ComfyUI Strings&Things

A collection of ComfyUI custom nodes for formatting and debugging string data with the intention of collecting generation data to be processed by a custom node pack like comfy-image-saver, as well as miscellaneous extra nodes that I find useful or interesting to experiment with. Nodes are not currently set up to take batched inputs.

Part 1 - String Formatting

Lora Selector - lets you pick a LoRa while also outputting its name as a string.

Lora Name Collector - takes up to 5 LoRas, should now work chaining multiple together for >5 loras.

Debug String - Attempts to print input to the console. Primarily useful for strings, but tries to take anything as input.

Formatting and Concattenating 3 Strings - Added pre and post text to up to 3 input strings and concatenates them in order with a separator. Empty body inputs will not have their pre and post text included.

Formatting Single String - Pre and post text for a single string.

Part 2 - Extras

Mosaic Effect Node - Applies a mosaic effect (aka tile censoring) to the entire image. Useful for pixelart style generations, or in combination with BBox/SEGS for censoring. (Example workflow are available in the 'Example workflows' folder)

Fourier Analysis Node - Some people claim some stuff about AI and repetitive patterns being visible in the fourier analysis. Don't ask me, I'm not a scientist, I just think they look cool.

Text Embedding Interrogator - Calculates the Cosine Similarity and Euclidean Distance between the Pooled Attention CLIP text embeddings for two embeddings.

Image Difference - Calculates the simple pixel-wise difference between two images and outputs an image of the result. It also calculates the Mean Square Error as a measure of difference between the images and displays the value in the console as a percentage (0% = same image, 100% = one black vs one white image). The SME calculation can be skipped by toggling console_mse to false. For images with subtle differences you can toggle contrast_boost to true, increasing the magnitude of the displayed differences by a factor of 5.
