WHY BLINK WORKS

Your eye evolved
to catch motion.

Side-by-side comparison makes your eyes hunt. Blink comparison alternates images in place, so any change, down to a single pixel, registers as movement. The difference finds you.

STEP 01

Drop your images

Two versions of a photo, a whole Midjourney grid, before/after retouches — up to 50 at once. They never leave your device.

STEP 02

Blink, diff, or wipe

Alternation makes changes pop as flicker. Or heat-map the exact pixels, or drag a split line across the frame.

STEP 03

Mix & export

Draw a shape around any region and swap it in from your other images. Export as PNG, GIF, or MP4.

THE INSTRUMENT

SAME TABS AS THE REAL TOOL ↓

ALTERNATING @ 0.60s

Blink comparison — pixel-locked frames alternating gently

Pixel-diff heatmap: bright regions mark exactly which pixels changed between two variants

ΔMORE CHANGE

Generated mix one: anchor with the crystal region swapped in — MIX 1

2 SOURCES · 1 REGION → ALL 4 COMBINATIONS · REAL OUTPUT

Image layer animating between two keyframes — Compix interpolates every in-between frame

2 KEYFRAMES → COMPIX RENDERS EVERY FRAME BETWEEN

Blink — spot every difference. Alternation makes even one-pixel drift read instantly. REAL TOOL OUTPUT — NOT A RENDER

THE PART NOBODY ELSE BUILT

Your best image is hiding inside your other images.

Generation platforms profit every time you re-roll. Compix goes the other way: it extracts the exact pixels you already liked: the face from image 3, the outfit from image 7. Then it renders every combination. No AI model runs. No new generation. The face from image 3 is the face from image 3.

MORE THAN COMPARISON

It doesn't stop when you've found the best version.

Scene mode is a full layer compositor. Stack your images, place them, then set keyframes. The interpolation engine renders every frame in between, with bezier easing and a scrubbing timeline. Comparison finds your best frames; Scene puts them in motion.

PRIVATE BY DESIGN

Your images never leave this device.

NO UPLOAD

There is no server to upload to. Every pixel is processed by your own browser. Client work, NDA material, and unreleased art stay yours.

NO ACCOUNT

Open Compix, drop images, work. Projects save to your browser's local storage. We don't have a database to put them in.

OFFLINE

After the first visit, Compix works without internet. On a plane, on set, on a locked-down network.

FAQ

Quick answers.

Is this an AI tool?

No — and that's the point. Compix never generates pixels. It compares the images you already have and recombines their exact regions. Deterministic, repeatable, no hallucination. It pairs perfectly with AI tools: generate elsewhere, compare and combine here.

What happens to my images?

Nothing leaves your device. All processing runs in your browser; projects are stored in your browser's local database. Close the tab and we know nothing about you.

How is this different from Photoshop?

Photoshop can do a manual version of one combination. Compix computes every combination of your selected regions across all sources at once. Its comparison modes are purpose-built for spotting change, not editing.

What does it cost?

Comparing is free to use, no signup. Advanced features for heavy workflows are coming as a Pro tier. The comparison core stays free.
