Methodology

VibeTier scores how closely a site matches common AI-generated landing page patterns (loud gradients, bento grids, copy slop). Higher scores mean more "vibe-coded" — not proof of AI authorship.

prd-v0.1 model

• Copy slop uses an optional LLM pass on visible text only; rules fill in when the LLM is off or fails.
• 101 rule-based detectors roll up into six categories; ordinal hits map to category points (max 100).
• LoL-style tiers run from Iron (low) to Challenger (high). See rubric and result disclaimers for limits.
