YPrompt is a self-hosted web application that uses AI-guided conversation to elicit user requirements and automatically generate professional system and user prompts. It includes prompt optimization with effect comparison, version management with rollback, an instant-rendering playground, and experimental multi-turn image generation/editing with image-to-prompt reverse engineering.

Use cases

• generate professional system prompts through AI-guided conversation
• optimize and compare system and user prompts
• manage prompt versions and roll back to history
• test prompts in a playground with instant rendering
• generate and edit images through multi-turn dialogue
• reverse-engineer prompts from uploaded images
• optimize drawing prompts and translate them

When to choose

• you want a self-hosted tool to craft and refine LLM prompts interactively
• you need version control and A/B comparison for prompts
• you want conversational image generation with prompt reverse-engineering in one tool

When to avoid

• you need a commercial product since the CC BY-NC-SA 4.0 license forbids commercial use
• you only need a simple prompt library without AI-assisted generation
• you require permissive licensing for derivative redistribution under different terms
