You've built something valuable.
Custom GPTs that solve real problems. Refined prompts you've tested for weeks. Curated knowledge bases. Proprietary methodologies embedded in AI.
They can copy your custom instructions, knowledge base content, prompts, and proprietary methodologies—in seconds.
Not because you did anything wrong. Because OpenAI doesn't offer built-in protection for custom GPT instructions.
That's exactly what we built to fix.

Yes. This system works with any custom GPT you create in OpenAI's platform. Whether you built it yesterday or months ago, you can add password protection in 5 minutes.
Use the system on every GPT you create as long as you subscribe. Unlimited GPTs. Create 5 GPTs or 500 GPTs—same price.
No. The authentication happens before the GPT loads, so there's zero impact on speed or functionality once users log in. Your GPT runs at full speed—no lag, no delays.
Users must provide the correct username and password to access your GPT. The authentication is built into the GPT's core instructions. Without valid credentials, the GPT won't respond to queries or reveal its instructions.
Is it 100% unbreakable? No security system is. But it creates a significant barrier that protects against casual copying and unauthorized access—which is what 99% of GPT creators need.
