YC text box combine

YC text box combine is a prompt authoring convenience: five multiline text boxes (or wired string inputs) in one node, plus a separator, and it outputs the five parts and the combined string. So you can build a prompt out of components - subject / style / lighting / camera / negative-ish bits - keep them as separate editable boxes, and still hand a single assembled string to your CLIP encoder.

The real appeal is the five passthrough outputs (text1_out … text5_out). Because each input is echoed out individually, the node doubles as a clean junction point: you can tap one component for a different branch (a filename label, a caption, a separate encode) without having to split the combined string back apart. It's the "keep my prompt modular" node.

How it works

Five strings plus a separator (default a single space) get joined in order. Nothing else - no case handling, no trimming, no weighting logic. If a box is empty, you get the separator anyway unless you're careful (empty text2 between filled neighbors yields a double space; feed empty-string-aware behavior yourself or just don't leave gaps).

The inputs that matter

text1 through text5, all multiline, and separator. That's the whole surface. Outputs: text1_out … text5_out (each echoing its input) plus combined_text (the joined result). For SD/SDXL-style prompts, a space separator is right; for booru-tag style, you might want , .

Gotchas

The separator is always inserted between boxes, even empty ones - five boxes with only text1 filled produces "your text" plus four trailing spaces unless you account for it. Not a bug, just literal. And while the passthroughs are handy, remember they're echoes of inputs; if a box isn't wired it returns its default placeholder text ("text1" and friends), which you do not want in a real prompt - either wire them or clear the defaults. For combining prompts with LoRA trigger words or dynamic content, a wildcard-capable combiner is more powerful; this one is the simple, readable option.
