Fair randomness

The wheel, number generator, coin and dice all use your browser's cryptographically secure random number generator with unbiased sampling. Every outcome has exactly the same chance, and results can't be predicted from earlier ones.

Great for classrooms

  • Spin the Wheel to choose who answers next.
  • Coin Flip and Dice Roller for hands-on probability lessons.
  • Online Timer for activities and tests, shown full screen on a projector.
  • Typing Speed Test for keyboarding practice.

Private by design

Nothing you type or generate is sent to a server. The notepad stores notes only in your own browser, so they stay on your device.

Frequently asked questions

Are the random results fair?

Yes. The wheel, random number generator, coin flip and dice use your browser's cryptographically secure random number generator (crypto.getRandomValues) with unbiased sampling, so every outcome is equally likely.

Do these tools work offline or on my phone?

They run entirely in your browser and work on phones, tablets and computers. Once a page has loaded, most tools keep working without a connection.

Is anything I type saved on your servers?

No. The notepad saves notes only in your own browser's local storage, and nothing else you enter is stored.
