Random Fact Generator

Generate a real fact from science, history, space, and more, to learn something new, settle a debate, or find your next piece of trivia.

About this generator

This generator draws from 250 real trivia facts across nine categories -- Science & Nature, History, Space & Astronomy, Human Body & Health, Geography & Places, Food & Drink, Technology & Inventions, Animals & Wildlife, and Weird & Surprising.

Every result here is drawn using crypto.getRandomValues() -- the Web Crypto API's cryptographically secure randomness -- instead of Math.random(), so it's genuinely unpredictable, not just statistically random. Learn more.

What people use it for

Trivia hosts use it to pull a quick fact for a round without prep work. Teachers use it for a classroom bell-ringer, and it's also a solid daily "learn something new" habit or a way to settle a debate with a genuine fact.

How it works

Generate draws one fact at random from the full 250-entry pool using the site's cryptographically secure randomness, guaranteed not to repeat whatever result is currently showing in single-result mode. Filtering by category narrows the pool before drawing.

Common questions

Are these facts actually true?

Yes -- all 250 are genuine, verified facts, not invented trivia.

Can I filter by category, like only Space & Astronomy?

Yes -- use the filter button to pick one or more of the nine categories. Generate will then only draw from facts in the categories you've selected.

Will it show me the same fact twice in a row?

Not in single-result mode -- each new roll is guaranteed to differ from the one currently on screen.

Does it include weird or unusual facts, not just standard trivia?

Yes -- Weird & Surprising is one of the nine categories.
