A ComfyUI custom node for building varied prompts across batch image or video generations. Split your prompt into independent sections, fill each with multiple options, and let each section pick one per run — via random, seeded-random, increment, or fixed mode. All chosen pieces are joined into a clean single-line output string ready to wire into any text encoder.

cd ComfyUI/custom_nodes
git clone https://github.com/Alatza/ComfyUI-DynamicPromptComposer
Restart ComfyUI. The node will appear under the prompt category.
Search for Dynamic Prompt Composer in the Manager and install from there.
Add the Dynamic Prompt Composer node to your workflow and connect its prompt output to a text encoder or any STRING input.
Each section represents one independent part of your prompt (subject, style, lighting, mood, etc.). Use the Add Section / Remove Section buttons to manage sections — up to 10 can be active at once.
Within a section, list your options separated by newlines or pipes (|):
a sunny day
a rainy night | a foggy morning
Each section has its own mode:
| Mode | Behavior |
|---|---|
random | Picks one element at true random. Non-reproducible every run — the seed input is ignored. |
random (seed) | Picks one element at random using seed as the RNG seed. Same seed always produces the same pick. |
increment | Cycles through elements in order across runs. Resets at the start of each new batch. |
fixed | Always picks the element at the start index. |
randomvsrandom (seed)— Userandomwhen you want a different result every single run with no way to reproduce it. Userandom (seed)when you want to explore combinations by changing the seed, but need to be able to go back to a specific result — same seed always yields the same prompt.
Used by random mode to seed the RNG. Changing the seed changes which elements are picked. Has no effect on increment or fixed sections.
Shared by fixed mode (which element to pin) and increment mode (which element to begin from at the start of each batch). Defaults to 0.
