FusionText

FusionText does one thing and does it without ceremony: it takes two text strings and glues them together. That's it. text_1 plus text_2, concatenated, out the single STRING output. There's no separator logic, no trimming, no template syntax - if you feed it "hello" and "world" you get "helloworld", comma and space included only if you put them there yourself.

For all that, it's genuinely handy inside this pack. The loaders hand you tag lists and selectors hand you prompt fragments, and at some point you need to assemble a prompt out of multiple fragments: the tags from a TagsSelector on one side, your hand-written prompt on the other. FusionText is the splice point. It's also a decent general "prompt stitching" node if you're building a workflow where different parts of the graph compute different chunks of the prompt - the forceInput on both inputs means they behave like proper wire sockets, so you can chain several of them end to end.

The author himself labels it a side node "kept here" while building the trigger-word pack, which is the right way to read it: it's not the star, but it's the connective tissue. If you're only here for LoRA tags, you can almost certainly live without it - ComfyUI's built-in text nodes and any of a dozen prompt-combiner nodes do the same thing. Reach for it when you want a zero-config joiner that plays nice with the LIST→STRING pipeline in this pack and you don't feel like installing another utility pack for a + operation.

How it works

Two required STRING inputs, text_1 and text_2, one STRING output. Under the hood:

return (text_1 + text_2, )

That's the entire mechanism. No surprises, which is the point. The one thing to keep in mind: because it's plain concatenation, you're responsible for spacing and commas. TagsSelector will happily hand you a string ending without a comma; decide where the joins go, or your prompt reads like a run-on sentence.

Installing

Part of ComfyUI-Lora-Auto-Trigger-Words. Install through ComfyUI Manager (search "ComfyUI-Lora-Auto-Trigger-Words") and restart, or:

cd ComfyUI/custom_nodes
git clone https://github.com/idrirap/ComfyUI-Lora-Auto-Trigger-Words

No dependencies, no downloads, nothing to configure. If you need more than a two-way join - three fragments, a separator, a template - grab a dedicated text utility pack instead; FusionText is intentionally minimal, and its value is that it stays that way.
