Find the Perfect Prompt
for Any Model
Shaprompt uses evolutionary search to automatically discover high-performing prompts for any LLM task — so you can stop guessing and start optimizing.
Engineered for
prompt perfection.
Every tool you need to discover, test, and deploy optimal prompts — powered by evolutionary algorithms and rigorous evaluation.
Evolutionary Search
Treat prompt engineering as a genetic algorithm. Prompts mutate, compete, and evolve across generations to maximize your task performance.
Multiple Strategies
Choose from evolutionary, bootstrap few-shot, MIPRO, or grounded proposal optimizers — each tuned for different prompt optimization scenarios.
Real-Time Metrics
Track fitness scores, generation progress, and performance metrics live as your prompts evolve through each optimization cycle.
Dataset Management
Upload, annotate, and manage evaluation datasets. Split into train/test sets with built-in annotation tools for quality control.
Any LLM Provider
Works with OpenAI, Anthropic, Google, and any LiteLLM-compatible model. Use one model to optimize prompts for another.
Evaluation Suite
Built-in BLEU, ROUGE, semantic similarity, and custom metrics. Comprehensive scoring ensures your optimized prompts truly perform.

How it works
From task definition to deployment in four simple steps.
Define Your Task
Describe what your prompt should accomplish and upload evaluation examples. Set your target model and success metrics.
Evolve Prompts
Our optimizer generates, mutates, and recombines prompt candidates across generations — keeping only the fittest survivors.
Track Progress
Watch fitness scores climb in real-time. Compare generations, inspect mutations, and understand what makes prompts perform.
Deploy the Best
Export the top-performing prompt with full lineage tracking. Ready for production with confidence in measured performance.
