Letter Counter by Frequency
Count how often each letter A-Z appears in a text, shown as a heatmap-shaded grid with live totals, entirely in your browser.
🔒 This tool runs entirely in your browser. Your files are never uploaded to a server.
Example shown — replace it with your own text. Case is ignored; only letters are counted.
How the letter counter works
- Paste or type your text.
- The tool counts how many times each letter A-Z appears, ignoring case, numbers, and punctuation.
- Each letter is shown with its count, shaded more intensely the more frequently it appears.
FAQ
Why are numbers and punctuation excluded?
This tool specifically counts letter distribution (A-Z), so digits, spaces, and punctuation are skipped — they'd clutter a 26-letter frequency view without adding useful information about letter usage.
What is this useful for?
Analyzing writing style, checking for overused letters, word game strategy (like figuring out which letters are still available in Wordle-style games), or just satisfying curiosity about a text's letter makeup.
Does it distinguish uppercase from lowercase?
No — "A" and "a" are counted together, since letter frequency is normally discussed without regard to case.
Is my text sent anywhere?
No. Every count is calculated instantly in your browser as you type — nothing is sent to Online Tool Store or stored.
