Key differences
Why teams switch from Balto to Sherlock
Post-Incident AI Investigation vs Live Human Agent Coaching
Sherlock Calls
Sherlock answers 'What went wrong with this AI voice call?' after it happened — pulling cross-provider data to deliver a root cause. Post-incident forensics.
Balto
Balto operates during live human calls — coaching agents in real time. It has no post-call forensics capability and no integrations with AI voice agent platforms.
AI Voice Agent Stack vs Human CCaaS Integration
Sherlock Calls
Sherlock connects to Twilio, ElevenLabs, Vapi, and Retell via API key — the platforms AI voice agents actually run on.
Balto
Balto integrates with human agent CCaaS platforms. It has no concept of AI-generated call events, TTS latency, or cross-provider telephony correlation.

FAQ
Frequently asked questions
What is the difference between Sherlock Calls and Balto?
Balto coaches human agents in real time during live calls. Sherlock Calls investigates AI voice agent failures after they happen — cross-correlating Twilio, ElevenLabs, and Vapi data in Slack. One is real-time human guidance; the other is post-incident AI forensics.
Is Sherlock Calls a Balto alternative?
For AI voice agent failure investigation, yes. For real-time human agent guidance during live calls, Balto is purpose-built and Sherlock does not serve that use case.
How do I migrate from Balto to Sherlock Calls?
No migration needed. Sherlock and Balto are complementary — different call types, different timing.
Does Sherlock Calls replace Balto?
Not for real-time human agent guidance. ⚠️ Phase 2 note: When Sherlock expands to post-call investigation for human calls, the 'what Balto doesn't do' angle — post-call forensics — becomes a direct BOTF positioning.
