What is character frequency analysis used for?

It's used in cryptography (breaking substitution ciphers), linguistics (studying language patterns), data quality (finding unexpected characters), and writing (analyzing text style).

Does it count whitespace?

Yes, by default. You can toggle 'Hide whitespace' to exclude spaces, tabs, and newlines from the chart while keeping them in the total count.

Does it support Unicode?

Yes. Every character is shown with its Unicode code point (U+XXXX). Emoji, CJK characters, and accented letters are all counted correctly.

Is my text sent to a server?

No. All analysis runs in your browser. Your text never leaves your device.
