Character Frequency Counter + Cipher Helper
A straightforward text analysis tool that counts how often each letter appears in your text and shows percentages. Useful for solving cryptograms, analyzing writing patterns, studying language statistics, or breaking simple ciphers. Paste any text and instantly see character frequency data without signing up.
How to use it
- Paste or type your text into the input field
- Choose case-sensitive or case-insensitive counting from options
- View the character frequency table with counts and percentages
- Export or copy results if needed for further analysis
Pro tips
- For cipher analysis, compare your frequency results against typical English letter distributions (E is usually most common)
- Use case-insensitive mode for cleaner analysis unless you specifically need to track capitalization patterns
- Remove punctuation and spaces first if you only want letter frequencies for cryptography work
