How do I make a random decision online when I can’t decide?

Open AnyTool Decision Maker, choose a mode and press Decide (or the spacebar): Yes/No gives a clean two-way answer (add an optional “Maybe”), Pick an option draws one winner from your own list, Magic 8-Ball replies with one of the 20 classic answers, and This or That picks between two choices. Every answer is decided by your browser’s crypto-secure randomness for a true, unbiased result — you can weight options with “*N”, and a recent-decisions history is kept. Nothing is uploaded.

  • Four modes: Yes/No (+optional Maybe), Pick an option, Magic 8-Ball, This or That
  • Crypto-random pick (Web Crypto, no modulo bias) — never Math.random
  • Weighted options: add “*N” or list an item more than once for bigger odds
  • Short reveal animation, copy the answer, recent-decisions history
  • 100% in your browser — your question, options and results are never uploaded

What is

Random Decision Maker

A random decision maker is a tool that resolves a choice by drawing an answer at random rather than by reasoning — for example returning Yes or No, picking one option from a list, or giving a Magic 8-Ball reply. A fair one uses a uniform random source so each candidate answer is equally likely (or proportional to an assigned weight); the draws are independent, so past results never change the next, and the tool has no knowledge of the situation and no predictive power.

Frequently Asked Questions

Yes. AnyTool decides each answer with crypto-secure randomness (Web Crypto) using rejection sampling, so every option is exactly equally likely with no bias.

AnyTool Decision Maker draws every answer from the browser’s Web Crypto API (crypto.getRandomValues) using rejection sampling, so there is no modulo bias and each candidate — Yes vs No, the items in your list, or the 20 Magic 8-Ball answers — is exactly equally likely. It never uses the predictable Math.random. The answer is chosen first and the short reveal animation only visualizes it, so what you see is always the real, fair result.

Yes. In Pick-an-option mode, add “*N” after an option (e.g. “Stay in *3”) or list it more than once to give it N× the odds.

In the Pick-an-option mode you type one option per line, and you can weight any option by adding “*N” at the end — “Beach *3” gives that option three times the chance of an unweighted option — or simply by listing it more than once. The tool sums all the weights and draws a crypto-fair integer across that total, so the probability of each option is its weight divided by the sum of all weights. Without weights, every option is equally likely.

It replies to a yes-or-no question with one of the 20 classic Magic 8-Ball answers — 10 affirmative, 5 non-committal and 5 negative — picked at random.

The Magic 8-Ball mode mimics the classic fortune-teller toy: you ask a yes-or-no question and shake the ball to get one of the traditional 20 answers, which are split into 10 affirmative (e.g. “It is certain”, “Without a doubt”), 5 non-committal (e.g. “Reply hazy, try again”, “Ask again later”) and 5 negative (e.g. “My reply is no”, “Very doubtful”). Each answer is drawn with equal probability using crypto-secure randomness. It is for entertainment only and has no predictive power.

No. It is a fun, unbiased helper with no opinion or prediction power — use it to break ties, not for important, financial, medical or legal choices.

A random decision maker knows nothing about your situation and cannot predict outcomes; it simply flips a fair coin in disguise. It is great for breaking a tie, settling a friendly argument, or beating decision paralysis when the options are genuinely close and you would be happy with either. It is not appropriate for important, financial, medical, legal or safety decisions, which deserve real thought and qualified advice. Everything runs locally and nothing is uploaded.

Detailed Explanation

Methodology

How the Decision Maker Chooses an Answer

AnyTool Decision Maker decides every answer in the browser using the Web Crypto API, and it chooses the result first — the reveal animation only visualizes it. The candidate pool depends on the mode: Yes/No draws from {Yes, No} (or {Yes, No, Maybe} when Maybe is enabled), This or That draws from your two labels, Magic 8-Ball draws from the classic 20 answers, and Pick-an-option draws from your typed list. The draw uses securePick / secureRandomInt, which sample from crypto.getRandomValues with rejection sampling — values outside an even multiple of the pool size are discarded — so there is no modulo bias and every candidate is exactly equally likely. Math.random is never used.

  • Answer drawn from crypto.getRandomValues (CSPRNG) via securePick / secureRandomInt
  • Rejection sampling removes modulo bias — every candidate is exactly equally likely
  • Result is chosen first; the reveal animation only displays it
  • Four modes: Yes/No (+optional Maybe), Pick an option, Magic 8-Ball, This or That
  • All randomness runs client-side — no server round-trip
Use Cases

Weighted Options and the Magic 8-Ball

In Pick-an-option mode, each line is one option and an optional trailing “*N” sets a weight (1–999); listing an option more than once has the same effect. The tool sums all weights and draws a crypto-fair integer across the total, walking the cumulative weights, so the probability of an option is its weight divided by the sum of all weights — “Beach *3” against an unweighted “Mountains” is a 3:1 split. The Magic 8-Ball mode returns one of the traditional 20 answers, balanced as 10 affirmative, 5 non-committal and 5 negative, each with equal probability. Every mode keeps a recent-decisions history, and any answer can be copied.

  • Weights via “*N” (1–999) or repeated lines; P(option) = weight / total weight
  • Equal odds for every option when no weights are given
  • Magic 8-Ball: 20 classic answers (10 affirmative, 5 non-committal, 5 negative)
  • Yes/No supports an optional third “Maybe” outcome
  • Recent-decisions history and copy-to-clipboard for every answer
Privacy & Security

Honesty, Independence and Privacy

A random decision maker has no knowledge of the situation and no predictive power — it is a fair coin in disguise, useful for breaking ties, settling friendly arguments or beating decision paralysis when the options are genuinely close, but not for important, financial, medical, legal or safety choices. Each decision is an independent event, so a run of “Yes” answers never makes “No” more likely (the gambler’s fallacy), and the Magic 8-Ball mode is for entertainment only. Because everything runs in the browser, no question, option or result is sent to a server, logged or stored — closing the tab discards it, and the page works offline once cached.

  • No opinion or prediction power — a fair random helper, not advice
  • Not for important, financial, medical, legal or safety decisions
  • Each decision is independent — no outcome is ever “due” (gambler’s fallacy)
  • No uploads, logging or storage — question, options and results stay in the browser
  • Works offline after first load (PWA-cached); free, no account, no tracking
