensitive data, replacing real values with safe tokens before the information leaves the browser. When AI responses echo these tokens, the extension swaps them back to the original values, maintaining the readability and usefulness of responses. Users can also add custom words and phrases to be masked, such as project codenames or internal product names. The extension supports automatic operation with no required configuration, per-site toggling, and provides masking statistics and history.
InfiniUm Shield is intended for a broad audience, including professionals in legal, healthcare, development, business, human resources, and security roles who use AI tools in their daily work. It enables these users to benefit from AI assistance while safeguarding client names, case details, confidential documents, patient data, company information, and infrastructure details.
The extension is available for Chrome and can be installed without creating an account. A free version offers full protection for all supported AI tools, while a Pro plan, available for a monthly fee, adds features such as team collaboration, rule syncing across devices, shared dictionaries, audit logs, advanced detection patterns, unlimited custom rules, and priority support. InfiniUm Shield positions itself as an AI privacy protection solution, providing a trust layer for users concerned about sharing sensitive data with AI platforms.
InfiniUm Shield sits in PulseGate's Security & compliance platforms category. It focuses on preventing accidental sharing of sensitive personal data with AI chatbots by masking information before it leaves the browser.
