Summary

Paste any text and instantly see each character ranked by frequency with counts, percentages, and a visual bar chart.

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.
