Wren Dialog Agent
Meet your new dialog partner
Wren helps you design, build, test, and continuously optimize every agentic dialog experience you deploy.
Adaptive by design
Proactively improve KPIs
Wren adapts your agents every day, so every conversation makes the next one better.
Self-healing
Wren monitors live deployments to catch outages, bugs, or bad updates, and automatically drafts repairs.
Self-improving
Wren analyzes real caller requests to find optimization opportunities that will actively improve your key metrics, like containment and CSAT.
HOW YOU CAN USE WREN
The agent behind your agents
Wren gives everyone on your team the reach of a forward-deployed engineer, grounded in hundreds of millions of real conversations.
Actionable Daily Insights
Delivers daily performance reports and proactive recommendations for improving the customer experience.
Test Fixes Before Going Live
Wren writes a simulation test from the calls that failed, records it failing, applies the fix, then records the same test passing. Both runs stay on the branch. It is an executable test, not a model grading its own work.
Automated Fixes From Real Calls
Spots broken flows, drafts fixes, and simulates tests using real conversation data.
Turn Documents Into Working Agents
Generates flows, prompts, and guardrails directly from your documents or simple text descriptions.
Seamless API Integrations
Maps data fields and wires API calls to handle actions like bookings and ticketing.
Understand Exactly Why Callers Drop Off
Analyzes real conversations to tell you exactly where callers drop off and why.
Every channel, every language, every agent you run
Wren supports your entire ecosystem, no matter how complex.
Multichannel
Provides a unified context across voice, web chat, messaging, email, and in-app experiences so customers never have to repeat themselves.
Multilingual
Actively reviews and supports conversations in 45 live languages.
Multi-agent
Monitors every agent across your entire account simultaneously to ensure consistent quality.
We co-build with you
Wren supports your entire engineering ecosystem, no matter how complex.
Built for mission-critical conversations
Complex service calls
Warranty intake end to end: identity verified, address confirmed, troubleshooting resolved, service request created.
Regulated & high-stakes
Banking identity verification, payments, healthcare intake, and outage lines at peak volume.
Turn-taking-sensitive flows
Reference numbers, spellings, card digits. Turn-taking is a prompt, not a threshold.
Outbound
Navigating phone menus and holds, human vs machine detection, reactivating cold leads with CRM read and write.
Prioritize metrics that matter
Tell Wren to prioritize the metrics you care about most, like CSAT, containment, or booking rates. Wren automatically ranks its recommendations based on what will actively improve those numbers, rather than just reacting to the most recent errors.
Failures that cost you
Catch silent escalations, like a broken integration at 2 AM or a confusing prompt, before they drive up your cost-to-serve.
Revenue leaking quietly
Spot exactly where customers abandon flows or make unnecessary transfers. Wren finds these drop-offs in the call data and automatically drafts fixes to close the gap.
Drift you wouldn't otherwise see
Prevent metrics from slowly degrading as your call mix changes. By analyzing every single conversation, Wren catches performance drift while it is still a minor issue.
Get to know our platform
Wren works alongside the rest of the stack. Here is where to go next.
Platform
Dialog Studio
PolyAI's no-code builder for voice agents and conversational AI, and where Wren lives and works. Design and orchestrate every conversation: flows, tools, and brand voice, from no-code to full code without changing platform.
Latest model
Dialog-RSN-1
The audio-native frontier model behind the conversations Wren builds. It reasons directly over raw call audio and responds in under 300ms in production.
Developers
ADK and APIs
Agents as code. Build and version with the Agent Development Kit, connect tools and data over MCP and REST, and run our models as an API endpoint. Everything Wren does, scriptable.
Frequently asked questions
-
PolyAI Wren is the adaptive coding agent for AI voice agents, working inside Dialog Studio on PolyAI's Agentic Dialog Platform. It builds agents from a description, reviews every production conversation on a schedule, raises what is broken or missing with the calls attached, drafts and tests the fix, and waits for a person to approve it. No code required at any step.
-
Yes. Agent Studio is the former name of Dialog Studio, PolyAI's no-code builder for voice agents and conversational AI. Wren works inside Dialog Studio as the layer that keeps agents improving after go-live.
-
No. Every change stops with a person. You approve it, ask a question, or dismiss it, and taking it live runs through your normal publish process. As Wren builds a track record on your account, you will be able to set a confidence threshold below which the simplest, highest-confidence changes ship on their own. Approval stays the defau
-
Wren reviews the full population of conversations on a schedule rather than a sample, scores what it finds for severity, and raises each issue with the calls attached. That replaces manual QA sampling with continuous, automated quality management across every conversation your agents handle.
-
No. Wren reviews only your own account's conversations. What carries across customers is PolyAI's accumulated build practice, never your data.
-
There is nothing to install. Wren is a capability inside Dialog Studio and works on data the platform already holds: your project configuration, your conversation history, your test suite. No integration to build, no data export, no connector to configure. The first review can run over a window of your real conversations straight away.
