EmAySee Remove Words From Text

Strip specific words out of a longer text. Give it a main string and a comma-separated list of words to delete, and it returns the text with those words gone - matching whole words only, case-insensitively, and collapsing the leftover double spaces so you don't end up with holes. It's the "clean this up before it hits the CLIP encoder" node.

How it works

Two inputs:

• main_text (multiline) - what you're cleaning. Defaults to A dog, a cat, and a bird.
• words_to_remove (multiline) - comma-separated words to delete, defaulting to dog, cat, and.

Output cleaned_text. The mechanism is a regex built from your words (escaped, so punctuation in words doesn't break it), wrapped in word boundaries \b(...)\b so it only matches whole words - cat won't touch caterpillar. It matches case-insensitively (Dog gets removed too), and after removal it squeezes runs of multiple spaces down to one and trims the ends. So the default input gives you A , a , a bird. - wait, no. With "and" removed and spaces collapsed, you get A , a , a bird. Hmm, the comma stays because it removes the word, not the punctuation. Real output from the default would be something like A , a , a bird. - the commas survive and look awkward.

That's the honest gotcha: this node removes words, not punctuation or the surrounding grammar. "Remove dog, cat, and from A dog, a cat, and a bird." leaves you with A , a , a bird. The sentences are no longer grammatical - there's no smart re-joining. For tag lists (the common use case) that's fine: red hair, smiling, red hair minus red hair gives , smiling, and you may want to run the result through a dedup/cleaner afterwards. For flowing prose, expect punctuation leftovers.

Where it fits

• Stripping unwanted tags out of an auto-generated caption before encoding.
• Removing "quality boosters" (masterpiece, best quality) from a copy of a prompt to A/B test their effect.
• Banning a trigger word from a batch of prompts.

Installing it

Part of ComfyUI_EmAySee_CustomNodes. ComfyUI Manager → search the pack title → Install, or:

cd ComfyUI/custom_nodes
git clone https://github.com/EmAySee/ComfyUI_EmAySee_CustomNodes
# restart ComfyUI

Under EmAySee_Text, no dependencies - it's re.sub with a bit of cleanup.

Bottom line

A precise word-removal tool that won't mangle substrings but also won't fix your grammar. Feed it tag lists and you're golden; feed it prose and accept the orphaned commas.
