Background Prompter

Background Prompter

Background Prompter is a visual background-prompt browser extension for Stable Diffusion WebUI Forge Neo and ReForge.

It is a Forge port of the background preset/effect portion of my ComfyUI project, Krea2 BBOX Prompter Suite.

As of July 2026, it includes 592 background presets with matching preview thumbnails. Browse backgrounds visually, search by name or category, filter recent and favorite items, adjust thumbnail size, and select a preset.

The generated prompt is shown in an editable field before insertion.

Features:

- Compact tag-based output for SD, SDXL, and Illustrious-style models

- Natural-language output for Anima, Qwen, ZImage, Clear2, and Ernie Image

- Hybrid and automatic prompt selection based on the selected Forge Neo UI preset

- Optional Realistic and Anime style boosts

- Direct insertion into txt2img or img2img

- Copy, reset, favorite, search, category filtering, and pagination controls

- Inline panel, sidebar, and browser-tab viewing modes

- All generated prompts can be edited manually before use

The prompts are designed as background support rather than strict scene locking. They avoid unnecessary repeated words and forced anti-subject phrases, leaving room for the user's main subject and additional prompt edits.

Installation:

1. Download and extract the ZIP file.

2. Copy the background-prompter folder into the extensions folder of Forge Neo or ReForge.

3. Restart WebUI.

Do not place the ZIP file itself inside the extensions folder. No checkpoint, LoRA, embedding, or additional model weights are required by this extension.

Usage:

1. Open the Background Prompter tab.

2. Search or select a background preset.

3. Choose the output mode or leave it on Automatic.

4. Edit the generated prompt if needed.

5. Insert it into txt2img or img2img, or copy it manually.

The extension follows the Forge Neo localization setting. None uses English by default; selecting Japanese uses Japanese labels where available.

This is an extension package, not a checkpoint, LoRA, embedding, or base model. For Civitai version metadata, use Base Model: Other.
