About PromptAnvil
The all-in-one AI prompt toolkit — generate structured prompts at scale, refine them with AI, generate images with 6 models, and build reusable configurations with logic rules, weighted descriptors & templates.
What We Do
PromptAnvil helps creators, dataset engineers, and AI artists design prompts at scale — with intent. Whether you're generating portraits, sci-fi landscapes, or balanced training datasets, you get fine-grained control over structure, diversity, and AI-powered assistance at every step.
Why It Matters
Most prompt tools rely on randomness. PromptAnvil introduces structure: rule-based logic, weight distribution, AI-generated configurations, and a full refinement pipeline — enabling consistent, scalable generation for production use cases.
How to Use PromptAnvil
Five steps to structured, high-quality prompt generation.
Select Categories
Choose the prompt categories you want — portraits, landscapes, characters, or anything custom.
Adjust Descriptors
Fine-tune traits like lighting, era, or emotion using weighted sliders.
Use Prompt Logic
Add conditional rules: "If cyberpunk, always add neon lights but never rustic."
Generate
Click Generate to produce your custom batch — from 1 to 100+ unique prompts instantly.
Refine, Export & Reuse
Polish with AI, export as TXT/JSON, save configs to the cloud for future use.
AI-Powered Features
Every AI feature is optional and runs on the Coal credit system. Non-AI features like batch generation, exports, and config creation are always free.
AI Config Generator
Describe what you want in plain English — AI builds a full configuration with categories, descriptors, templates & logic.
Quick Generate
Skip the setup entirely. Select categories, hit generate, and get AI-powered prompts in one shot.
AI Image Generator
6 state-of-the-art models (FLUX, Imagen 4, Recraft V3 & more) — generate images directly from your prompts.
Config Analyzer
AI reviews your configuration for balance, coverage gaps, and suggests improvements.
