112 scorers, 15 categories
Hallucination, RAG quality, answer correctness, tool use, coherence, safety: assembled from years of studying how language models fail systematically.
Evaluation
NovaEval scores your real traffic with 112 calibrated evaluators across 15 categories: including the market’s only dedicated voice suite: and builds custom scorers from your product requirements.

01: Capabilities
Hallucination, RAG quality, answer correctness, tool use, coherence, safety: assembled from years of studying how language models fail systematically.
36 dedicated voice scorers: mispronunciation, audio breakage, word error rate, talk-ratio, barge-in, dead-air, and full STT / LLM / TTS pipeline latency.
Disagreement-aware judging instead of a single model’s opinion: fewer hallucinated scores, calibrated verdicts.
Hand over your product requirements; instruction-driven scorers with templated placeholders: input_text, output_text, expected_output, retrieved_context, tool_calls: turn them into evaluation criteria, with scorers suggested from the traffic it sees.
ETL jobs convert production traces into living eval datasets, refreshed continuously: your logs become your benchmark.
A 7/10 means the same thing after the model upgrade. Score distributions are monitored so your instrument never drifts silently.
02: The library
Every scorer reports a score and its reasoning, so you can audit the judge: not just trust it.

03: Under the hood
112 calibrated scorers, a dedicated voice suite, template-driven custom criteria, and datasets that build themselves: with reasoning attached to every verdict.
Scorer library
112 calibrated scorers across 15 categories: hallucination, RAG quality, answer correctness, tool use, coherence, safety, bias, format validation, and more: assembled from years of studying how language models fail.
Voice & audio suite
36 dedicated voice scorers: mispronunciation, audio breakage, word error rate (WER), talk-ratio, barge-in, dead-air, and STT / LLM / TTS pipeline latency: signals a transcript never shows.
Panel of judges
A panel of LLM judges with disagreement awareness replaces a single model’s opinion: fewer hallucinated scores, calibrated verdicts you can defend.
Custom scorers
Instruction-driven scorers with templated placeholders: input_text, output_text, expected_output, retrieved_context, tool_calls, and more: turn your product requirements into evaluation criteria.
Scorer output
Every scorer returns a score from 0–10, a passed boolean, free-text reasoning, and structured metadata: so you audit the judge, not just trust the number.
Datasets from traffic
Evaluation datasets are auto-built from production traces via ETL: your real logs become a living benchmark, refreshed continuously.
The loop
Evaluation is the control signal for everything else: NovaGuard enforces these scores in real time, and NovaPilot optimizes against them.
Next step
Production AI agents your customers can trust.
