ComfyUI-PromptSwitch: Dramatically Speed Up Your Prompt Workflow!

Prompts ON/OFF switching and weight adjustment can be done intuitively like a checklist with this custom node.

Welcome to "PromptSwitch," published on GitHub!

This is a version that dramatically improves prompt management and usability, based on the ideas of Prompt Palette.

To distinguish the origin of the features, we use the following notation:

• [Original]: Basic features inherited from Prompt Palette
• [Switch]: Features added or improved in PromptSwitch

Key Features

*Images might be outdated.

Please refer to the list below for the latest shortcuts (R key → Random, W key → Reset, C key → /C Toggle, etc.).

The format for tags in the node title is / delimited. Example: /a/r/R0-4/C (formats like /ra are now invalid).

Each prompt line can be manipulated independently and customized.

1. Interactive Prompt Management

In non-editing mode, each line is displayed like a checklist.

• [Original] ON/OFF Switching for lines
  • Click a line to enable/disable it (prefixed with //)
• [Original] Weight Adjustment
  • Use the + / - buttons on the right of the line to adjust weights in increments of CONFIG.WEIGHT_STEP (default 0.10)
• [Original] Operable even in Edit Mode
  • You can repeat execution while editing
• [Switch] Empty lines are displayed as separators
  • These separators are also used to define groups for random pickup
  • Displayed as a faint light blue line (#ADD8E6)
• [Switch] Separator Line //,//
  • //,// → Displays a gray line (#888) as a separator (purely for visual organization)
  • //,// Comment → Displays in light blue text (#ADD8E6) (a comment line not used as a prompt element)
• [Switch] Display Improvements
  • Long lines are automatically truncated (max 30 characters + ...)
  • For comments (the string after //), the // is hidden, and the font size is 80% with color #ADD8E6

2. Mode Switching

• Edit Mode
  • F2 or E key, or double-click the node border (left, right, and bottom borders only; top is not possible)
• [Switch] Compact Mode
  • V key: Hides disabled lines (minimizes height)
  • Shift+V: Toggles all nodes simultaneously (excluding nodes with /v)

Shortcut Keys (Latest Version)

Key	Function	Description
F1	Show Help	Explanations of shortcuts and tags
F2 / E	Toggle Edit Mode	Normal Mode ↔ Edit Mode
Shift+E	Toggle Edit Mode for ALL Nodes	Useful in edit mode because browser search highlighting works (but jumping is not possible)
A	Batch ON/OFF	Toggles all lines in the selected node
Shift+A	Force Disable All Nodes	Comments out all nodes (excluding /a). Useful when you want to reset everything.
V	Toggle Compact Mode	Hides disabled lines in the selected node
Shift+V	Toggle All Nodes Display	Toggles all nodes to Compact/Normal simultaneously (excluding /v)
W	Instant Weight Reset	Resets all weights in the selected node to 1.0
R	Random Pickup	Randomly selects from sections separated by empty lines (supports /R tag)
Shift+R	Randomize All Nodes	Performs random pickup on all nodes (excluding /r)
C	Toggle /C Tag	Adds/removes /C to the title. Toggles the trigger for automatic random pickup during image generation.
Shift+C	Remove /C from All Nodes	Removes /C from all nodes simultaneously

The Ultimate New Feature: The /C Tag (Automatic Random Update on Every RUN Button Press)

"Every time you press the RUN (Generate) button, the prompt automatically changes randomly." This is PromptSwitch's biggest strength.

How to Use (Just 2 Steps)

1. Add /C to the node title (The C key can toggle /C) (Example: Face Expression /R0-3 /C)
2. Press "RUN (Generate)" → Each time you press it, one element in the node is automatically selected randomly, and an image is generated. (By adding the /R1-3 tag, you can pick up 1 to 3 elements simultaneously. By using /R-100-2, you can make the tag super rare, selecting 1-2 elements about once every 100 runs.)

Strengths of the /C Tag

Conventional Method	With /C Tag
Manual update with R key every time	Automatic update with RUN (Generate)
The same prompt continues	A different configuration every time
Trial and error is tedious	Reaching the desired image in the shortest path

Randomness is Fully Controlled by the /R Tag

• /R1 → Always selects exactly 1 item randomly
• /R1-3 → Randomly selects between 1 and 3 items
• /R-5 → Randomly selects between 0 and 5 items
• /R-3-2 → Randomly selects between -3 and 2 items (Negative value = 0 selection, 3 "miss" slots added, 3 misses out of 6 total possibilities, 0 probability ≈ 50%) → You can try variations with a single press of the RUN (Generate) button, while narrowing down to a "target style"!

Ultimate Combo with Continuous Generation

By combining it with AutoBatchRunner, you can achieve Automatic Random Update on Every RUN × 100 Batch Generation! → Check the Integration Guide for details!

• ComfyUI's standard batch feature (the number next to the Run button) does not perform random pickup for each image, even if you specify 32 images. → The standard feature only generates 32 consecutive images with the same prompt. To leverage the /C tag's automatic random update, you would need to manually press the "Generate" button 32 times. AutoBatchRunner automates this process with 1 click.

Tag Rules (/C + /R Required)

Add tags to the end of the node title. Spaces, tabs, and newlines are ignored. Compound tags (e.g., /R2a) are invalid → A warning will be displayed.

Tag	Meaning
/a	Exclude from Shift+A
/v	Exclude from Shift+V
/r	Exclude from Shift+R
/R[n]	Select exactly n items from the section
/R[n]-[m]	Randomly select between n and m items
/R-[m]	Randomly select between 0 and m items
/R-N-M	Randomly select between -N and M items (Negative value = 0 selection, N "miss" slots, Total possibilities = N+M+1)
/C	Automatic random update on every RUN (Generate) button press

Example: Pose /R-8-2 /C → Automatically selects between -8 and 2 items every time (0 probability ≈ 72.7%, max=2), applied immediately upon Generate.

Known Bugs

• Starts in edit mode and cannot revert to normal mode no matter what (Confirmed on 2025/11/10 with a large workflow) Please close the ComfyUI browser tab and reopen it (Ctrl+Shift+R or a non-cached reload might be better).
• Stops with an error after long generation times combined with AutoBatchRunner (Fetch error related) (Experienced daily by the author in a paperspace environment) AI suggested that doing it locally or lightening the workflow might prevent the error, but the workflow is still large...

Next Steps Planned

1. Implementation of a mode that generates prompts using a wildcard system for random pickup and runs purely server-side.
2. Implementation of random pickup at the group level, separated by separators (e.g., RG0-2).
3. Pickups other than random (e.g., enabling the next element after 20 images are generated).
4. Since it only outputs text, in combination with the above feature, is it possible to switch models or change the output image size every time?
