Characters include everything you type: letters (A-Z, a-z), numeric digits (0-9), punctuation marks, symbols, and whitespace (spaces, tabs, newlines). Letters strictly refer to alphabetic characters (A-Z, a-z, and international Unicode letters), excluding spaces, digits, and punctuation.

The Letter Frequency Analyzer calculates the exact count and percentage occurrence of every letter in your text in real time. It also contrasts your letter distribution with standard English letter frequencies (where 'E' accounts for ~12.7% and 'T' accounts for ~9.1%).

No. All text processing, frequency calculations, and metric extractions execute 100% locally in your web browser using JavaScript. No text, logs, or analytics are uploaded over the network.

You can set custom goal limits (e.g. 280 for Twitter/X, 500 for Threads, 160 for SMS, 60 for SEO titles) and choose whether to count letters only or all characters. A live progress meter indicates your percentage used and warns you when you exceed the threshold.

Yes. You can copy the full analysis summary to your clipboard, copy a formatted GitHub Markdown table (Alt+M), download a formatted text file (.txt), export the letter distribution table as a CSV spreadsheet (.csv), or download a complete structured JSON analysis report with customizable base filenames and date stamps.

On desktop devices, you can toggle between a 2-Column Side-by-Side Split Studio (editor on the left, live analytics and frequency distribution on the right) and a Full-Width Stacked layout by pressing Alt+V or clicking the header toggle. Your preference is automatically saved in your browser's local storage.

Clicking the '⚡ Code Snippets' button or pressing Alt+S opens an interactive modal featuring ready-to-use production algorithms for letter counting and frequency analysis in 6 languages: TypeScript/Node.js, Python 3, Go, Rust, Java, and Bash/cURL.

The tool utilizes modern Unicode character property regexes (\p{L}) to identify letters across alphabets (accented Latin, Cyrillic, Greek, etc.). Vowels include common accented variants (é, è, ü, ó, etc.), allowing precise calculation of vowel-to-consonant ratios regardless of input language.

Letter Counter provides high-efficiency keyboard shortcuts: press '/' to quickly focus the text editor, 'Esc' to clear workspace or close open modals, 'Alt+V' to toggle 2-Column Split Studio layout density, 'Alt+S' to launch Developer Code Snippets, and 'Alt+M' to instantly copy the GitHub Markdown summary table.

Switching from 'Grid View' to 'Table & Bars' provides a dense comparison matrix showing the exact count, share percentage, visual gradient distribution bar, English corpus benchmark percentage, and positive or negative deviation (+/-%) for each letter.
