A random fact generator selects short statements from a curated list so teachers, hosts, and creators can skip manual list-making. It is designed for prompts and activities—not as a peer-reviewed encyclopedia, citation library, or fact-checking service.
This Muxgen tool runs in your browser: set fact-count (default 3), pick a Fact category, toggle Allow duplicate facts, generate numbered fact cards, and copy. No account and no server upload for your picks.
Three simple steps from category filter to copy-ready fact lists.
Enter fact-count (default 3), then pick a Fact category chip from 7 options including All categories.
Toggle Allow duplicate facts for repeats up to 50, or turn it off for unique-only batches capped by the category pool (10–60).
Click Generate fact, review numbered fact cards, then Copy to clipboard for slides, chat, or worksheets.
Every control in the random fact generator component.
Number input min 1 — max 50 with duplicates on, or maxBatchForFactSettings when duplicates off. Default 3.
7 toggle buttons from FACT_CATEGORY_FILTER_OPTIONS — default All categories.
Checked by default — enables repeated facts and raises max count to 50. Unchecked uses a used Set for unique picks within the pool.
Live pool.length from getFactPool — updates when category changes; disables generate at zero.
Polite region reports category updates, duplicate mode changes, count clamping, and generateFacts status strings after each run.
Primary button — plural label when count > 1; disabled when pool.length === 0.
Right panel shows emerald cards with bold index prefix per fact, or empty state "Configure options and click generate" with light-bulb emoji.
Ghost button — formatFactCopyList export with numbered lines; Copied! feedback for two seconds.
