Quick randomness test

Enter entries and weights, run repeated draws, and compare observed results with expected probability.

Results use the browser cryptographic random source.

When this tool makes sense

Choose the random workflow that matches the job. PickForMe is strongest when the decision is repeatable, explainable, and small enough to move on quickly.

Fair, private, and built for repeat use

PickForMe behaves more like a lightweight decision workspace than a one-off animation. It works well for classrooms, raffles, teams, and everyday decisions that happen again and again.

Crypto random source

Results use the browser crypto random source where available instead of relying on plain Math.random.

Lists stay local

Reusable lists and history are stored in this browser. No account is required for the core workflow.

Weights and no-repeat rounds

Use text like Pizza | 3 for preferences, or enable elimination mode when results should not repeat.

Share and embed

Copy tool links, share configured lists, or embed a picker inside another page.

Copy-ready list templates

Start from the version closest to your job, then replace the entries with the real options. One line equals one option; entries with | 2 get extra chances.

Frequently asked questions

Does a randomness test prove every future result?

No. It is a practical simulation that shows whether repeated draws trend toward the expected distribution. Individual random draws can still repeat or look uneven.

Can I test weighted entries?

Yes. Use the same plain-text weight syntax as the picker, such as Alex | 3, then compare the observed share with the expected weighted share.
