# What is HackerGPT?

Canonical: https://hackergpt.org/about/

HackerGPT is an OSINT and CTF-solving toolkit designed for anyone interested in cybersecurity. It brings together the essential tools needed to conduct thorough security assessments while offering a hands-on, learn-by-doing experience. Whether you're looking to build your knowledge or sharpen your penetration testing skills, HackerGPT provides a practical way to learn and grow.

## Who runs HackerGPT?

HackerGPT is run by HackerGPT Inc., a 501(c)(3) nonprofit. The people working on it are on [the team page](https://hackergpt.org/team/), and [the contact page](https://hackergpt.org/contact/) is how to reach them.

## How do hackergpt.org and hackergpt.app relate?

They are the same HackerGPT, at different addresses for different jobs:

- **hackergpt.org** is this site, where you read and learn: articles, the glossary, the documentation and what each feature does.
- **[hackergpt.app](https://hackergpt.app)** is the product. You sign up and use the agent there.
- **cybergym.hackergpt.app** is [CyberGym](https://hackergpt.org/features/cybergym/), a deliberately vulnerable target we run for practice.

## Is this the same as other projects called HackerGPT?

No. Other websites, code repositories and chat tools use the name HackerGPT too. They are separate projects: we do not run them and they do not speak for us, so what you read about "HackerGPT" in a search result or an AI answer may be about one of them.

The address settles it. Our sites are the three above, and these are our accounts:

- [X](https://x.com/HackerGPT_Lite)
- [YouTube](https://www.youtube.com/@HackerGPT-app)
- [TikTok](https://www.tiktok.com/@hackergpt)
- [Facebook](https://www.facebook.com/profile.php?id=61579008377991)
- [GitHub](https://github.com/hacker-gpt)

A site or account that is not on this page is not ours.

## What can I test with HackerGPT?

Only what you are allowed to test:

- your own website or app
- [CyberGym](https://hackergpt.org/features/cybergym/), which exists so that people can practice on it
- a target whose owner has given you written permission
- HackTheBox CTF challenges
- Bug Bounties on HackerOne, BugCrowd, etc.

Never point it at someone else's site without that permission. [The rules of legal hacking](https://hackergpt.org/legal-hacking/) explain who can give it and what it has to say.
