What this tool does
A fair coin-flip decision maker that answers Yes or No with cryptographic randomness — for the decisions that do not deserve a spreadsheet. For light decisions and games. The wording of the question does not influence the draw.
How to use the Yes or No Generator
- Enter or select your question (optional).
- Read the calculated result; change any measurement to compare alternatives.
Formula
One uniform cryptographic bit decides the answer: Yes or No, each with exactly a 50% chance, the same draw as a fair coin flip.
- question
- Your question (optional)
For light decisions and games. The wording of the question does not influence the draw.
Worked example
Sample answer: 'Should I order pizza tonight?' might come back Yes. Ask again and it might say No — each answer is a fresh 50/50 cryptographic draw, not a memory of the last one.
Inputs

Frequently asked questions
Yes. One bit from crypto.getRandomValues decides it — heads means Yes, tails means No — so over many asks the split converges on half and half, with no drift or pattern.
Each draw is independent, like flipping a coin again. If you find yourself re-asking until you get the answer you wanted, that preference is the real information — go with it.
Low-stakes deadlock-breakers: pizza or tacos, who goes first, movie A or movie B. For decisions with real consequences, the useful trick is noticing whether the answer disappoints you — not obeying the answer itself.
This tool is deliberately pure yes/no. For a three-way answer, the Magic 8 Ball's non-committal answers ('Reply hazy, try again') cover the maybe case.
No. Nothing you enter is uploaded or stored — the draw happens entirely in this browser tab and the list disappears when you close it.
