How this works
Enter the values shown, review the result, and verify assumptions before acting. The calculation is performed on your device without uploading these entries.
Find words that match a supplied pattern among words you paste. The input fields are labeled with the units or formats used in the calculation. Change one value at a time to see how the result responds, and compare the output with the worked example below.
Formula or method
The method above describes the calculation or algorithm being used by this browser utility. It is shown so you can understand the result, check assumptions and repeat the calculation independently if needed.
Worked example
Pattern c?t matches cat and cot from an entered list.
Limitations and accuracy
This tool uses your supplied candidate list, not a comprehensive copyrighted dictionary.
The calculation runs locally in your browser. No result is guaranteed to be suitable for financial, legal, medical, or safety-critical decisions. Check independent authoritative sources in those cases.
More context
Character count, word count, sentence count and reading time answer different questions. Unicode text can include composed characters and scripts that do not use spaces between words, so simple counts are estimates rather than linguistic analysis. Readability formulas are useful only for the languages they were developed for. Working locally keeps drafts in the browser unless a feature specifically requests an external service.
