SAX Text Catalog

SAX Text Catalog is a three-ring binder for your prompts, stored inside the node instead of scattered across text widgets. You keep a catalog of named texts - positive prompts, negative fragments, style blocks, whatever - and assign each one to an output slot through a relation. Flip which item a slot points to and every node downstream sees the new text without a single rewiring. It's the missing middle ground between "type your prompt every time" and "maintain a whole external prompt file."

The mental model is four layers, and the README states it cleanly: Catalog → Item → Relation → Slot. The Catalog is the storage, an Item is one named text with tags, a Relation is the mapping between an Item and an output, and the Slot is the actual output pin that gets auto-generated. You edit items in a Manager Dialog (search, tag filter, a nice wide text editor); you edit relations in the node body.

How it works

Each relation row has a toggle and an item picker. The toggle is the killer feature: flip it off and the slot outputs "" instead of the text. That's how you mute a prompt fragment without deleting anything - and because SAX Prompt Concat skips empty strings, an unset or disabled relation just disappears from the final prompt instead of injecting a blank line. Orphaned relations (items you deleted) also output empty string, and connections to downstream nodes survive even when you delete an item, so your graph doesn't fall apart mid-edit.

The outputs are out_0 through out_31 (STRING), each wired to wherever that text is needed. Wire them into SAX Prompt Concat for prompt building, or into a SAX Prompt via converted inputs. The select_to_add_lora and select_to_add_wildcard combos are just UI sources for the editor's pickers.

If you have pythongosssss's ComfyUI-Custom-Scripts installed, the text editor gets danbooru tag autocomplete - type and it suggests tags. Without it, manual input still works fine.

When you'd use it

• One shared negative across multiple samplers, edited in one place.
• A set of style fragments you swap between runs by toggling relations.
• Prompt variations keyed to scenes, switched from a Toggle Manager instead of retyping.

Installing it

It ships in the SAX_Bridge pack. ComfyUI Manager → "Install via Git URL" → https://github.com/so16tm/SAX_Bridge, or:

cd ComfyUI/custom_nodes
git clone https://github.com/so16tm/SAX_Bridge

Restart, and it's under SAX/Bridge/Utility. The autocomplete is optional (ComfyUI-Custom-Scripts), and wildcard-style expansion of catalog text happens downstream in the SAX prompt nodes, which need comfyui-impact-pack - the catalog itself needs neither.

Gotchas

Two things to know before you lean on it. First, this node stores and routes text - it does not do wildcard expansion itself, so a __wildcard__ token in a catalog item only expands if whatever's downstream does the expanding. Second, because it's a JSON-backed node managed by its own UI, copying workflows between different ComfyUI versions occasionally reshuffles relations; when a relation shows up as <orphan>, you deleted the item or the reference broke - the slot stays, the output is empty, and the fix is re-picking the item.
