AI 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.

How AI product teams are using Voicepanel
Click a use case to see how teams evaluate and improve AI products.
Side-by-side evaluations
Compare model or prompt outputs head-to-head
When two outputs look fine in isolation, pairwise comparison reveals which one people actually prefer—and why. Run A/B evaluations at scale with structured preferences and rich rationales your team can act on.
Collect pairwise preferences across models, prompts, and variants
Capture the “why” behind each choice with voice and written rationales
Spot regressions and winners before changes reach production
Why use Voicepanel for AI evaluations?
