On-device visual & DOM privacy runtime for AI browser agents. Detects and redacts sensitive data locally before cloud reasoning. Hido — Zero-Trust AI Guard Hido is an on-device privacy layer for AI-powered browser agents. It helps protect sensitive information on webpages before browser context is shared with AI services. How Hido works • Detects sensitive information locally in webpage content and forms • Identifies PII such as email addresses, passwords, payment information and other sensitive data • Redacts, masks or tokenizes sensitive information before transmission • Applies a zero-trust egress check to inspect sanitized context before it leaves the browser • Provides local privacy controls and protected-value handling • Includes an Action Guard to help prevent unsafe AI-driven browser actions • Works as a browser privacy layer without requiring raw webpage data to be stored by Hido Privacy by design Hido is designed to keep sensitive processing as close to the user’s device as possible. Its privacy pipeline combines webpage perception, local PII detection, sanitization and outbound-context validation before AI processing. Built for AI-powered browsing Hido is designed for workflows where AI agents need webpage context to perform tasks while minimizing unnecessary exposure of sensitive information. Key capabilities ✓ Local PII detection ✓ On-device sanitization ✓ Zero-Trust Egress ✓ Protected local values ✓ AI Action Guard ✓ Browser-based privacy controls Hido AI sees what it needs. Nothing more.
