Text Random Line

You want variety without chaos: paste a list of options, one per line, and have the node hand back a random one. That's Text Random Line. It's the node you use for random prompt variations, random subjects, random anything - except it has a seed input, which turns "random" into "random, but reproducible when you need it to be."

How it works

Two inputs: text (multiline - each line is a candidate) and seed (an int). The node splits the text into non-empty lines, strips whitespace, and picks one using Python's random module seeded with your value. Output is the single chosen line as random_line. Blank lines are skipped, so you can format your list loosely without counting empty lines in the odds.

The seed is the whole trick. Same text, same seed → same line, every time. That's what makes this usable in a real workflow: you can build a batch that runs N variations, lock a seed when you find a combo you like, and reproduce it exactly - or wire the seed to a counter to get a controlled sequence of different picks. Change the seed and you shuffle the deck.

Where it fits

The obvious use is prompt variety - a list of subjects, styles, or lighting descriptions, one randomly chosen per run. It's also handy for any small randomized choice in a workflow: random location names, random prefixes, random captions. If you find yourself hand-editing a Set Text node between runs to get variation, this is the automated version.

Installing it

Part of the Sage Utils pack - ComfyUI Manager (search Sage Utils) or:

cd ComfyUI/custom_nodes
git clone https://github.com/arcum42/ComfyUI_SageUtils
cd ComfyUI_SageUtils
pip install -r requirements.txt

Restart ComfyUI. Only pip dependency is dynamicprompts; no model downloads.

The catch

If your text is a single line, there's nothing random going on - you'll get that line back regardless of seed, and it'll look like the node is "broken." It isn't; it needs options to choose from. And remember the seed controls only this node's pick, not your sampler seed - if you want the whole workflow deterministic, the sampler seed and this seed need to be coordinated, not just this one. For picking a specific line rather than a random one, the pack's Text Select Line node is the sibling you want.
