Key differences
Why teams switch from InfiniteWatch to Sherlock
Real Investigation vs Synthetic Monitoring
Sherlock Calls
Sherlock investigates your actual production calls by querying your existing providers in real time — transcripts, costs, errors, and timelines on demand, for any call that happened.
InfiniteWatch
InfiniteWatch deploys synthetic test personas to probe call quality proactively — a genuinely powerful QA layer, but separate from investigating specific calls that have already occurred.
Slack-Native Answers vs Separate Platform
Sherlock Calls
Ask Sherlock anything from your existing Slack channel — 'Why did calls from this number keep failing?' — and get a sourced, multi-provider answer in under 5 seconds, without leaving Slack.
InfiniteWatch
InfiniteWatch operates through its own platform interface. Teams need to log in and navigate a separate dashboard to access insights, which adds context-switching to the investigation workflow.
15+ Provider Coverage Out of the Box
Sherlock Calls
Sherlock correlates voice call data across Twilio, ElevenLabs, Vapi, Retell, Genesys, Amazon Connect, HubSpot, Datadog, and 7+ more providers in a single query — no instrumentation required.
InfiniteWatch
InfiniteWatch is a newer platform (founded October 2025) with voice monitoring and session replay as its initial focus. Multi-provider telephony correlation is still developing.

FAQ
Frequently asked questions
What is the difference between Sherlock Calls and InfiniteWatch?
Sherlock Calls investigates real production voice calls — pulling transcripts, costs, and failure details from your existing providers in real time via Slack. InfiniteWatch focuses on proactive monitoring and synthetic testing, deploying AI personas to probe call quality before issues reach customers. They address adjacent problems in the voice operations lifecycle.
Can InfiniteWatch investigate voice calls from ElevenLabs or Vapi?
InfiniteWatch's Voice Agent primarily focuses on call quality testing and monitoring. Sherlock Calls natively integrates with ElevenLabs, Vapi, Retell, Twilio, Genesys, and 10+ more voice providers without any code changes.
Is Sherlock Calls a good InfiniteWatch alternative?
They serve complementary use cases. If you need proactive synthetic testing of your voice AI, InfiniteWatch is compelling. If you need to investigate actual production calls — pull transcripts, analyze costs, and debug failures across multiple providers — Sherlock Calls is purpose-built for that workflow.
How do I migrate from InfiniteWatch to Sherlock Calls?
There is nothing to migrate. Sherlock connects to your existing Twilio, ElevenLabs, or Genesys accounts via API key — no code changes required. You can run both tools side by side: InfiniteWatch for proactive synthetic testing, Sherlock for investigating real production calls.
Does Sherlock Calls replace InfiniteWatch?
Not necessarily. InfiniteWatch and Sherlock Calls solve adjacent problems across the voice operations lifecycle. InfiniteWatch excels at pre-production quality assurance. Sherlock Calls is built for post-production investigation — debugging calls that already happened and correlating live data across your entire provider stack.
