About this tool
The random letter sequence generator spits out a string of random letters of any length — from a quick 3-letter code to a 100-character jumble. Set the length, choose the case, and add handy options like ‘no repeats’ or ‘at least one vowel’.
It is ideal for inventing nicknames and codes, making practice strings for typing or spelling drills, generating game tiles, or just grabbing a pronounceable-ish jumble. One tap, copy, done.
Frequently asked questions
How is this different from a single random letter?
A single-letter picker gives you one letter; this tool produces a whole sequence of letters at once — great for codes, game tiles, nicknames, CAPTCHAs-style strings or memory drills.
Can I avoid repeated letters?
Yes — tick ‘No repeats’ and every letter in the sequence is unique (up to 26, since there are 26 letters in the English alphabet).
Is each letter equally likely?
Yes. Letters are drawn with your browser’s secure random generator, so A through Z each have the same chance unless you switch on an option like ‘at least one vowel’.
Can I copy the result?
Absolutely — press Copy and the sequence is on your clipboard, ready to paste anywhere.
