A purpose-built toolkit for teams who need prompt QA they can trust.
Build test datasets with expected outputs. Run them on every prompt change to catch regressions before they ship.
Set pass/fail thresholds for your evals. Block releases that don't meet your quality bar automatically.
See exactly what changed between prompt versions. Visual diffs show where outputs broke and why.
Test the same prompt across OpenAI, Anthropic, and Google side-by-side. Find the best model for your use case.
Generate links for PRs, Slack, or stakeholder reviews. Everyone can see test results without an account.
Bring your own API keys. They're encrypted at rest, never logged, and stay under your control.
Catch regressions specific to your application
Prevent tone and accuracy regressions in customer-facing responses.
Prevent unsafe queries and incorrect tool actions before they execute.
Prevent citation gaps and coverage drops in retrieval-augmented responses.
No complex configuration. No steep learning curve. Just reliable prompt QA.
Start a project and define your test scenarios. Group related prompts, models, and test cases together.
Build your eval set with FAQs, edge cases, and expected outputs. Import from JSON or create directly in the app.
Test each prompt change against your full dataset. Compare outputs side-by-side across models.
Define pass/fail thresholds. Block releases that regress below your quality bar.
Generate shareable links for code reviews. Stakeholders see results without needing an account.
Start free, upgrade when you need more.
