Live analysis of any text: pangram, perfect pangram, heterogram, lipogram and alphabet-anagram tests, with per-letter counts, missing letters and a frequency chart.

35 letters analysed · 26 of 26 distinct

Verdicts

  • Pangram: yes

    All 26 letters of the alphabet appear at least once.

  • Perfect pangram: no

    A perfect pangram needs 26 letters with no repeats. This text has 35 letters and 6 repeated letters.

  • Heterogram (isogram): no

    Repeated letters: E H O R T U.

  • Anagram of the alphabet: no

    Not possible yet: the text does not hold exactly the 26 alphabet letters.

  • Lipogram (no "E"): no

    The letter E occurs 3 times, so this is not a lipogram on E.

The classic shortest perfect pangram: 26 letters, each used exactly once. It leans on rare loanwords and abbreviations — cwm (a Welsh valley), fjord (Norwegian), glyph, vext (an archaic spelling of vexed) and quiz — so many word lists dispute it. It is legitimate as a letter-set, not as everyday English.

About this tool

This checker runs five classic letter-set tests on whatever you type — pangram, perfect pangram, heterogram/isogram, lipogram on a letter you choose, and the anagram-of-the-alphabet test (which is the perfect-pangram condition expressed as multiset equality). It also counts every letter A–Z, lists what is missing and what repeats, and charts the letter frequency.

Non-letters are ignored for letter logic and only the 26 ASCII letters A–Z count toward the pangram test; accents, digits, punctuation and other scripts are ignored for letter logic, and upper and lower case are treated identically. Everything runs in your browser as you type — no text is uploaded or stored anywhere.
