Analyze Your Text's DNA

The Find Unique Letters tool breaks your text down to its atomic level. It ignores words and sentences to focus on the individual characters that build them. Whether you're a designer checking a font's glyph coverage, a developer sanitizing input, or a linguist analyzing alphabet usage, this tool reveals exactly what's inside your string.

Character Analysis Features

Charset Detect

Instantly tells you if your text contains only standard ASCII or if hidden Unicode/Emoji characters are present.

Visual Cleanup

Filter out the noise. Hide spaces, tabs, and punctuation to focus strictly on letters and numbers.

Why extract characters?

It's about data validation and precision.

  • Designers: Check if a font supports all characters in a headline.
  • Developers: Find illegal characters in a database dump or input field.
  • Cryptographers: Analyze the alphabet size for cipher cracking.
  • Linguists: Check alphabet usage distribution.

Frequently Asked Questions

What does this tool do?

It scans your text and creates a list of every distinct character used. If you paste 'Hello', it returns 'H', 'e', 'l', 'o' (the duplicate 'l' is removed).

Does it detect emojis?

Yes! The tool fully supports Unicode and will identify and list any emojis present in your text as unique symbols.

Can I use this for programming?

Absolutely. It's great for sanitizing inputs, checking for illegal characters in strings, or building regex character classes.

What is 'Charset Info'?

This tells you if your text contains only standard English letters (ASCII) or if it includes special international characters or symbols (Unicode).

Can I filter out numbers?

Yes, enable the 'Ignore Numbers' filter to see only the alphabetic characters and symbols in your list.

Is it case sensitive?

You can choose. By default, 'A' and 'a' are treated as different unique characters. Uncheck 'Case Sensitive' to treat them as the same.

Does it work with code files?

Yes, you can upload .js, .css, .html, or .json files to see exactly which symbols and characters are used in your codebase.

Is my data secure?

100%. All processing happens in your browser. No text is ever uploaded to our servers.

Why remove duplicates?

Removing duplicates helps you see the variety of characters used, rather than the quantity. It's essential for font testing and cryptography.

Can I download the result?
