Statistical Rigor Meets Team Collaboration
The complete platform for teams who need statistically validated prompt optimization and production monitoring.
Validate with Statistical Confidence, Not Guesswork
Run 10-50 trials per experiment and get confidence intervals powered by t-distribution analysis. Know your prompt accuracy with 95% confidence—no data scientist required.
Configurable Trials
Set 10-50 trials per experiment for statistically significant results.
T-Distribution Analysis
Automatic confidence interval calculation with proper statistical methods.
95% Confidence Intervals
Know exactly how reliable your prompt is with statistical proof.
Field-Level Accuracy
See which extraction fields perform well and which need improvement.
Improve Prompts Together as a Team
Role-based access control enables everyone—from engineers to domain experts—to contribute to prompt quality. Share datasets, compare results, and converge on the best prompts.
4 Roles for Every Team
Admin, Experimenter, Prompt Improver, and Data Quality Assurer—each with appropriate permissions.
Shared Datasets
Everyone tests against the same ground truth data. No more "it worked on my test."
Organization Management
SSO integration, team invitations, and centralized billing for enterprise teams.
The Prompt Improvement Cycle
Four stages that continuously strengthen your prompts. Each cycle adds real-world data to your evaluation set, making prompts more robust over time.
Labeling
Efficiently label ground truth with an intuitive UI. Consistent, high-quality labels are the foundation of reliable evaluation.
Data Copy
Add failed or edge-case data back into your evaluation set. Maintain past accuracy while adapting to new data for more robust prompts.
Experiment
Run statistical experiments on quality datasets. Evaluate prompt output with confidence intervals so your team can converge on the best prompt.
Monitoring
Measure how your prompt performs on real user data in production. Detect accuracy regressions before they impact your business.

Built for Production Teams
Multimodal Testing
Test extraction accuracy for images, videos, and PDF documents. One of the few platforms supporting vision LLM testing.
Multi-LLM Comparison
Compare GPT-4, Claude, and Gemini side-by-side. Find the best model for your specific use case.
Enterprise Security
SSO authentication, KMS-encrypted API keys, organization data isolation, and audit-ready logging.
