Is the random letter generator free?
Yes. It is completely free to use, with no signup, no account, and no paywall.
Do I need to install anything?
No. It runs in any modern browser on desktop or mobile, with nothing to download and nothing to configure.
Does it stay local?
Yes. Generation happens entirely in your browser, and nothing is sent to a server.
Why do I keep getting difficult letters like Q and Z?
Because every letter has exactly the same one-in-26 chance, and English does not work that way. In ordinary English text, E accounts for around 12.7% of letters and Z for around 0.07%, a difference of more than a hundredfold. A uniform generator hands you Z as readily as E, which is mathematically correct and makes for a frustrating word game. This is exactly why Scattergories uses a 20-sided die that omits Q, U, V, X, Y, and Z, and why Scrabble's tile bag contains twelve Es and one Z.
Can the same letter come up twice?
Yes, because each draw is independent. With 26 letters, requesting 10 gives you a better than even chance of at least one duplicate, which follows the same logic as the birthday paradox. If you need a set of distinct letters, generate extra and remove the repeats, or shuffle the alphabet and take from the front.
How random is the draw?
It uses crypto.getRandomValues, the browser's cryptographically secure generator, with rejection sampling to remove the small bias a naive modulo operation introduces. Without that correction, the earlier letters of the alphabet would come up very slightly more often than the later ones, because 26 does not divide evenly into the range of a 32-bit number. The effect would be tiny and it is straightforward to eliminate, so it is eliminated.
Can I get lowercase letters or only vowels?
No. The output is uppercase A to Z, and there is no filter for vowels or consonants and no lowercase mode. If you need a lowercase letter, convert the output yourself. If you need a vowel, the practical approach is to draw letters until one appears, though at five vowels in 26 that will take a few tries.
Is the letter chosen on a server?
No. It is drawn in your browser and never transmitted, so the result is not visible to anyone else and the tool works offline.
