UndercoverGPT FAQ

How does UndercoverGPT remain undetectable?

UndercoverGPT employs advanced stealth technology that operates through proxy servers and does not make direct, identifiable calls to OpenAI's servers from your network. The cover sites are hosted independently and the chat activity is designed to blend with normal web traffic. Crucially, it avoids writing cookies, history, or cache related to ChatGPT on your device, leaving no local or network-level footprints for monitoring tools to detect.

Is it safe to use on my work or school computer?

UndercoverGPT is designed with safety and discretion as the top priority. It runs entirely in your web browser without requiring downloads or installations that could alert system administrators. However, users must always be aware of and comply with their organization's specific Acceptable Use Policies (AUP). We provide the tool for productivity, but ultimate responsibility for usage lies with the user.

Do I need a ChatGPT/OpenAI account to use it?

Yes, you typically need your own valid OpenAI API key or ChatGPT subscription credentials to authenticate and power the chat interactions within UndercoverGPT. The service itself provides the stealthy access channel and interface, but the AI model queries are processed through your personal account, ensuring you use your own allocated limits and subscriptions.

What happens if the cover site is discovered or blocked?

The team behind UndercoverGPT maintains a dynamic roster of multiple, high-quality cover sites. If one particular site were to be identified and blocked by a network filter, the service can deploy alternative sites to ensure continuous access. The mobile-first platform is built for adaptability, aiming to provide a reliable service that evolves alongside common restrictions.
