Secure browser-local randomizer

Yes or No Generator

Generate a simple Yes or No result for an ordinary low-stakes choice. Each answer has the same chance and stays in this browser tab.

Choose options and generate a result.

How it works

A secure browser random value is mapped to one of two outcomes with rejection sampling. The result is generated locally and is not based on clicks, timing, animation, or personal information.

Example

One generation returns Yes or No. A batch of 20 reports the exact number of Yes and No outcomes without implying advice or prediction.

Limits and appropriate use

Generate 1 to 1,000 answers. Batch mode shows Yes and No totals plus a bounded recent sample. Do not use this tool for medical, legal, financial, safety-critical, gambling, or regulated decisions.

Randomness and privacy

Production uses Web Crypto and never falls back to Math.random. Automated tests inject deterministic values only inside the test harness; there is no public URL, query parameter, or page control for replacing the random source.
