What it does Stable.art is a UXP plugin for Photoshop 23.3+ that talks to an Automatic1111 backend over HTTP. You type prompts, select areas with any marquee or lasso tool, and get generated or inpainted pixels back inside your document. It also embeds a Lexica.art search for prompt inspiration so you don’t have to leave the canvas.

The interesting bit The plugin treats Photoshop’s selection tools as the entire UI for img2img/inpaint—no manual mask painting, no grayscale channel nonsense. Rectangle, lasso, magic wand: whatever you select becomes the operational boundary. It’s the rare AI tool that actually respects the host application’s native idioms instead of bolting a web form onto the side.

Key highlights

• Supports local Automatic1111 or remote endpoints (Colab, Gradio tunnels, etc.)
• txt2img respects arbitrary marquee dimensions, not locked to 512×512
• img2img/inpaint works with any Photoshop selection tool, no mask prep required
• Lexica.art integration for prompt discovery without context switching
• Distributed as a CCX file for one-click Creative Cloud installation

Caveats

• Outpainting is listed as “Coming Soon” with no timeline
• Only one release (v0.0.1) exists; the project appears early-stage
• Requires a running Automatic1111 API server—this is glue, not a standalone generator

Verdict Worth a look if you already live in Photoshop and run Stable Diffusion locally or via Colab. If you’re committed to ComfyUI, Krita, or pure web workflows, this adds nothing you don’t already have.
