N-gram frequency analyser
Find repeated word phrases or character sequences in local text.
A clear answer. Here’s how.
Counts overlapping windows of length 2–5 across at most 100,000 characters. Word mode lowercases and extracts Unicode letters/numbers with internal apostrophes, ignoring punctuation boundaries; character mode includes exact whitespace and case. Sorts frequency descending, then lexical spelling. Percentages use all windows, not just top results. Does not perform linguistic segmentation or semantic phrase extraction.
