About randomizer tools

Tool Matic's randomizers cover the everyday picks and rolls you reach for - drawing a name, rolling a number, spinning a wheel - without installing anything or leaving your browser.

Whether you are running a classroom raffle, picking a winner from a comment thread, choosing where to eat tonight, or generating values for a test, these tools are built to be quick, fair, and effortless.

Every tool in this category runs entirely in your browser. Random values are produced with the Web Crypto API, the same cryptographically strong source modern browsers use for security primitives.

What you get

  • Runs in your browser All logic runs locally. Names and lists you paste in never leave your device.
  • Cryptographically strong Values come from the Web Crypto API, not Math.random().
  • Works offline After first load, every tool works without a connection.
  • Instant results Open a tool and start immediately.

Frequently asked questions

Do these online randomizer tools send my data to a server?
No - every randomizer tool on Tool Matic runs in your browser. There is no usage limit. Open any tool and start using it immediately.
Are the results really random?
Tool Matic randomizers draw values from the Web Crypto API (window.crypto.getRandomValues), the cryptographically strong random source built into modern browsers. This is the same source used for generating session tokens and cryptographic keys, and it is far stronger than Math.random(). Truly unpredictable randomness still comes from physical sources, but for picking names, rolling dice, or running raffles, Web Crypto is more than fair.
Do you store the names or lists I paste in?
No. All Tool Matic randomizers run entirely in your browser. The names, items, or ranges you enter are never transmitted to Tool Matic servers. You can verify this yourself by opening your browser's DevTools Network tab - you will see zero outbound requests carrying your data.
Do these tools work offline?
An internet connection is required for the first load. Once the page is loaded, the randomizers continue to work because they execute entirely in your browser using JavaScript. Offline-first support via service-worker caching is planned for a future release.
Can I use Tool Matic randomizers for raffles, giveaways, or live streams?
Yes. The Wheel of Names is designed for classroom picks, livestream giveaways, and team-meeting raffles, and the Random Number Generator works well for ticket-based draws. For high-stakes or regulated draws (lotteries, compliance audits), use a tool that can produce a verifiable, signed result and keep an external record of inputs and outputs.
What is the difference between a random number generator and a wheel picker?
A Random Number Generator returns one or more values from a numeric range - good for dice rolls, coin flips, ticket draws, and generating test data. A Wheel of Names takes a custom list of items and animates a spin to one of them - good for naming a winner, deciding what to do, or making the reveal visible to a group.
