How does the yes-or-no oracle decide?

It picks Yes, No, or Maybe using your browser's cryptographically secure random number generator, so each answer is independent and unbiased.

When should I use it?

Use it to break a tie, settle a small decision quickly, or just for fun when you can't make up your mind between two simple options.

Is my question recorded?

No. Your question stays on your device — the oracle runs entirely in your browser with no network calls and nothing stored.

Are the three answers equally likely?

Yes, near enough. The tool maps a secure random byte (0–255) to one of three outcomes with modulo 3, giving each of Yes, No and Maybe roughly a one-in-three chance.

Does my question influence the answer?

No. The verdict is purely random and ignores the text you type — the question box is just there to help you frame your decision before you commit to the result.

Is this the same as flipping a coin?

It is similar but with three outcomes instead of two. A coin gives a 50/50 Yes or No, while the oracle adds a Maybe, splitting the odds roughly into thirds.

What is a cryptographically secure random number?

It is randomness from your browser's crypto.getRandomValues, designed to be unpredictable and unbiased, unlike Math.random which is only pseudo-random and not meant for security.

Yes or No Oracle

Stuck on a simple decision? Ask the Yes or No Oracle any question and get an instant, colour-coded verdict — Yes, No, or Maybe. It is a fast, private way to break a tie, settle a small choice, or just have fun when you cannot make up your mind.

How it works

Each answer is drawn with cryptographically secure randomness, not a predictable pseudo-random sequence. When you ask, the oracle requests a single random byte from the browser’s crypto.getRandomValues (a value from 0 to 255) and takes it modulo 3:

result 0 to Yes
result 1 to No
result 2 to Maybe

That gives each of the three outcomes an approximately equal one-in-three chance. The text of your question is never read — it only helps you focus the decision.

Example

Type “Should I order pizza tonight?” and press Ask the oracle. Say the random byte is 130; then 130 mod 3 = 1, so the oracle shows No in red. Ask again and a fresh byte gives an independent new verdict — past answers never affect the next.

Random value mod 3	Verdict
0	Yes
1	No
2	Maybe

Nothing you type is uploaded or stored — the oracle runs entirely in your browser with no network calls.
