Random letter generator
One letter, or a short run, from the set you pick.
Vowels are A, E, I, O, and U. Y counts as a consonant, so the odds stay fixed.

About this page
Tap Generate for one letter, or for a short run of them. The random letter generator uses the 26 letters of the English alphabet and nothing else. Vowels are A, E, I, O, and U. Every other letter, including Y, is a consonant, so the odds are simple enough to say out loud before anyone taps. Any letter means one draw from 26, which makes a vowel a 5-in-26 outcome. It is not a coin flip of vowel versus consonant. Uppercase and lowercase are applied after the letter is chosen, so the case control does not change which letter can appear. Mixed case flips a fair coin for each letter you already drew. No repeats keeps each letter once, treating A and a as the same letter, and it refuses a count longer than the set you picked. Vowels can give you five unique letters and no more. The alphabet can give you 26. When the box is unchecked, a run may show the same letter twice, because each position is its own draw. The page loads with no letter selected. There is no account, and each tap is a new draw in this browser.

Questions
Is each letter in the alphabet equally likely?
Yes, when the Letters menu says Any letter. One tap with a count of one is a single index into A through Z. The draw uses crypto.getRandomValues in your browser, then rejection sampling so the leftover remainder of a 32-bit value cannot favor the low end. ChanceKit does not claim atmospheric noise, hardware entropy you can audit from this page, or a casino-style provably fair setup. Read the methodology before you use a result for anything that matters. The page does not prefer letters that start more English words, and it does not avoid rare letters such as Q or Z. A classroom tally of a few dozen draws will not come out even. That clump is what a fair alphabet looks like in a short session.
Are vowels as likely as consonants?
Only if you picked one of those sets on purpose. Vowels are five letters, so under Any letter a vowel shows up 5 times in 26, about 19 percent. Consonants are the other 21, about 81 percent. If you set Letters to Vowels, every result is A, E, I, O, or U, each at 1 in 5, and a consonant cannot appear. Consonants work the same way in the other direction. The menu changes the pool before the draw. It does not reweight a full alphabet after the fact.
Why is Y counted as a consonant?
Because a letter generator has to publish one rule. Y is a vowel in 'gym' and a consonant in 'yes', and a tool that guessed from a missing word would be inventing a spelling. This page puts Y with the consonants so the vowel set stays at five and the consonant set stays at 21. The line under the controls says so, and the methodology page repeats it. If your game treats Y as a vowel, draw from Any letter and ignore the draws you do not want, or agree that rule before you tap.
What does no repeats actually change?
With the box unchecked, each letter is an independent draw, so two A's in a row can happen. With the box checked, the page shuffles the pool and takes the first letters, which means every subset of that size is equally likely and the same letter cannot appear twice. A and a still count as one letter. Case is chosen afterward. Five unique vowels are the whole vowel set, in a random order. Six unique vowels are impossible, and the page will say that instead of quietly allowing a repeat. The longest unique alphabet draw is 26 letters.
Does uppercase change which letter I get?
No. The letter is chosen in lowercase, and the case is a second, separate step. Uppercase maps every result to capitals. Lowercase leaves it. Mixed case tosses a fair coin per letter, so K and k are equally likely once K has been selected, and that coin does not make K more likely than Q. A count of one in mixed case is still one letter from the pool, shown in one case. The readout spaces the letters so a run does not look like a word.
When should I use a word or a number instead?
Use this page when the outcome is a letter: a row of the alphabet, a vowel for a phonics game, an initial. Use the random word generator when you want a lemma from the English list, with a part of speech or a category and a length. Use the number page when you want an integer, including 1 through 26 if the letters were only a disguise for a count. A string of random letters is a poor password. It is also a poor stand-in for a word, because most letter strings are not words. There is no signup. Copy puts the letters and this page's address on the clipboard after you generate.
