Quality evaluations
Scale human judgment for better AI products
Voicepanel helps AI product builders collect structured human evaluations, including ratings, preferences, and rich rationales, so you can ship model and prompt changes with confidence.

01
Prove your AI is getting better
Score every release against the rubrics you actually care about. Quality becomes a number you can track, not a vibe you debate.
02
Judgment with the “why” attached
Binary pass/fail misses the point. Capture rich rationales that show not just where your AI falls short, but how to make it better.
03
Ground truth your LLM judges trust
Build golden sets and calibration benchmarks so LLM-as-judge systems stay aligned with the humans who define quality.

Rubric development
Define what “good” means before you start scoring
Strong evaluations start with clear criteria. Work with human evaluators to draft, stress-test, and refine rubrics—accuracy, helpfulness, tone, safety, and more—so your team agrees on what quality looks like before you score at scale.
Co-create multi-dimensional rubrics with expert evaluators
Iterate criteria until raters agree on what “good” means
Ship scoring guides your team and LLM judges can both trust
Why use Voicepanel for quality evaluations?
