WebUI Bridge Negative Prompt

The WebUI Prompt Bridge main node is the big workspace, but sometimes you don't want a huge panel taking over the canvas - you just want a decent negative prompt box. That's this node: the small Negative Prompt chip with the pack's WebUI-style editing built in, minus the giant interface.

It's dead simple on purpose. One input, one output. Type your negative prompt (or drop down a tag from the autocomplete), and it hands you the text to feed wherever your workflow expects it. The value is in what surrounds the box: tag autocomplete backed by the pack's built-in Danbooru data, favorites, history, and the ability to edit as chips rather than raw text.

How it works

You might assume a "prompt" node would need a model and clip - it doesn't. This one is a pure text pass-through: negative_prompt string in, negative_text string out. It deliberately does no CLIP encoding and no LoRA handling. That's actually a feature: it slots into the standard ComfyUI chain where you'd normally use a CLIP Text Encode, but it's your negative text source. You'll typically run its negative_text output into a CLIP Text Encode (negative), or into the Bridge's own conditioning flow.

Where the node earns its keep is the editing experience. Because it shares the pack's tag data, favorites and history with the main node, you get the same autocomplete and chip-editing in a small footprint. The default negative prompt is the sensible anime-pipeline starter: worst quality, low quality, blurry, bad anatomy, extra fingers.

Inputs and outputs

• negative_prompt (required, multiline) - your negative prompt text.
• Output: negative_text - the string, ready to feed a CLIP Text Encode (negative) or the Bridge main node.

How to install

Part of the ComfyUI-WebUI-Prompt-Bridge pack. ComfyUI-Manager → ComfyUI WebUI Prompt Bridge, or:

cd ComfyUI/custom_nodes
git clone https://github.com/dianfangsihuo/ComfyUI-WebUI-Prompt-Bridge.git

Restart ComfyUI. It's under conditioning/webui. No models required.

Common issues

Because it only outputs text, people occasionally wire it straight into a KSampler expecting it to do something - it won't, and it shouldn't; it's a text source. If your autocomplete looks empty, remember the pack ships its own Danbooru tag data bundled, so check the startup/settings data source rather than assuming you need a WebUI installed. And one genuinely useful tip: since the negative chip and the main Bridge node share history, you can keep a couple of standard negative blocks in your favorites and apply them without retyping - the whole point of the pack is not having to rewrite tags every session.
