Character frequency
What is Character Frequency Analyzer?
Counts how often each character (letter, digit, symbol, space) appears in your text and shows frequency percentages with a visual bar chart. Can filter to show only letters, only digits, or all characters.
Common Use Cases
Cryptanalysis and cipher cracking, typography analysis, keyboard layout optimisation research, linguistics, and text pattern discovery.
How It Works
Iterates over every character in the text, builds a frequency map, sorts by count descending, and renders a visual bar chart.
Frequently Asked Questions
Can I filter to show only letters?
Yes. Toggle between "All Characters", "Letters Only", and "Letters + Digits" modes.
Is it case-sensitive?
You can toggle case-sensitivity. Case-insensitive mode merges uppercase and lowercase counts.
