AI Chatbot Development in London
AI chatbot development for London businesses that need answers from your content, human handoff, and web or WhatsApp — not a widget that hallucinates policy.
Useful AI chatbots, not toys
AI chatbots built to deflect the right questions
Website AI chatbots
WhatsApp AI chatbots
RAG knowledge chatbots
Human chatbot handoff
A clear AI chatbot process from use case to live bot
Chatbot jobs & channels
We lock the questions, tone, languages and where the AI chatbot must never answer.
Knowledge & chatbot guardrails
Source content, refusal rules, and evaluation questions before widget polish.
Build the chatbot
Web widget or WhatsApp, CRM/tickets, auth if the bot needs it.
Test with real questions
Staff abuse-test the chatbot. We fix retrieval, not just the greeting.
Launch & tune the bot
Go-live, transcript review, and a content cadence so the chatbot does not rot.
When an AI chatbot is worth it — and when it is not
If you do not have stable answers written down, an AI chatbot will invent them. If you do, a chatbot can take FAQs, routing and after-hours questions without a night shift.Design Dev builds chatbots as products: retrieval, evaluation, handoff and analytics. We will tell you if a better FAQ and form is the honest first step.
- Grounded chatbot answers from your content
- Clear “I don’t know” and staff takeover
- Website and WhatsApp chatbots
- CRM and ticket handoff from chat
- Tone and compliance rules in the bot
- Containment vs escalation measurement
- UK-English chatbot copy and data handling
- Iteration from real chatbot transcripts

A London AI chatbot team that will not ship a hallucinating receptionist
Design Dev builds AI chatbots for operators who have seen demo-quality widgets. Retrieval, refusal and human handoff are the job.If a FAQ and form is better than a chatbot, we will say so. If a chatbot is right, it is evaluated against real questions — not a scripted demo.

Knowledge before the widget
An AI chatbot is only as good as the sources and refusal rules. We start there.
Handoff is part of the chatbot
Transcript into the tool your staff already use. Dead-end chat is a failed bot.
Channels your customers use
Website and WhatsApp chatbots that share knowledge — not two disconnected toys.
Tune after go-live
Failed topics and seasonal FAQs. A chatbot without a content owner rots.
