About

Currently, when you attempt to install this extension, a dialog box may appear stating, "This extension is not trusted by Enhanced Safe Browsing." This message is displayed because I am a new developer, and it takes time for Google to recognize the extension as trustworthy.
If you have any concerns, you can review the source code on our support site.

This is an assistant tool designed to help you easily and flexibly create complex prompts on NovelAI's image generation page.
It includes features such as templates, wildcards, random selection, and weighting.
It supports notations up to NAI Diffusion V4.5 Curated.

Main Features:

- Template Function: Save frequently used word and phrase combinations as "templates" and recall them with a simple notation like T__templateName__T.
- Wildcard Function: Use the W__wildcardName__W format to randomly select one word from a registered list or insert the entire list concatenated with commas.
- Random Selection:
  - {A|B|C}: Randomly selects one from A, B, or C.
  - {2##A|1##B}: Weighted random selection where A is twice as likely to be selected as B.
These notations can also be used within templates and wildcards.
- Prompt Saving and Management: Organize and save your created prompts or frequently used prompt fragments in a folder structure.
- Generate & Copy with Ctrl+G: Press Ctrl+G to parse and expand the source of your input prompt, automatically copying the completed prompt to your clipboard.
- Data Persistence and Backup: Prompts you are currently working on, saved data, templates, and wildcards will not be lost even if you reload the browser. All settings can be exported and imported as a JSON file, allowing for backups.

How to Use:

- After installing the extension, open NovelAI's image generation page.
- Click the "Open Prompt" button displayed at the top of the screen (or in the specified location) to open the prompt input area.
- In the prompt input area, enter the source string for your prompt using the special notations described above. You can also save frequently used prompts in a folder structure at this time.
- Press Ctrl+G. The prompt will be generated and copied to your clipboard.
- Freely customize templates and wildcards on the options page.
