Show HN: Detecting AI-written copy without an LLM (deterministic, client-side)

Score: 4.3/10 (Innovation: 5, Technical: 4, Documentation: 2, Utility: 4)

A client-side landing page copy grader that scores headlines, subheadings, and CTAs from 0-100 for how generic or AI-generated they sound, using deterministic heuristics rather than an LLM. It's interesting as a lightweight, privacy-friendly tool for solo founders to quickly sanity-check their copy, though the landing page itself appears to be a thin wrapper with limited documentation.

Target audience: marketers and solo founders
