About the Random Letter Generator
This tool picks random letters from A to Z using the browser's secure random source. Choose how many you want, whether they arrive in upper or lower case, and whether they are spaced out or run together as a single block of characters.
Every one of the twenty-six letters is equally likely on each draw, and the draws are independent, so the same letter can appear twice in a row. That is expected behaviour, not a fault, though it surprises people who assume a random sequence should look evenly spread. Sampling the alphabet evenly also means vowels turn up far less often than they do in English, where E alone accounts for roughly one letter in eight, which is why a run of random letters reads as unpronounceable. If you need each letter used once and once only, list A to Z and put it through Shuffle Lines instead.
It fits word games such as Scattergories and Boggle-style rounds, alphabet practice in a classroom, picking a random starting letter for a naming exercise, and labelling test cases in an unpredictable order. For random digits instead, the Random Number Generator; for mixed letters and digits at a fixed length, the Random String Generator; to switch the output to title case or another form, the Case Converter.
