Add String To Many

You've got eight different prompt strings and one thing you want in all of them - a quality tag, a style token, a character name, a "no text" kicker. Doing that with vanilla nodes means eight concatenation nodes and a wall of spaghetti. Add String To Many exists to make that a one-node job: it appends (or prepends) a single string to every string you feed it, and hands you all the results back.

It's a classic "utility" node in a pack that's half API glue and half CV - this one lives under Bmad/conditioning because its most common use is injecting text into a batch of prompts before they hit a CLIP Text Encode. The to_add string goes into each input either at the end (append) or the beginning (prepend), which is the other way to think about it: a shared suffix vs. a shared prefix.

How the inputs work - read this, it's the one tricky part

• to_add - the string to inject.
• operation - append or prepend.
• inputs_len (default 3, min 2, max 32) - how many string pairs are active.

And here's the gotcha the author flags with a ❔ in the docs: changing inputs_len does nothing until you right-click the node and choose "update I/Os." The widget stores the number; the socket count on the node is applied by the right-click action. Forget it and you'll be staring at three inputs wondering why your "8" didn't take. After updating, you get i1 … iN string inputs plus to_add, and the same number of STRING outputs, each ready to feed its own text encoder.

Install

Ships in bmad4ever/comfyui_bmad_nodes:

cd ComfyUI/custom_nodes
git clone https://github.com/bmad4ever/comfyui_bmad_nodes
cd comfyui_bmad_nodes
pip install -r requirements.txt

Restart, or ComfyUI Manager → search comfyui_bmad_nodes. The pack pins opencv-python~=4.8.1.78 and friends; no models, and this text node touches none of the CV deps anyway.

Gotchas

Beyond the "update I/Os" trap, the practical annoyance is that outputs are many separate STRING sockets - you're wiring a bundle of cables, not a list. That's by design (each feeds its own encoder), but if you need the strings as a list for a batch-style node, the pack's list utilities (ToStringList, FromListGetStrings) are the glue. And keep an eye on which side you're injecting: prepend is where style tokens usually go, append is where quality tags land - swapping them changes how the CLIP encoder weighs the text.
