Random Letter Generator

Summary

Generate 1-100 random letters with configurable case, vowel/consonant filters, separator, and exclusion list. Displays a live frequency chart.

How it works

1. The tool builds an alphabet pool from your selected options (vowels, consonants, or both), removes any excluded letters, then draws from that pool using rejection sampling over crypto.getRandomValues() to eliminate modulo bias. Results are joined with your chosen separator and displayed alongside a mini bar chart of letter frequencies.

• Create unbiased random letter sets for cryptography exercises or coding challenges.
• Pick random starting letters for creative writing prompts.
