Double_Prompt_Encode

Double Prompt Encode - Splits text into positive/negative conditioning • double_prompt: Multi-line text with positive and negative prompts • Separator: --- or ---- divides positive/negative prompts • Separator can appear anywhere in the text (not restricted to own line) • Everything before separator becomes positive conditioning • Everything after separator becomes negative conditioning • If no separator found, entire text becomes positive (negative empty)

FiveRandomLines

Combines a static global prompt with one randomly selected non-empty line from each of five text inputs. Each input's selection is controlled by the supplied seed and its position. Positive and negative prompt parts are combined separately, with the global prompt prepended or appended according to prepend_mode, and returned as a single double-prompt string.

Prompt_Extender

A ComfyUI node for building double prompts from two text fields. Can also extend existing prompts when connected. Can prepend or append the additions based on the prepend_mode setting. Features: - Supports separator (---, ----, -----) anywhere: own line or mid-text - Output: always clean --- on its own line - Intelligent tag merging: deduplication, comma-separated - Preserves positive/negative separation

Prompt_Library

Prompt Library - File-based prompt management • project: Select prompt file from dropdown • index: Choose prompt project within file (1-999) • randomize_index: When enabled, index is randomly selected File Syntax: - Empty lines separate projects - A separator made of 3 or more hyphens splits positive/negative prompts - The separator may appear anywhere in the text, not only on its own line - ### at line start marks comments/notes (will be ignored) Outputs: - double_prompt - positive_prompt - negative_prompt

Simple_Prompt_Library

Simple Prompt Library – Text field + seed only • Empty lines separate projects (no empty lines inside a project) • Lines starting with ### are project titles/comments → ignored in output • --- or ---- separates positive/negative prompt (can be mid-line) • Positive prompt can be empty → separator at start allowed • No separator → entire text treated as positive prompt • Seed behavior: - -1 → random project (time-based seed), UI remains -1 - 0 or 1 → first project - 1–999 → project index (1-based); if index exceeds count → treat as seed - ≥1000 → always treat as random seed
