About PromptJesus
The free prompt engineering platform that transforms your simple prompts into comprehensive system instructions using advanced optimization techniques from leading AI companies.
Our Mission
PromptJesus democratizes advanced prompt engineering by making sophisticated AI optimization techniques accessible to everyone. We believe that effective prompt engineering shouldn't require deep technical expertise or expensive tools.
Our platform bridges the gap between simple user inputs and the complex, structured prompts that unlock the full potential of large language models like GPT-4, Claude, Gemini, and others.
What is PromptJesus?
Prompt Transformation Engine
PromptJesus takes your simple, one-line prompts and transforms them into comprehensive system instructions that follow best practices from OpenAI, Google, Anthropic, and other leading AI companies.
Advanced Optimization
Our platform applies sophisticated prompt engineering techniques including context setting, role definition, output formatting, and performance optimization parameters automatically.
Universal Compatibility
Generated prompts work across all major AI platforms including ChatGPT, Claude, Gemini, Perplexity, and other large language models, ensuring maximum versatility.
Completely Free
PromptJesus is entirely free to use with no hidden costs, registration requirements, or usage limits. We believe advanced prompt engineering should be accessible to everyone.
Core Features
Advanced Configuration Options
Fine-tune your prompt generation with comprehensive settings including temperature control, top-p sampling, repetition penalty, token limits, and model selection between Scout and Maverick variants.
- • Temperature: 0-1 (creativity vs consistency control)
- • Top-P: 0-1 (diversity of response control)
- • Repetition Penalty: 1-2 (prevents repetitive outputs)
- • Token Limits: 100-4096 (output length control)
- • Model Selection: Scout (balanced) vs Maverick (creative)
Smart Output Sizing
Choose from three intelligent output sizes optimized for different use cases:
- • Small (S): 100-300 tokens - Concise, focused prompts for quick tasks
- • Medium (M): 300-800 tokens - Balanced prompts for most applications
- • Large (L): 800-4096 tokens - Comprehensive prompts for complex tasks
