Overview

Protects against sensitive data leaks when uploading files and clipboard

Nolex protects your sensitive data when working with AI platforms. HOW IT WORKS Nolex runs entirely in your browser. It scans text inputs, clipboard paste events, and file uploads for sensitive information — and warns you before the data gets sent to an AI service. WHAT IT DETECTS Built-in detection patterns cover: • AI and cloud service API keys • Cloud and DevOps credentials (access keys, tokens, webhooks) • Database connection strings • Email addresses, phone numbers, credit card numbers • JWT tokens, SSH/RSA private keys You can also create your own custom regex patterns with the built-in editor. SMART CONSTRUCTOR Don't know regex? Use the Smart Constructor to build detection rules visually — pick a data type, choose format options, and Nolex generates the pattern for you. KEY FEATURES • Real-time scanning of text inputs and paste events • File upload interception with content analysis • 30+ built-in patterns for API keys, credentials, and personal data • Custom regex rules with import/export support • Smart Constructor for building rules without coding • Works on any website — not just AI platforms • Toggle individual rules on/off PRIVACY FIRST • 100% local — your data never leaves your browser • Zero telemetry, zero analytics, zero tracking • No accounts required, no sign-up • No network requests made by the extension • All settings stored locally on your device • Open source: https://github.com/Defyzzz/nolex PERMISSIONS EXPLAINED • "Read and change all your data on all websites" — needed to inject the detection script on any page where you might interact with AI. Nolex only reads text inputs to scan for sensitive data. It does not modify page content or collect browsing data. Nolex is free and open source. Protect your privacy — install Nolex.
