Type‑Token Ratio plus MATTR moving average — see how much your vocabulary repeats.
Type-token ratio (TTR) is the simplest measure of vocabulary variety: unique words / total words.
Because TTR drops as text gets longer, this tool also computes the Moving Average Type-Token Ratio (MATTR) over a 50-word window, which is length-invariant.
You also get a list of "hapax legomena" — words that appear exactly once.
The ratio of unique words to total words. TTR drops as text gets longer, so it's sensitive to length.
Moving Average Type-Token Ratio. It computes TTR over a sliding window (we use 50 words) so the score is comparable across documents of different lengths.
