Frequently Asked Questions
Quick answers to common questions about using this tool.
Does the Random Letter Generator upload anything? +
No. Letter generation runs in your browser during normal use. The generated letters are not sent to PotatoTools.
Can I generate vowels or consonants only? +
Yes. Use the Letter Type controls to choose all letters, vowels only, or consonants only.
How does No-Repeat mode work? +
No-Repeat mode removes generated base letters from the current round. It never resets automatically, so use Reset Round when you want to start over.
Can I use a custom letter set? +
Yes. Enable Custom Letter Set and enter English A-Z letters. Duplicate letters are removed.
Does Mixed Case affect no-repeat tracking? +
No. Mixed Case changes the display only. No-Repeat tracking uses the base uppercase letter.
