Sherlock Calls investigates failed voice AI calls and posts the findings in Slack: a correlated cross-provider timeline, root cause with evidence, and first checks in triage order โ€” giving voice AI observability to telephony engineers and on-call SREs without new dashboards.

When a Twilio, ElevenLabs, Vapi, Retell AI, Genesys, or Amazon Connect call fails, the evidence is split across providers with misaligned timestamps and call identifiers. Sherlock connects to your stack via OAuth, correlates all events automatically, and posts a structured incident case file in the same Slack thread where the alert fired. Free to start โ€” 100 credits, no credit card. Team plans from $50/month.

Analysis of TranscriptAPI.com

Overall verdict

  • TranscriptAPI.com appears to be a niche developer tool focused on providing programmatic access to YouTube video transcripts/captions via a simple API, which can be a good choice for developers needing reliable transcript extraction without building their own scraping solution.

Why this product is good

  • Offers a straightforward API specifically for retrieving YouTube transcripts, saving development time
  • Likely handles the complexities of dealing with YouTube's caption system and rate limits
  • Provides a dedicated, focused solution rather than a general-purpose scraping tool
  • May include structured data output (timestamps, formatting) useful for downstream applications
  • Could offer better reliability than self-built scrapers that break with YouTube UI changes

Recommended for

  • Developers building applications that need YouTube video transcript data
  • Content analysis or SEO tools that process video captions at scale
  • Researchers or data scientists working with video transcript datasets
  • SaaS products offering video summarization or search features
  • Teams wanting to avoid maintaining custom YouTube scraping infrastructure

Analysis of useSherlock.ai

Overall verdict

  • I don't have verified, up-to-date information about useSherlock.ai (usesherlock.ai) specifically, so I can't confidently confirm whether it's good or not. It may be a newer or niche tool that isn't well-documented in my training data, so I'd recommend checking recent reviews, its official website, and user feedback on platforms like G2, Product Hunt, or Reddit before making a decision.

Why this product is good

  • No verified data available on features, pricing, or performance
  • Cannot confirm legitimacy, security practices, or company reputation
  • Unable to compare it accurately against competitors without firsthand or documented information

Recommended for

  • Users willing to independently research and test the product before committing
  • Early adopters comfortable trying newer or less-documented tools
  • Those who can verify claims directly through the official site, trials, or community reviews

Questions & Answers

As answered by people managing TranscriptAPI.com and useSherlock.ai.

What makes your product unique?

useSherlock.ai's answer:

Sherlock Calls is the only tool that correlates voice AI call events across multiple providers (Twilio, ElevenLabs, Vapi, Retell AI, etc.) into a single incident case file posted in Slack. Most observability tools show dashboards. Sherlock answers specific questions like why did this call fail? The output is a Slack thread with a timestamped cross-provider timeline, root cause with evidence, troubleshooting options, and first checks in triage order, not another screen to monitor.

Why should a person choose your product over its competitors?

useSherlock.ai's answer:

Generic APM tools like Datadog and New Relic were not built for voice AI stacks. They don't understand the relationship between Twilio telephony events and ElevenLabs TTS behavior, or how webhook delivery timing affects call outcomes. Sherlock is purpose-built for cross-provider voice call correlation. Setup is OAuth-only. 60 seconds, no code changes, no agent installation.

How would you describe the primary audience of your product?

useSherlock.ai's answer:

Engineering teams running voice AI in production: telephony engineers, on-call SREs, voice AI operators, and technical founders whose product relies on AI phone agents built on Twilio, Genesys, ElevenLabs, Vapi, or Retell AI, among others.

What's the story behind your product?

useSherlock.ai's answer:

Built by Borja, Jorge and Jose after years working in the voice AI and telephony space. Every call failure investigation followed the same pattern: open the Twilio console, open the ElevenLabs dashboard, pull webhook logs, reconcile timestamps manually, guess at the root cause. Two to three hours per incident. They kept asking why no tool just answered the question. When they looked and found nothing purpose-built for voice AI stacks, they built it themselves.

Which are the primary technologies used for building your product?

useSherlock.ai's answer:

Next.js, TypeScript, Supabase (PostgreSQL), All major LLMs, Slack API, Stripe, Vercel, Resend, Supabase

Who are some of the biggest customers of your product?

useSherlock.ai's answer:

We are our own first clients and we are seeking other like-minded individuals and teams facing the same problems that could try our product and provide us with some feedback.
