Press Decide for a Yes or No.
How the yes or no generator works
When you press Decide the tool draws one secure random number and maps it to an answer. With two answers, Yes and No each have a probability of exactly 1 in 2. With Maybe turned on, each of the three answers has a 1 in 3 chance. The question you type is only shown back to you above the answer: it does not influence the result, and it is not stored or sent anywhere.
The result is as fair as a coin toss, but it also avoids the physical quirks of a real coin. A coin flip says heads or tails; this page says the words you actually need. It does not know anything about your question, so treat it as a tie-breaker, not an oracle.
Using it to make a decision
- Best used when you are torn. Press Decide and notice your reaction. If you feel disappointed by the answer, that tells you what you wanted.
- Low-stakes choices. Order in or cook? Go now or later? Text first or wait? Chance is a fine way to settle choices where either option is acceptable.
- Games and classrooms. Truth-or-dare style prompts, true-or-false drills, “does this sentence follow the rule?” quizzes.
- Not for serious decisions. Do not use a random answer for medical, legal, financial or safety choices. Get advice from a qualified person.
Streaks are normal
Each press is independent. The chance of the same answer twice in a row is 1 in 2, three in a row 1 in 4, and five in a row 1 in 16 (6.25%). Because streaks like that are expected, a run of identical answers does not mean the generator is stuck or rigged. The tally under the answer counts this visit only and resets when you close the page.
The answer comes from crypto.getRandomValues(), the browser’s cryptographically secure generator, not Math.random().
Frequently asked questions
Is the yes or no answer really 50/50?
Yes. The tool draws a secure random number and maps it to Yes or No, so each has exactly a 1 in 2 chance. With Maybe turned on, each of the three answers has a 1 in 3 chance.
Does my question change the answer?
No. The question is only displayed back to you. The answer is chosen by chance alone, and the text is not stored or sent anywhere.
Can I get a Maybe answer?
Yes. Tick "Include Maybe as a third answer" and each of Yes, No and Maybe becomes equally likely.
Why did I get the same answer several times in a row?
Each press is independent, so streaks happen. Getting the same answer five times in a row has a 1 in 16 chance with two answers. It does not mean the tool is broken.
Is this the same as flipping a coin?
The odds are the same, but this page gives you the words Yes and No instead of heads and tails. For a coin animation and statistics use the coin flip tool.
Should I use it for important decisions?
No. It is a tie-breaker for low-stakes choices. For medical, legal, financial or safety decisions, get advice from a qualified person.

Checked
The answer is one rejection-sampled draw from crypto.getRandomValues(), which MDN describes as returning cryptographically strong random values. The 50/50 and 1-in-3 splits and the answer mapping are unit-tested; streak probabilities are simple powers of 1/2. Everything runs in your browser. Nothing you enter or generate is sent anywhere or stored.
Scope
A light-hearted tie-breaker, not advice. Do not use a random answer for medical, legal, financial or safety decisions.
