LLM Slop Detector

Flags invisible Unicode, AI-style punctuation, and telltale LLM phrases as you type -- or in any page you're reading. Local only. LLM Slop Detector highlights the things that give AI-generated writing away: invisible Unicode smuggled inside text, em dashes and curly quotes that spell-checkers ignore, and phrases like "delve into", "tapestry of", "it's worth noting", or "game-changing" that appear far more often in LLM output than in human writing.

It works in two ways:

As you write

• Scans every textarea, text input, and contenteditable on any webpage.
• Inline wavy underlines mark flagged words and phrases. A floating badge shows the count. Click it for per-finding explanations.
• One-click fixes for deterministic characters (em dash -> hyphen, curly quotes -> straight, zero-width spaces -> deleted). The fix goes through the host editor's native undo stack, so Cmd+Z works.
• Tested in Gmail compose, Proton Mail compose, GitHub issue forms, Reddit, Substack, and anything else built on plain contenteditable.

As you read

• Click the "Scan this page" button in the toolbar popup to highlight slop in any article, blog post, or thread you're reading. Wavy underlines go under flagged words; a floating results panel lists every finding and jumps you to it on click.
• One-shot, click-to-scan only. No background scanning.
