NIST Beacon Quantum Entropy · Free for Every Seeker

Quantum Coin Toss

The oldest decision-making tool there is, backed by a real quantum measurement instead of a coin's own imperfect physics. No AI reading, no interpretation — just a real Heads or Tails, straight from a live pulse of the NIST Randomness Beacon. Good for yes-or-no questions and quick decisions you'd rather not overthink.

How It Works

Before you toss — decide what Heads means and what Tails means for your question. That's the part that has to happen first, honestly, in your own head. The toss itself just answers it.

The NIST Randomness Beacon publishes a brand new measurement of the quantum field every 60 seconds — that's also why the toss has a 60-second cooldown. It's not an artificial limit; it's simply how often a genuinely new measurement exists to toss with.
