Features and specs

What each product offers, as listed by its team.

DeveloperToolStack 5 features
useSherlock.ai 7 features
  • Unified Toolset
    Consolidates multiple developer utilities into a single platform, reducing the need to switch between different tools and websites for common development tasks.
  • Time Efficiency
    Streamlines repetitive tasks like formatting, encoding, and conversions, which can significantly speed up development workflows compared to searching for individual tools.
  • Accessibility
    Being web-based, it can typically be accessed from any device with a browser without requiring installation, making it convenient for quick tasks on the go.
  • Learning Curve
    Having a consistent interface across multiple tools within the same platform can make it easier for developers to learn and navigate compared to using disparate third-party tools.
  • Cost-Effective Option
    May offer a free or affordable alternative to purchasing multiple separate paid tools or subscriptions for different development utilities.

Possible disadvantages

  • Limited Information Availability
    As a specific niche tool, there may be limited independent reviews, documentation, or community feedback available to fully evaluate its reliability and feature set.
  • Potential Feature Limitations
    Aggregator-style platforms often provide simplified versions of tools that may lack the advanced features or customization options found in specialized standalone applications.
  • Dependency on Internet Connection
    Being a web-based service, functionality is likely dependent on having a stable internet connection, unlike offline desktop tools.
  • Data Privacy Concerns
    Using an online tool for code snippets, data formatting, or other developer tasks may raise concerns about how sensitive information or code is handled, stored, or transmitted.
  • Uncertain Long-term Support
    As with many smaller developer tool platforms, there's uncertainty about the longevity of support, updates, and maintenance compared to established, well-funded alternatives.
  • CALL INVESTIGATION
    Ask Sherlock Calls about any call in Slack. Get details, status, duration, events, and errors from Twilio or Genesys in one question — it fetches everything automatically.
  • TRANSCRIPT ANALYSIS
    Search through ElevenLabs conversation transcripts right from Slack. Find specific moments, keywords, or patterns across hundreds of calls instantly.
  • MARKETING & ADS INSIGHTS
    Correlate call outcomes with ad campaigns. Ask "Which Google Ads campaign drove the most qualified calls this week?" and Sherlock Calls cross-references call data with Google Ads, Meta Ads, and Analytics.
  • CRM SYNC & ENRICHMENT
    Sherlock Calls connects to HubSpot, Salesforce, and Dynamics 365 to enrich call data with CRM context. Ask "What deal stage is the caller from +34 611...?" and get the full picture — calls, contacts, and pipeline in one answer.
  • COST BREAKDOWN
    Ask "What did calls cost this week?" in Slack and get an instant breakdown by provider. Spot anomalies, track spending trends, and optimize per-call economics.
  • CROSS-SERVICE CORRELATION
    Sherlock Calls builds a unified timeline across Twilio, ElevenLabs, your CRM, and ad platforms. See the full journey — from ad click to call to deal closed — posted as a clean thread in Slack.
  • MULTI-CHANNEL, MULTI-PROVIDER
    Works in Slack today, with WhatsApp, Telegram, and email coming soon. Connects to voice providers, CRMs, ad platforms, and analytics — each integration is a plugin.

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 DeveloperToolStack 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.
