Chatbot Design Systems

Chatbot Design & Conversational AI

Deflection counts the people you stopped. Resolution counts the people you helped. We design, build, and tune assistants against the second number — with the conversation design, escalation paths, and evaluation that make it hold up in production.

What you can rely on

  • Designed against resolution and CSAT, not containment
  • Escalation to a human designed in from the start
  • Live evaluation so quality is visible, not assumed

Why Most Chatbots Disappoint

They were built as a deflection tool, and customers can tell within two messages.

It Optimises for Containment, Not Outcomes

A bot that traps someone in a loop scores well on deflection and terribly on renewal. Measuring the wrong thing produces exactly the experience you are trying to avoid.

It Cannot Do Anything

Answering from a help centre is table stakes. Without authenticated access to order, account, and booking systems it cannot resolve the requests that actually generate contact.

Escalation Is an Afterthought

Handover arrives with no context, so the customer repeats themselves and the agent starts cold. The bot has added a step rather than removed one.

Nobody Can Tell If It Is Any Good

Without transcript review, evaluation sets, and per-intent quality tracking, quality drifts silently and the first signal is a complaint.

Duration
30 days
Price
Fixed, from $24,000
Team
4 specialists

What is included

  • Contact-driver analysis from your real transcripts and ticket data
  • Conversation design: persona, tone, dialogue flows, and failure handling
  • A built and integrated assistant on one channel, connected to one real system
  • Escalation with full context handover to your human team
  • An evaluation harness plus a live dashboard for resolution, escalation, and CSAT

Fixed budget and timeline from day one. If the pilot does not hit the agreed resolution target, we tell you plainly rather than reframing the metric.

Deliverables

What a Conversational Engagement Produces

Design artefacts and running software, not a prompt in a text file.

Contact driver analysis
Your real conversations clustered by intent and volume, with the automation opportunity sized per cluster.
Persona and tone guide
How the assistant speaks, what it refuses, and how it behaves when it does not know — written down and testable.
Dialogue flows
Happy paths, edge cases, disambiguation, repair strategies, and the explicit escalation triggers.
Intent and knowledge model
Taxonomy, retrieval design, source-of-truth mapping, and a content maintenance process your team can run.
Integrations
Authenticated access to the systems needed to actually resolve a request, with permissioning and audit logging.
Safety and guardrails
Scope boundaries, refusal behaviour, PII handling, prompt-injection defences, and rate limiting.
Evaluation harness
A labelled test set, automated scoring, and regression runs so every change is measured before release.
Analytics dashboard
Resolution rate, escalation rate, containment, CSAT, cost per conversation, and per-intent quality.

What We Do

Conversation Design

Persona, dialogue, tone, error recovery, and the writing that makes an assistant usable.

Chatbot Development

Building and integrating the assistant across web, mobile, messaging, and in-product surfaces.

AI Agent Development

Tool-using agents that take real actions, with guardrails and human checkpoints.

Voice Assistants

Telephony and voice interfaces, with latency, barge-in, and speech recognition tuning.

Knowledge and Retrieval

Content structuring, retrieval strategy, and keeping answers correct as sources change.

Chatbot Audit

A structured review of an existing assistant with a prioritised improvement plan.

Migration and Replatforming

Moving off a legacy or vendor-locked bot without losing intents or history.

Evaluation and Tuning

Ongoing transcript review, eval expansion, and iteration against live quality data.

Team Training

Teaching your writers and engineers to own conversation design after we leave.

How a Conversational Build Runs

  1. 01

    Analyse

    Week 1

    Transcript and ticket analysis to find what people actually contact you about, and which of it can be resolved end to end.

  2. 02

    Design

    Weeks 2–3

    Persona, flows, failure handling, and escalation. Reviewed with your support team before a line of code is written.

  3. 03

    Build and Evaluate

    Weeks 3–4

    Integration, guardrails, and the evaluation harness. Quality is a measured number before launch, not after.

  4. 04

    Launch and Tune

    Ongoing

    Staged rollout, live transcript review, and weekly iteration against resolution and satisfaction.

FAQ

Chatbot Design Systems: Your Questions Answered

The things prospective clients ask us most often about this service.

Ask us something else
How Much Does a Chatbot Cost?
A rules-based assistant typically runs $15,000 to $30,000. An AI assistant integrated with live systems is generally $75,000 to $150,000. Complex multi-channel agentic builds start around $150,000. Ongoing tuning and support usually sits around $5,000 a month. Integration depth and the number of channels drive the number far more than the model does.
How Do You Measure Success?
Resolution rate first — the share of conversations that end with the customer's problem actually solved. Then escalation rate with context quality, customer satisfaction on bot-handled conversations, cost per resolved contact, and per-intent quality scores. Deflection alone is a vanity metric and we do not report it in isolation.
Does Generative AI Make Conversation Design Unnecessary?
No. A language model is the engine; conversation design is the steering. Scope, persona, refusal behaviour, disambiguation, repair, and escalation still have to be designed deliberately, and they are what separate an assistant people trust from one they route around.
Will It Hallucinate?
The risk is real and it is managed rather than wished away: retrieval grounded in your own sources, explicit refusal behaviour when confidence is low, scope boundaries enforced outside the prompt, and an evaluation suite that tests for exactly this before every release. High-risk intents are routed to a human by design.
Can It Work in More Than One Language?
Yes. Multilingual support is largely a question of content coverage and evaluation rather than model capability, so we scope it by language pair and test each one separately rather than assuming quality transfers.
What Happens to the Conversation Data?
It stays yours. Transcripts are stored in your infrastructure, retention is configured to your policy, and personal data is redacted before it reaches evaluation sets. Model providers are configured with training disabled.
Do You Work with Platforms We Have Already Bought?
Yes. If you are committed to Voiceflow, Rasa, Botpress, Dialogflow, or Lex we will build on it. If a custom build would serve you better we will say so and show the reasoning, including the cost of both routes.
