DualPromptDrafter

You're looking at the old name of a node that still exists. DualPromptDrafter was the registration key for the pack's main dual-prompt node until v1.3.3, when ComfyUI-PromptDrafter standardized all its node names to the Name_PromptDrafter scheme to stop collisions with other packs. The current, menu-visible node is Dual_PromptDrafter (displayed as "Dual Prompts - PromptDrafter"). This page still exists because old workflows carry the legacy key, and ComfyUI has to resolve it when you load one.

So if a workflow you downloaded shows a DualPromptDrafter node, nothing is broken - it's the same green-positive / red-negative prompt pair with the same inputs and outputs: positive_prompt and negative_prompt text boxes, optional positive_prefix/positive_suffix/negative_prefix/negative_suffix strings, the prompt_name/load_prompt save pair, and the positive_prompt, negative_prompt, positive_raw, negative_raw outputs. The pack registers it as a deprecated shim that DEPRECATED = True, which means it loads saved workflows fine but is hidden from the Add Node menu - you can't search for it and add a fresh one, by design.

What to do

Two options. Easiest: leave it alone. Legacy workflows keep working, and the node is functionally identical to the new one. Cleaner: right-click and replace it with Dual_PromptDrafter, then re-wire. There's no migration script, but the sockets are identical so it's a two-minute job, and doing it means your workflow no longer depends on a compatibility path that could eventually get dropped.

Installing

You don't install this node specifically - it comes with the pack. ComfyUI Manager (search "PromptDrafter") or:

cd ComfyUI/custom_nodes
git clone https://github.com/Carasibana/ComfyUI-PromptDrafter

Restart after. No dependencies beyond ComfyUI, no model downloads. If you're just adding nodes fresh, search the current name instead and you'll never see this page again.
