Sherlock Calls
for Retell AI + Synthflow
Retell AI handles AI phone conversations from dial to disposition. Synthflow orchestrates no-code voice AI workflows for any use case. When you need to investigate across both, the evidence is split between two dashboards neither of which knows the other exists. Sherlock Calls bridges them — no code, no exports, no manual joins. Ask once from Slack and get a sourced answer in under 5 seconds.
TL;DR — What beta users get access to
- 1
Sherlock Calls connects to Retell AI, Synthflow simultaneously — read-only, no code changes, no webhooks — and lets you query both with a single Slack message.
- 2
Ask questions that neither Retell AI nor Synthflow can answer alone. Retell AI shows conversation results — not the telephony layer that carries them. Synthflow shows workflow metrics — not which calls produce downstream business results. Sherlock deduces the complete picture from both.
- 3
No dashboard switching, no manual joins, no fog of uncertainty — ask in Slack and receive a sourced answer with evidence from every connected provider in under 5 seconds. The game is afoot.

The Investigation Gap
What's invisible when you use Retell AI + Synthflow without Sherlock
Each platform shows you its own data. But the questions that matter most live in the gaps between them.
Retell AI and Synthflow each hold half the picture
Retell AI shows conversation results — not the telephony layer that carries them. Synthflow shows workflow metrics — not which calls produce downstream business results. Without correlating both, your team sees two incomplete views of the same underlying reality — and every investigation stops at the boundary between systems.
Cross-platform cost and performance remain invisible
Retell AI tracks its own agent compute cost. Synthflow tracks its own workflow run cost. Your true cost per outcome — and the performance of each component in your combined stack — requires data from both, but neither platform shows you that unified picture.
Critical events disappear at the boundary between systems
When a session, contact, or signal moves between Retell AI and Synthflow, the transition is recorded with different identifiers in each system. Tracing what happens across the full journey requires a manual join that takes hours you don't have.

FAQ
Common questions about Sherlock + Retell AI + Synthflow
How does Sherlock Calls connect Retell AI and Synthflow data?
- Sherlock uses read-only API access to both platforms simultaneously. When you ask a question, it queries Retell AI, Synthflow in parallel, correlates the results by timestamp and shared identifiers, and produces a single sourced answer — the same way a good detective correlates evidence from multiple witnesses.
Do I need to set up any data pipelines between Retell AI and Synthflow?
- No. Sherlock Calls is entirely pull-based — it queries both APIs on demand when you ask a question. There are no webhooks, no ETL pipelines, no data warehouses, and no code changes required in any of the connected platforms.
What kinds of questions can I ask about my Retell AI + Synthflow stack?
- You can investigate anything that spans both platforms — conversation completion and sentiment rate, workflow completion rate per step, cross-platform costs, handoff patterns, and performance comparisons. Sherlock translates your plain-English question into the right API calls and returns the deduced answer.
Is my Retell AI and Synthflow data stored by Sherlock?
- No. Sherlock Calls queries your data in real time and returns results directly to Slack — nothing is stored, indexed, or replicated in any Sherlock database. All data remains in Retell AI and Synthflow and is accessed only during an active investigation.
How long does it take to set up the Retell AI + Synthflow integration?
- Elementary — typically under 5 minutes total. Connect each platform with read-only credentials, install the Sherlock Calls Slack app, and ask your first question. No engineering, no dashboards, no onboarding calls required.
