How It Works

Master the Art of Prompt Engineering

From structured batch generation to AI-powered refinement and image creation — here's how to get the most out of PromptAnvil.

1. Categories & Descriptors

Organize prompt elements into categories (e.g., "Lighting", "Camera", "Style"). Fill them with weighted descriptors to build your vocabulary.

2. Weighted Randomness

Not all descriptors are equal. Use sliders to control probability — higher weight means more frequent appearance in generated prompts.

3. Logic & Rules

Create smart dependencies: "If Cyberpunk → add Neon Lights, never Rustic." Rules ensure consistency across all generated prompts.

1

Define Your Toolkit & Template

  • Create categories in the Categories panel — each one represents a dimension of your prompt.
  • Fill categories with descriptors (entries): the specific terms that appear in your prompts.
  • Structure your output with the Template editor using placeholders like {lighting_conditions}.

Refine Probabilities & Logic

  • Adjust category weights to control inclusion rate (e.g., "Lighting" at 50% → only half the prompts).
  • Create logic rules: "If {Style} is Cyberpunk → ALWAYS add Neon Lights."
  • Use the Blueprint to visually inspect and create exclude rules from generated prompts.

Generate, Refine & Preview

  • Click Generate to produce 1–100+ unique prompts based on your configuration.
  • Use AI Refinement (Strict or Creative mode) to polish prompts with a 3-agent pipeline.
  • Send any prompt to the Image Generator to visualize it with one of 6 AI models.

FAQ

Frequently Asked Questions

PromptAnvil is an all-in-one AI prompt toolkit for creating structured prompts at scale. It combines categories, weighted descriptors, logic rules, templates, AI refinement, image generation (6 models including FLUX & Imagen 4), config analysis, and cloud sync — all in one platform.
Categories organize your prompt elements (e.g., 'Lighting', 'Camera', 'Style'). Each category contains descriptors — the specific terms to include. Use templates with placeholders like {lighting_conditions} to structure output. Each descriptor can have a weight that controls how often it appears.
Weighted randomness lets you control descriptor frequency. Use sliders to set each descriptor's probability — higher weight means it appears more often. Categories also have weights that determine their inclusion rate in generated prompts.
Logic rules create smart dependencies: 'If Cyberpunk style → ALWAYS add Neon Lights, NEVER add Rustic'. Rules prevent impossible combinations and ensure consistency. You can also auto-create exclude rules from the Blueprint visual breakdown.
AI Config Generator (describe what you want, AI builds it), Quick Generate (one-shot prompt creation), 3-agent Prompt Refinement (Critic → Refiner → Evaluator), Single Prompt Refiner, Config Analyzer, AI Rule Generator, AI Entry Generator, and AI Image Generation with 6 models (FLUX Schnell, FLUX Dev, FLUX Pro Ultra, Recraft V3, Imagen 4, Banana Pro).
Coal is the credit currency for AI-powered features. Non-AI features (batch generation, exports, config management) are always free. Free accounts get 100 Coal with daily refills. Each AI operation has a specific Coal cost displayed before use.
Yes! Sign in with Google to save configurations to the cloud, access prompt history with favorites, and optionally share configs publicly. You can also export/import configs as JSON files for local backup.
Six models via fal.ai: FLUX Schnell (fast, ~3s), FLUX Dev (HD quality), FLUX Pro Ultra (premium), Recraft V3 (creative style), Imagen 4 (Google), and Banana Pro (top tier). Supports 5 aspect ratios and 3 resolution tiers.
