NetraShield - Privacy-First Browser Agent

Local-first browser agent that masks personal data before cloud reasoning.

NetraShield is a browser assistant designed to help you complete everyday web tasks safely and efficiently. Instead of manually switching between pages, searching for information, filling forms, and navigating complex websites, you can describe what you want in plain language. NetraShield observes the active page, creates a plan, performs permitted browser actions, and verifies the result. Why install NetraShield? Save time: Automate repetitive browsing, navigation, searching, and form-filling tasks. Protect sensitive information: Personal data detected on a page is masked locally before screenshots or page context are sent for cloud reasoning. Stay in control: Sensitive actions require confirmation before execution. Use your existing sessions: NetraShield works inside your current Chrome profile, so it can assist on websites where you are already signed in. See what is happening: Follow the agent’s progress, proposed actions, privacy protections, and results from the extension interface. Reduce unsafe automation: Actions are evaluated by a deterministic policy layer and verified against a fresh page observation. Block suspicious instructions: The extension detects and neutralizes potential prompt-injection content found on web pages. NetraShield can help with tasks such as: Finding and summarizing information on the current page Navigating websites using natural-language instructions Searching websites and comparing visible results Filling forms with user approval Reading supported documents and webpages Performing multi-step browser workflows Masking sensitive information before AI-assisted reasoning NetraShield is built for users who want the convenience of browser automation without giving up visibility, privacy, or control.
