GPlanSiS Studio

What works the same as Photoshop

• Layers with blend modes, masks and adjustment layers, plus brush, selections and text.
• Open PSD files with all their layers and save PSD with layers.
• Non-destructive adjustments and filters, and smart fill to remove what you select.
• A Photo module that lays out a catalog, ratings, quick develop and presets the way Lightroom's Library does.
• Open almost any image format: HEIC, TIFF, WebP, AVIF, RAW and more.

What is missing

• RAW files open only as their embedded JPEG preview.
• AVIF export works only where your browser can encode it.

How to get started

1. Download the project from its page. There's no installer: you need Python 3.10 or later and a modern browser.
2. In its folder run python3 build.py, then start the server as the project page explains.
3. Open http://127.0.0.1:8972, sign in with the master email and password from your .env file, and set a new password. The Demo button loads a sample project.
4. The optional AI menu sends a reduced copy of your image to Anthropic's Claude; everything else stays in your browser.
