3x3 Image Segmentation Tool

Visual concept: previously, I used to send a 3×3 grid to Nano Banana Pro and ask it to extract an image by “row and column” — and it failed way too often. So I ended up building a small tool myself: Just upload an image ✅ Automatically generate a 3×3 grid ✅ Split it instantly and export any single cell in high resolution ✅. Iteration: clone the same subject in a flat illustration style for thumbnails.
