Word boundaries use Unicode-aware segmentation. Counting is case-insensitive after NFC normalisation. The optional common-word filter is a fixed English list, not a universal linguistic model.

Frequently Asked Questions
How are words normalised?
Detected words are normalised to Unicode NFC and lowercased using the browser locale before frequencies are combined.
What does Ignore common words do?
It removes a fixed English stopword list after tokenisation. It is not language detection and should be disabled for other languages or when function words matter.
How are equal-frequency words ordered?
Results are sorted by descending count, then by the first position at which each word appeared.
What happens when every word is filtered out?
The tool shows an explicit no-results message rather than retaining an older table.
