Rubric & Prompt Studio
Define "good" once—then scale it across every model and release
Rubrics and prompts are not documentation. They are the operating system for reliable AI. ProofLab Rubric & Prompt Studio designs the task specifications, prompts, and scoring systems that make evaluation repeatable—and make your human data programs consistent, auditable, and measurable.
Design prompts, task specs, and grading rubrics that make GenAI measurable.
Methodology: Our Calibration Methodology
We design evaluation rubrics that produce consistent, reliable scores. Our calibration process ensures high inter-rater agreement and repeatable assessments.
- Rubric design workshops
- Calibration set creation
- Inter-rater agreement analysis
- Continuous refinement
