compare_to_baseline
Check if a text fits a writer's usual style by comparing function-word frequencies against earlier samples, returning distance measures and highlighting unusual word usage.
Instructions
Compares one piece of writing against several earlier pieces by the SAME person, using function-word frequencies (Burrows's Delta). Returns how far the questioned text sits from that writer's centre, alongside how far each of the writer's own pieces sits from it — measured identically, so the scale is the writer's own variation rather than a threshold invented by this tool. Also returns which function words differ most, with rates per 1,000 words, and how many words are used at a rate the writer has never used them at. Runs fully offline; nothing is sent anywhere. WHAT THIS CANNOT DO: it cannot tell you who wrote something. There is no "different author" result and there must not be one in your summary either. Style moves with the assignment, the genre, the deadline, a co-author, an editor, and with a person simply getting better. A text outside the range is a reason to ask what changed; it is NEVER a conclusion, an accusation, or evidence of misconduct. The most valuable outcome is the reassuring one: a text INSIDE the range settles a suspicion, and saying so plainly is usually the most useful thing you can do with this tool. It refuses to answer on thin evidence and returns "Undetermined" instead of a number — do not work around that by rerunning with less text or by estimating one yourself.
