📦 ComfyUI Prompt Database

A powerful prompt management system for ComfyUI. Store, categorize, search, and combine prompts with full LoRA integration — all from a beautiful built-in web UI.

---

✨ Features

🗂️ Prompt Management (Web UI)

• Categories — organize prompts into named groups
• Create / Edit / Delete prompts with a slide-out drawer
• Search across names, text, and categories
• Drag & Drop — reorder prompts and move them between categories
• Grid & List views — toggle layout with persistent preference
• Sorting — by name (A→Z / Z→A), newest, oldest, category, or custom order
• Export / Import — backup your entire database as JSON; import with Merge (append new, skip duplicates) or Overwrite
• Keyboard shortcuts — Ctrl+N new prompt, / focus search, Esc close

📖 LoRA Integration

• Attach LoRAs to any prompt with custom strength values (supports negative values)
• LoRA auto-discovery — scans your ComfyUI loras folder
• Per-LoRA enable/disable toggle in Apply Lora Stack (inline circle ●)
• Strength adjustment — ◀ ▶ arrows or manual input, range -2.0 to 2.0
• Reset to defaults — restore original prompt-defined LoRA strengths

🔗 Node System

Four nodes that work together:

| Node | Purpose | |------|---------| | Prompt DB Manager | Opens the web UI for managing your database | | Prompt Selector | Pick one prompt from a category → outputs text + LoRA stack | | Prompt Combiner | Connect multiple selectors → combines all prompts into one string + merged LoRA stack | | Apply Lora Stack | Takes a LoRA stack and applies it to model + clip |

📋 Nodes

Prompt DB Manager

Opens the Prompt Database web interface. Add it to your workflow and click the "📂 Open Manager" button.

Prompt Selector

Select a single prompt from a category.

---

Prompt Combiner

Accepts multiple DB_SELECTION inputs (from Prompt Selectors). Each connected input shows a dropdown for selecting a prompt within that category. Combines all selected prompts into one string.

Inputs:

• separator — how to join prompts: , / newline / space / none

Outputs: | Output | Type | Description | |--------|------|-------------| | combined_prompt | STRING | All selected prompts joined by separator | | lora_stack | LORA_STACK | Merged LoRAs from all selected prompts |

Features:

• Inline mute toggle (● circle) — mute individual categories without disconnecting
• ◀ ▶ arrows — cycle through prompts quickly
• Click prompt name — opens dropdown for full selection
• Prompts are combined in input order (selection_1, selection_2, ...)

Apply Lora Stack

Applies a LORA_STACK to model and clip.

Inputs: | Input | Type | Description | |-------|------|-------------| | model | MODEL | Base model | | clip | CLIP | CLIP model | | lora_stack | LORA_STACK | LoRAs to apply |

Outputs: model, clip (with LoRAs applied)

Features:

• Per-LoRA toggle — click the circle (●) to enable/disable individual LoRAs
• Strength control — ◀ ▶ arrows to adjust, supports -2.0 to 2.0 range
• Reset Values button — restores all strengths to prompt defaults
