Lipogram checker
Check whether a text is a lipogram — writing that deliberately avoids one or more chosen letters, like Perec's novel that never uses the letter e. Enter your forbidden letters and it counts every violation, shows which banned letters slipped through, and gives a purity score. Accents fold to their base letter.

Frequently asked questions
What does Lipogram checker do?
Check whether a text is a lipogram — writing that deliberately avoids one or more chosen letters, like Perec's novel that never uses the letter e. Enter your forbidden letters and it counts every violation, shows which banned letters slipped through, and gives a purity score. Accents fold to their base letter.
When would I actually use this?
Fitting a piece to a limit: an essay to a word count, a post to a network's cap, a meta description to what a result page will show.
What is the most common mistake?
Assuming one character equals one unit of the limit. An emoji can cost two or more, a combining accent can cost two, and several platforms bill a link at a flat rate regardless of length.
What else is filed next to it?
Pangram checker, Pig Latin translator and Smart quotes remover share its section. They are not variants of it — being filed together is not the same as being alike — but that is where to look if this turned out not to be the tool you wanted.
Where do the figures come from?
Counting follows Unicode: the tool reports code points and grapheme clusters separately, because they differ for emoji and combining marks. Per-network limits come from each platform's published specification.
