Character Frequency Map

Summary

The Character Frequency Map tool analyzes any pasted text and shows how often each character appears. Results are sorted from most to least frequent and include the raw count, percentage share, and a proportional bar chart so you can visually spot dominant characters at a glance.

How it works

1. Paste or type your text into the input area.
2. Use the toggles to include or exclude spaces and to treat uppercase and lowercase as the same character.
3. The tool counts each character in real time as you type.
4. Results appear sorted by frequency (highest first) with count, percentage, and a bar.
5. Click "Copy Table" to copy the results as plain text to your clipboard.

Use cases

• Analyze the character distribution of a cipher text for frequency analysis attacks.
• Check which letters dominate a writing sample for linguistic research.
• Compare character profiles of two different languages or writing styles.
• Verify entropy or randomness in generated passwords or tokens.
• Count symbol usage in source code or markup files.
• Identify repeated characters in user-generated content for moderation.
