VIBECHECK

AI VIBE
FORENSICS

AI-generated UIs leave a visible fingerprint — the same purple gradients, glassmorphic cards, hero-stat-FAQ scaffolding. VibeCheck scores how AI-generated your site looks — not whether AI wrote the code under it. A tasteful site fully written by AI scores low. A slop site hand-coded by a human still scores high. We grade the vibe, not the toolchain.

ANALYSIS_ARRAY_01

AESTHETIC FORENSICS

AI-generated UIs converge on the same surface — same gradients, same cards, same scaffolding. We measure the convergence. We don't care who typed the code.

ZERO TRACES.

WITH ZERO TRACES
PROTOTYPE

The web doesn't need more AI-generated sameness. Ship something that looks like you built it.

HOW IT WORKS
Submit any URL. We take a full-page screenshot, run headless Puppeteer, and score 45+ visual + structural heuristics across 5 categories. Output: 0–100, where higher = more AI-vibe.
WHAT WE GRADE
Look, not code. Purple gradients, uniform padding, card grid syndrome, hero-stat-FAQ scaffolding, AI copy tells, default icon libraries, palette homogeneity. We grade the vibe, not the toolchain — tasteful AI-coded sites pass.
OPEN SOURCE
VibeCheck is fully open. Run it locally, add it to your CI pipeline, or use it as a Claude Code skill. The detection algorithms are transparent — no black boxes.
