How Our Tools Work

All of our tools run entirely in your browser using JavaScript. This means no data is ever sent to any server — your files, code, and content never leave your device. This architecture ensures maximum privacy and security while eliminating upload wait times. Whether you're working with sensitive API keys, proprietary code, or personal documents, your data stays completely private.

• Browser-Based — Secure, fast, and works even with limited connectivity. No server round-trips means instant results.
• Open and Transparent — We are clear about how our tools work and what minimal analytics we collect.
