    Hello there and thanks for checking out this workflow!

    Purpose

    This workflow makes even the most subtle changes to a prompt immediately visible, showcasing the differences next to each other in a side-by-side comparison.

    Features

    • Full metadata; recognized by CivitAI

    • LoRA support

    • Custom comparison mode to visualize even slightest differences

    Questions this workflow can answer—Can you?

    Which prompt/quality prettifiers are the best or help at all ?
    → best ultra-mega-quality 64K ...

    Do words with the same meaning have the same effect ?
    → big ↔ huge ↔ giant ...

    What really happens when changing a word in the negative ?
    - With the negative prompt basically happening behind the scenes so to speak, it's very easy to have a mediocre negative that still seems alright, but could be better by a whole lot, probably shortened, too

    Does order matter ?
    → best, masterpiece, prompt → prompt, best, masterpiece

    Yorkshire tea or Starbucks coffee?
    - UK ↔ US spelling : doughnut, icing, red-pink colour, ... mate

    How important is punctuation really ?
    → cabin, forest; fire-axe ↔ cabin. forest-fire, axe ...

    Are prompts case-sensitive ?
    → does it help to YELL ?!

    Spacing between words is one thing, but what about within ?
    → candle light ↔ candlelight ↔ c a n d l e light ...

    Are typos still understood ?
    → 1gril best beuty...

    Are special symbols like alt-codes or emoji recognized ?
    → 1girl, ❤️, harley quinn, ♦-tattoo, 😁 expression, †edgy† outfit

    Custom Nodes used

    All of which can be installed through the ComfyUI-Manager

    If you encounter any nodes showing up red (failing to load), you can install the corresponding custom node packs through the 'Install Missing Custom Nodes' tab on the ComfyUI Manager as well.


    Thanks

    The workflow would not be possible as is without these custom node packs. If you want to support the custom node creators, give them a ⭐ on their github repos! Thank you!


    Feel free to ask any questions, share improvements or suggestions in the comment section!
    Also let me know if you encounter any confusing points I can elaborate on and focus on improving for the next update!

    @Bliney Hey there, don't worry, that is most likely not an error on your part, but caused by ComfyUI's breaking updates. I needed to un-group-node every single workflow first, before I could even update to the newest version and am still in the process of bringing everything up to scratch despite the changes.

    A fully functional update will be up in a few days, sorry about the inconvenience 🙏
