LLMs are deterministic engines. They can't roll a fair die or pick a winner without bias. We built the solution that injects cryptographically secure randomness directly into your ChatGPT chats.

Computers are deterministic machines. LLMs like ChatGPT predict the next most likely token based on training data. They fail the two core requirements of randomness.
We tested hundreds of "random" requests. ChatGPT overwhelmingly chooses numbers like 47, 81, or 82. This isn't luck—it's statistical bias from human text data.
For a draw to be fair, every participant needs an exactly equal probability. LLMs "feel" which answer fits best, destroying the uniformity required for giveaways.
If a system is predictable, it can be gamed. In our tests, we could even trick ChatGPT into picking a specific "random" winner by hiding instructions in the input list.
* Standard LLMs statistically favor certain numbers (like 42, 47, 7) due to training data frequency. Our app uses cryptographically secure entropy.
We don't let the AI guess. Our app connects ChatGPT to a source of true physical randomness—atmospheric noise, radioactive decay, or secure OS entropy.
The app fetches data from certified randomness providers like Real Random, bypassing the LLM's neural network logic entirely for the decision phase.

Item 42 of 500 • SHA-256 Verified
Integrated directly into your workflow.
Set any range (e.g., 1-1,000,000). Perfect for cryptographic keys, lottery simulations, or statistical sampling.
Ask ChatGPT to generate a list (e.g., "Top 10 sci-fi movies") and let Randomizer pick one fairly.
Paste a list of entrants. The app parses them and selects a winner using unbiased entropy. No rigging possible.

This connector does NOT work on mobile devices (iOS/Android apps). You must use the web version of ChatGPT (chatgpt.com) in a desktop browser.
Follow these 5 simple steps to connect our Randomizer app to your ChatGPT in under 3 minutes.
This unlocks the ability to create and test custom connectors.



Once Developer Mode is active, a "Create" option will appear.



ChatGPT will show a pop-up asking for permission to use the custom connector.
This is normal and required every time you use a new connector.
Click Confirm.
💡 Note: If the permission request does not appear, open a new chat and try sending the prompt again.

The response may take 10–30 seconds to appear.
This delay is caused by OpenAI's backend routing, not our app. Be patient.
Once loaded, you'll see a visual widget with the random number and a dice emoji.
