# Chatouch

Chatouch is a free browser-based utility for gently refining images generated with ChatGPT. Its Japanese headline is "ChatGPTの画像をきれいにしましょ".

## What it does

- Accepts PNG and JPG/JPEG images.
- Applies a fixed local image-processing pipeline derived from the original Chatouch development tests. One output-strength slider ranges from 0 to 100, defaults to 50, and reproduces the original fixed result at 80.
- Preserves the input pixel dimensions.
- Exports PNG.
- Shows a pixel-aligned Before / After comparison.
- On supported iPhones, the result can be passed to the iOS share sheet for saving to Photos.
- On desktop, the result can be downloaded.

## Privacy

Image pixels are processed in the user's browser. Chatouch does not upload input or output images to a server.

## Processing

The public version uses a fixed OpenCV-based pipeline: smooth sub-pixel deformation, a small local luminance field, colored non-local-means denoising, a 0.90x resample round-trip restored to the original dimensions, and mild detail restoration.

Changing strength blends the saved original and baseline pixels in the browser; it does not rerun OpenCV or upload the image.

Chatouch is not an upscaler and does not increase pixel dimensions.

## Formats
