Voice and chat agents grounded in your data, with confidence routing, human escalation, and a full audit trail. Built for insurance, retail, and enterprises where SaaS chatbot platforms hit their integration or compliance ceiling.
The team at Winder.AI are ready to collaborate with you on your AI project. We tailor our AI solutions to meet your unique needs, allowing you to focus on achieving your strategic objectives. Fill out the form below to get started.
Conversational AI services combine retrieval-augmented generation (RAG), large language models, structured tool use, and human escalation into voice and chat workflows grounded in your business systems. Winder.AI builds custom conversational AI for insurance carriers, retailers, and enterprises whose conversations sit on top of regulated workflows, deep system integration, or high-variance data that SaaS chatbot platforms like Ada, Cognigy, and Kore.ai cannot reach without expensive professional services. Every conversation ships with confidence scoring, escalation routing, an evaluation harness, and a replayable audit trail.
2026 update. The interesting buying decision is no longer “rule-based chatbot vs LLM assistant”, it is “buy a conversational AI platform or build a custom assistant on top of your stack”. Platforms win for self-contained flows where the integration surface is small (returns, basic FAQs, common claims triage). Custom wins where the assistant has to read a policy schedule, look up live stock by store, write into your claims management system, or satisfy a regulator’s audit trail. We help on both sides and most of our engagements land on the custom side because integration depth, not conversational flow design, is the constraint.
| Vertical | Conversational workflows we build | Why custom beats SaaS chatbot platforms | Best for |
|---|---|---|---|
| Insurance | FNOL triage, claims status, policy enquiries, broker submission triage | Conduct Duty audit trails, claims system writebacks, and policy-document grounding push SaaS chatbots into expensive professional services | Carriers and MGAs cutting claim cycle time without losing audit posture |
| Retail | Returns and refunds, order status, product discovery, store locator with stock | Order management writebacks, live stock lookup, and brand-voice grounding outgrow templated chatbot flows fast | Mid-market and enterprise retailers consolidating customer service across channels |
| Winder.AI custom conversational AI across both | RAG, tool use, confidence routing, evaluation harness, full audit trail | Built around your systems, your regulators, and your brand voice, not a vendor’s roadmap | Enterprises where SaaS chatbot platforms cannot meet integration depth, brand voice, or audit requirements |
A conversational AI engagement is a scoped workflow against a specific channel and a specific downstream system. We build the assistant, the retrieval layer, the evaluation harness, and the human escalation path together.
Retrieval-augmented generation grounded in your policies, product catalogue, knowledge base, and live systems. The assistant answers from your authoritative content, not from a language model’s training data.
Structured tool use so the assistant can look up an order, read a policy schedule, raise a return, or open a claim inside your existing systems through their APIs. Writebacks are confirmed and auditable.
Rubric tests on every prompt and model change, conversation-level confidence scoring, escalation to human agents with full context, and an immutable audit trail of every reply, tool call, and override.
Conversation design, regulators, and integration depth change by sector. Each of the dedicated pages below covers the workflows, the regulatory frame, and the assistants we build most in that vertical.
Two vertical workflows where SaaS chatbot platforms hit their ceiling and custom assistants pay back fastest.
Conversational AI for insurance covers First Notice of Loss (FNOL) triage, claims status, policy enquiries, and broker submission triage with Financial Conduct Authority (FCA) Conduct Duty audit trails and claims system writebacks.
Conversational AI for retail covers returns and refunds, order status, product discovery, and store locator with live stock lookup across web, mobile, and WhatsApp.
Most conversational AI vendors demonstrate on clean intents and a happy path. We build assistants that handle messy reality: ambiguous user intent, missing data, regulated workflows, and the long tail of escalations that make production hard.
We build RAG-grounded assistants and voice agents on LangGraph, OpenAI, Anthropic, and open-source models. We do not resell a SaaS chatbot platform, so the architecture follows the workflow rather than the licence.
Accuracy, latency, and escalation rate are monitored on a monthly retainer. Prompts, models, and tools improve month over month rather than freezing at handover. Part of our AI workflow automation managed service.
No juniors, no handoffs. Every engagement is delivered by Phil Winder, PhD, with over 12 years building production AI systems for organisations including Google, Microsoft, and Shell.
Conversational AI usually sits alongside agent development and broader LLM work.

Case study
Winder.AI helped Duetto evaluate offline reinforcement learning for dynamic hotel pricing. Over five months, the engagement progressed from behavioural cloning baselines through Implicit Q-Learning experiments on real booking data, revealing where RL outperforms simpler approaches, what data quality prerequisites exist, and how to evaluate pricing agents when ground truth is unavailable.
Case study
Winder.AI helped Apartment List modernize its machine learning operations by unifying data pipelines, automating Kubeflow workflows, and introducing enterprise-grade governance. The outcome: consistent training and inference data, faster deployment cycles, and self-service capabilities that enabled Apartment List’s data science team to scale model delivery with confidence.
Case study
Using digital twin data to build flight traffic simulators and train reinforcement learning AI agents. A leading aerospace business and Winder.AI opened new horizons for dynamic, data-driven scheduling solutions that integrate with our client’s advanced flight planning technology.
Common questions about conversational AI services. If your question is not covered here, book a call and we will answer it directly.
Platforms like Ada, Cognigy, and Kore.ai give you intent libraries, drag-and-drop flows, and pre-built connectors. They work well when your conversations fit common templates (returns, FAQs, basic claims triage). Custom builds win when grounding has to sit on top of your policy administration, claims, or order management system, when regulators expect a specific audit trail, or when the response model needs to read and reason over your documents. We help on both sides of the choice and most engagements end up custom because the binding constraint is integration depth, not conversational flow design.
Three things. First, retrieval-augmented generation (RAG) grounded in your authoritative content so the model answers from your data, not its training set. Second, confidence thresholds and structured outputs that fail to a scripted escalation rather than a hallucinated answer. Third, evaluation harnesses that score conversations against rubric tests on every model or prompt change, so accuracy regressions are caught before deployment.
A scoped audit runs one to two weeks. A single-channel production assistant for one vertical workflow (claims FNOL triage, returns and refunds, store locator with stock check) ships in four to eight weeks. Multi-channel rollouts and deeper system integrations sit on a monthly retainer sized to scope.
Web chat, mobile chat, voice, WhatsApp, SMS, Microsoft Teams, and embedded in-app surfaces. Channel choice follows the workflow. Insurance FNOL works best as voice plus web; retail returns and order status work best as web and WhatsApp.
Confidence-scored routing. Items above your threshold are handled by the assistant end to end. Items below it are handed to a human agent with the conversation transcript, the user’s intent, the assistant’s best guess, and the source documents already attached. Agents validate and resolve rather than start cold.
Almost never. RAG with your authoritative content plus structured prompts outperforms fine-tuning for most conversational use cases and avoids the data-handling overhead. We fine-tune when style consistency, latency, or token cost makes it the right call, and only with explicit data processing agreements.
