Visual Proof
UI Screenshot Diff Proof Studio
Compare before and after UI screenshots, generate annotated diff heatmaps, changed-pixel percentages, viewport proof sheets, and JSON evidence receipts.
CREATIVE SIGNAL LAB
Artifact-first tools for visual proof, release assets, style DNA, and seamless loops.
A professional browser-native lab for UI visual proof, audio release assets, style DNA extraction, and seamless audio loop repair with exportable proof receipts. Built for humans and AI agents that need evidence they can inspect, export, and hand off.

Release Pack
Audio Release Visual Pack Studio
Create a coherent release visual pack from a track brief: square cover, 16:9 thumbnail, 9:16 poster, waveform signature, palette tokens, and proof receipt.
Style DNA
Visual Style DNA Contact Sheet
Extract palette, contrast, density, shape language, prompt constraints, CSS variables, and a reusable style DNA receipt from reference images or a sample set.
Loop Repair
Seamless Loop Crossfade Builder
Repair clicks at the seam of a loop with equal-power crossfade, preview before/after seam metrics, export a WAV, and copy a proof receipt.
QUALITY RULE
Every run must create an artifact.
This lab exists because generic creative generators are easy to copy. These tools create files or visual proof, then attach a receipt: input summary, checks, warnings, export state, and the explicit boundary of what was not verified.
