I use a lot of reference characters and having to change the images, audio etc got annoying. I created a system that auto attaches the character reference, audio, description so you can keep your characters in a database similar to like an addon lora. It auto replaces yours tags with the reference slot it used and auto determines where each reference will go. Characters and audio get first slot since of the limited audio slots.

Example:
Prompt:
[Shot 1] {creature} stands at the bottom of {creepy_stairs}.
Output:
<Subject 1> (S1) is defined by the first reference image: a bald creature with prominent claws. <Audio 1> is the voice-timbre reference for <Subject 1> (S1): a creepy voice. <Subject 2> is defined by the second reference image: a staircase with spider webs and eerie lighting. [Shot 1] <Subject 1> (S1) stands at the bottom of <Subject 2>.

The mode auto injects only images and audio used, fills out the reference so you can auto pull in images and sound references you set in the reference node.

It creates a brand new mini webapp you can use to manage lots of characters and clips.

Currently no video references and sound, but may include it if there is enough interest.
