Anonymity fails on the small things. Two spaces after a full stop, a preference for the semicolon, a spelling you learned at school, a phrase you have used in something published under your own name: none of it survives being noticed, and none of it is removed by taking your name off the top. CADENCE measures the habits in a piece of writing, says which ones are unusual enough to matter, and tells you what to change.
What was measured
CADENCE cannot tell you whether you would be identified, and it does not try. Real authorship analysis compares a text against writing by a set of candidate authors, and the whole point is the comparison; this tool has no corpus and never sees anything but the text you paste. What it can do is point at habits that are distinctive enough to be worth normalising, and at phrases you should search for in anything already published under your name. Treat a clean result as "nothing obvious", never as "safe". The measurements get noticeably less reliable below a few hundred words. Everything is computed in this tab and nothing is stored.
Questions people ask
Can writing style identify an anonymous author?
It can narrow a field. Stylometry compares a text against writing by a set of candidates, using the habits nobody thinks to edit: how often ordinary function words appear, sentence-length rhythm, punctuation preferences, spelling conventions. It needs candidates to compare against, so in practice it identifies people who were already suspected rather than producing a name from nowhere.
What gives an anonymous writer away most often?
A reused phrase. A distinctive turn of words that also appears in something published under your own name is searchable, and it needs no statistics at all. After that: spellings that place you geographically, formatting habits such as two spaces after a full stop, and knowledge of a subject that only a few people have.
How do I write anonymously?
Normalise the habits, then have someone else read it. Standardise the spelling to one convention, remove the punctuation you favour, vary the sentence lengths, and search your distinctive phrases against everything already published in your name. Then remember that the metadata in the file, the account you post from and the hours you post at are usually easier to trace than the prose.
