category: quality-scorer
maturity: emerging
approach: Client-side (in-browser) pattern-matching scorer, not a trained AI classifier, that rates pasted text 0-100 across five dimensions: slop vocabulary (300+ overused words like "delve"/"leverage"), cliche phrases (80+ filler phrases), sentence-structure uniformity and em-dash density, vocabulary diversity (type-token ratio), and content substance (presence of concrete numbers/dates/names).
access: free
owns: A free, no-signup web tool (plus a Chrome extension for right-click-to-score selected text) that judges whether content is low-value "slop" and explains why, independent of whether the text is AI-written.
distinctFrom: Unlike sapling-ai-detector (which pairs an AI-authorship probability with a separate slop flag) or GPTZero/Copyleaks/Pangram (which classify AI vs. human authorship), SlopDetector makes no claim about who or what wrote the text at all: it scores generic, low-substance writing style regardless of origin, using deterministic pattern-matching rather than a trained classifier.
source: SlopDetector
notes: No individual creator or company named beyond "SlopDetector"; no public GitHub repo found, so the scoring logic is not independently auditable. Related blog content dated as recently as July 31, 2026, but the tool itself likely predates the 2026-07-27 window; flagged as an untracked gap-fill rather than a confirmed new launch. A near-identical competing site (issloppy.com / "SlopCheck", same client-side filler-phrase-and-structure mechanism) was found and rejected as redundant with this entry rather than added separately.
