Systematically Optimize
LLM Prompts.
Manual Prompt Tuning
Does Not Scale.
You are trying to solve a multi-variable optimisation problem by hand. The result is bloated costs and fragile performance.
Inflated Operational Costs
Your LLM bill is spiraling, but you're afraid to switch to a cheaper model because you can't guarantee quality won't drop.
Wasted Developer Time
Engineers spend days manually tweaking prompts—time that could be spent building new, value-driving features for your customers.
Unreliable Applications
Inconsistent or hallucinated outputs from your RAG pipeline are eroding user trust and creating significant business risk.
Visualize the Entire Trade-off Frontier
EigenPrompt introduces the Pareto frontier, a dynamic, real-time 2D visualization of your prompt optimization. Instantly see the trade-offs between cost and correctness, and select the perfect prompt with data-driven confidence.
1. Define Your Goal
Provide your evaluation dataset, your target LLM, and define what 'good' means for your use case.
2. Submit Your Prompt
Input the base prompt that you want to optimize.
3. Launch Optimization
Our engine automatically generates and tests hundreds of prompt variations.
4. Explore the Frontier
Watch the interactive Pareto chart evolve in real-time and explore the trade-offs.
5. Select & Deploy
Click any point on the frontier to inspect the prompt and deploy the optimal one.
Transform Guesswork into Guarantees
EigenPrompt is more than a text editor. It's a systematic optimization engine that gives you the data to make confident decisions, balancing cost and quality like never before.

EigenPrompt is creating a new category—the Prompt Optimization Platform. We are the essential layer for building complex, cost-effective, and reliable AI applications at scale.
Frequently Asked Questions
Everything you need to know about EigenPrompt.
What is a 'Pareto-optimal set' of prompts?
It's a set of prompts where you can't improve one objective (like making it cheaper) without worsening another (like reducing accuracy). Our platform finds this 'frontier' of optimal prompts for you, so you can choose the best trade-off for your specific needs.
How does this differ from tools like LangSmith or PromptLayer?
While tools like LangSmith and PromptLayer are great for prompt *management* and observability, EigenPrompt is built for prompt *optimization*. We don't just track your prompts; we use multi-objective algorithms to automatically find better ones and visualize the cost-quality trade-offs, a capability no other tool provides.
Do I need to provide my own LLM API keys?
Yes, for the initial version. This gives you full control over your accounts and billing with providers like OpenAI, Anthropic, and Google. You simply add your keys, and our platform handles the orchestration.
Who is EigenPrompt for?
EigenPrompt is designed for LLM engineers, agent developers, and technical product managers who are building and scaling AI features. If you're feeling the pain of manual prompt tuning and rising API costs, it's for you.
What is an 'Optimization Run'?
An Optimization Run is our core value metric. It represents one complete, automated process where EigenPrompt takes your initial prompt and generates a full Pareto-optimal set of new prompts, complete with the interactive visualization. One run solves one optimization problem.
Is there a free trial?
Yes! We offer a 7-day free trial that includes 5 free Optimization Run credits. This is enough to experience the full power of the platform and see a tangible ROI on your own use case before subscribing.
