NovelAI Image Generator Enhancements

by Esbe1175/Archon

NovelAI Image Generator Enhancements is a userscript for Tampermonkey, Greasemonkey, or Violentmonkey, which brings quality-of-life and usability enhancements. Currently, it has a small but useful feature set, designed to fit in seamlessly with the NovelAI Image Generator's interface—as if it were meant to be there all along.

Installation

Choice of userscript extension

First, you will need to have a userscript extension installed. Choose one of the following:

• Tampermonkey: https://www.tampermonkey.net/ Supported by Chrome & Firefox
• Greasemonkey: https://www.greasespot.net/ Firefox only
• Violentmonkey: https://violentmonkey.github.io/ Firefox only

Installing the userscript

Second, you will need to install the userscript itself, which you can get from either of the following:

• GitHub.com: https://github.com/esbe1175/novelai-image-generator-enhancements/raw/refs/heads/main/novelai-image-generator-enhancements.user.js
• GreasyFork: https://greasyfork.org/en/scripts/535979-novelai-image-generator-enhancements

Feature Outline

Currently, NovelAI Image Generator Enhancements offers three features: Prompt Syntax Converter, Reference Strength Slider Patch, and the Smart Weight-Enhancer.

Prompt Syntax Converter

• One-click A1111 → NovelAI prompt conversion.
• Instantly convert Stable Diffusion WebUI (A1111) prompt syntax within the current prompt/negative prompt to NovelAI’s format.
• Accessible via a dedicated button next to the prompt settings icon.

Reference Strength Slider Patch

• Fine-tune the Vibe Transfer Reference Strength slider:
  • Range: allowed values down to -1
• Allows for more precise control over reference image influence.

Smart Weight-Enhancer

• Intuitive weight editing for prompt tags:
  • Hover over any weighted tag (e.g., 1.2::blue hair::) to see a tooltip with the current weight.
  • Scroll to adjust the weight:
    • Normal: ±0.05
    • Shift: ±0.01 (fine adjustment)
    • Ctrl: Snap to whole numbers (1, 2, 3, ...)

Example UI while hovering a weight

Note: This feature does not support the "old" {{{tag}}} / [[[tag]]] emphasis format, but it will not break it.
