Sherlock Calls vs Noveum AI
Noveum AI provides real-time observability for production AI agents — with 67+ evaluation scorers, multi-agent trace visualization, and NovaPilot, an AI-powered optimization layer that surfaces recommendations automatically. Sherlock Calls is built for a different layer: voice call operations teams who need to investigate specific calls in plain English from Slack.
TL;DR — The short answer
- 1
Noveum AI is a well-built observability platform for production AI agents — with unusually comprehensive evaluation coverage (67+ scorers) and an AI-powered optimization layer that goes beyond passive monitoring.
- 2
Sherlock Calls is purpose-built for voice operations: investigating specific call failures, pulling transcripts, and correlating costs across 15+ voice providers in Slack — with no SDK required.
- 3
Noveum monitors AI agent quality over time; Sherlock investigates specific voice call events on demand. Different layers, different teams.

Key differences
Why teams switch from Noveum AI to Sherlock
Voice Call Investigation vs AI Agent Quality Monitoring
Sherlock Calls
Sherlock investigates specific production voice calls — failed calls, transcript anomalies, cost spikes, cross-provider failures — on demand from Slack, with answers in under 5 seconds and no engineering involvement.
Noveum AI
Noveum AI monitors AI agent quality over time — scoring hallucinations, tracking cost drift, and surfacing optimization recommendations. It is designed for engineering and MLOps teams improving agent quality, not for ops teams investigating specific voice call events.
Native Voice Provider Coverage vs LLM Framework Coverage
Sherlock Calls
Sherlock natively integrates with 15+ voice and business platforms — Twilio, ElevenLabs, Vapi, Retell, Genesys, Amazon Connect, HubSpot, Datadog — your full voice stack, with no instrumentation required.
Noveum AI
Noveum AI integrates with LangChain, CrewAI, LangGraph, LlamaIndex, and major LLM APIs via SDK. It has no native connectors for voice telephony providers like Twilio, ElevenLabs, or Genesys — integrating voice call data would require custom instrumentation.
Slack-Native Investigation vs Platform Dashboard
Sherlock Calls
Sherlock lives in your Slack workspace — no new tool to learn, no new dashboard, no context switching. Ask a question, get an answer sourced from your actual provider data in under 5 seconds.
Noveum AI
Noveum AI operates through its own web platform with dedicated dashboards for traces, evaluations, and cost analytics. Investigation and monitoring require logging into and navigating the Noveum interface.
Which tool is right for you?
When to choose Sherlock vs Noveum AI
Choose Sherlock Calls if…
- Your voice operations team needs to investigate specific production call failures without an evaluation pipeline
