How random number generators work.

Browser-based generators use built-in browser features to produce random or pseudo-random values. Those values can be turned into numbers, letters, cards, names, colors, or other outputs.

Random vs procedural

Some tools pick a random item from a list. Others assemble results from multiple parts, such as prefixes and suffixes. Simulators like cards and dice use random values to mimic real-world draws or rolls.

Limits matter

Everyday Generator uses limits so large simulations do not freeze a browser or mobile device.

Local statistics

When a tool tracks history or charts, it stores totals locally in your browser so you can see patterns over time.
