What “random” means here (simple formula)

This tool is a random fact picker. It has curated fact lists (by category), and each time you generate a result it chooses one fact from the appropriate list. The core idea is the standard random-index formula:

RandomIndex = ⌊ Math.random() × N ⌋

Where N is the number of facts available in your selected category. Math.random() returns a number between 0 (inclusive) and 1 (exclusive). Multiplying by N scales it to the list size, and flooring it converts it to a valid array index from 0 to N − 1.

The “Randomness level” slider doesn’t change math (random is already random), but it changes selection behavior: at higher levels, the picker is more likely to choose from the “spicier” portion of each category list (facts that are a bit more surprising, unusual, or counterintuitive — still safe, still PG).

How we estimate “virality” (lightweight scoring)

A fun tool feels better when it nudges you toward content people actually share. So every fact gets a playful Share Score from 0–100 based on:

• Novelty signals: words like “first”, “only”, “never”, “largest”, “tiny”, “invisible”.
• Rhythm: short punchy sentences tend to share better.
• Curiosity hooks: “did you know”, “surprisingly”, “scientists found”.
• Category boost: animals, space, and weird-safe often get extra reactions.

This is not science. It’s a content UX helper so you can quickly pick the facts that get “wait what??” replies.

Sample runs (so you know what to expect)

Example 1 (Mixed + Short & punchy): You generate a one-liner fact, then tap Copy and drop it into a group chat.

Example 2 (Space + Mind-blown): You get a longer “mind-blown” fact. You screenshot the result card and post to stories.

Example 3 (Animals + Wholesome): You generate a wholesome animal fact and save it as a favorite for later.

Since the selection is random, your results will be different each time — that’s the point.

How to use it like an Omni-level tool

Omni-style calculators are useful because they are fast, clear, and have enough depth that people trust the page. Here’s the simple workflow:

1. Pick a category (or stay on Mixed for variety).
2. Generate 5–10 facts.
3. Keep the best 1–2 by pressing Save and ★ Favorite.
4. Copy/share a favorite. Then try a different vibe to see how it changes.

Over time, your “Saved facts” list becomes a mini personal stash for captions, party prompts, icebreakers, and “fun learning” moments.

Frequently Asked Questions

• Is the fact content accurate?

  These facts are curated and simplified for quick reading. Treat them as “fun learning.” If you’re using a fact for something important (school, work, publication), verify it from a primary source.

• Why do I get repeats?

  Random selection can repeat — especially if a category has a smaller list. Try a different category, switch the vibe, or increase randomness level.

• Where are my saved facts stored?

  Saved/favorited facts are stored in localStorage on this device and browser only. Clearing site data or using a new device will remove them.

• Can I share directly to social apps?

  Yes. The Share button uses the browser’s share sheet when available (mobile), otherwise it copies a share-ready text you can paste anywhere.

• Is this an “AI fact generator”?

  No. This page is intentionally non-AI for speed, safety, and consistency. It’s a curated random picker with helpful share tools.
