Built for every AI team role

From prompt engineers to procurement teams, get the insights you need to make confident AI decisions.

✅ Prompt engineers

Iterate on prompt design, test across models, and compare outputs side-by-side.

✅ Product managers

Validate model suitability before rollouts with measurable quality gates.

✅ Developers

Run regression tests after LLM updates and catch breaking changes.

✅ AI ops teams

Monitor model drift and quality at scale with scheduled evals and alerts.

✅ Procurement / FinOps

Compare accuracy vs latency vs cost to optimize spend without sacrificing quality.

Everything you need to evaluate AI models

1. Prompt Playground
  • • Prompt editor with templating (e.g. {{name}}, {{input}})
  • • Auto-fill example datasets
  • • Real-time preview of final prompt
2. Eval Builder
Add one or more graders:
  • ✅ Exact match
  • 🎯 Regex
  • ✨ LLM-as-judge (OpenAI/Claude scoring)
  • 🔬 Custom Python or JS scoring logic (advanced)
Select models

OpenAI, Anthropic, Gemini, Mistral, Groq, etc.

Run frequency

Manual, hourly, daily

3. Results Dashboard
  • • Heatmap: model × prompt score matrix
  • • Per‑prompt model ranking
  • • Line/bar charts: accuracy vs latency vs cost
  • • Regression highlights: model that got worse (🔥)
  • • Side‑by‑side output viewer (input + output + score)
4. Teams & Projects
  • • Invite collaborators
  • • Shared prompt libraries
  • • Tagging system: “production”, “experiment”, “archive”
5. Notifications & Alerts
  • • “Alert me when model accuracy < X%”
