Building tools I personally needed!

About

I build tools I personally need — and can't find anywhere. → Photo Style Unifier Presets copy colors, not mood. I built a tool that analyzes the perceptual signature of your reference photos — tone, atmosphere, how light moves through the frame — and transfers that look to any photo. No sliders. No generic filters. → SoundBound Japan has an incredible indie music scene that almost nobody can discover. Artists sell tickets through DMs. Venues have no online presence. I built a mobile-first platform for Japanese indie live events: discovery, ticketing, QR code entry — everything a small venue needs, nothing it doesn't. If something should exist and doesn't, build it.

Why I built this — presets that copy colors, not mood

I kept running into the same frustration: I'd find a photographer I loved,

apply their preset to my photos, and something felt off. The colors matched.

The mood didn't.

Presets describe a color grade. They don't capture how a photographer

Photo Style Unifier - Visual Atmosphere Ā· For Photographers

Photo presets are broken. They copy someone else's color grade — not your eye, not your mood, not the way you see light. Photo Style Unifier works differently. Upload 3–8 reference photos you love. The app analyzes their perceptual signature: how shadows behave, where saturation lives, the relationship between tone and light — then transfers that exact sensibility to any photo. No sliders. No generic filters. No subscription. Free to preview. Pay only when you download.
