Title: AI customer service: voice and chat assistants, built for you | AI Heroes URL: https://aiheroes.io/en/ai-customer-service Description: A voice or chat assistant that takes over the first line, with a hand-off to a colleague. At Medux, 80% of 4,000 calls a month handled by AI. Start sprint from €8,000. # Every call answered AI Heroes builds a voice or chat assistant that takes over the first line of your customer service, with a colleague behind it for anything difficult or urgent. The first step is a six-day start sprint, from €8,000. Plan a start sprint How to start ## What the assistant does In plain language, outside office hours too, inside your own systems. - Answers and holds conversations · The assistant picks up the phone or answers the chat in plain language, in the evening and at weekends too. - Books and moves appointments · Straight into your own calendar or planning system, without anyone retyping it. - Answers questions from your own knowledge · Opening hours, terms, the status of an appointment: from your own documents and systems. - Hands over with a summary · Difficult or urgent questions go to a colleague, who sees at once what it is about. - Every conversation on record · Calls are transcribed and stored, for quality, review and improvement. ## Which technology We build with speech and language models from several providers, for example Deepgram or ElevenLabs for speech and Mistral for language, and choose what fits each application. You are tied to none of them: a model can be switched without rebuilding. ## How to start: the start sprint In six days there is an assistant for one well-defined kind of question, such as moving appointments or questions about opening hours. We test it on real calls or on recordings of calls with your customers. - 6 days: from question to result - €8,000: fixed price, for every way in - 2 weeks: from the first call to the start After six days you have A working voice or chat assistant for one kind of question, tested on real conversations, and the business case: how many calls, the cost per call and when it pays for itself.

It runs on European infrastructure, makes clear that it is AI and hands you to a person when it does not know. · Read the case ## Included in every build - Business case first · Before we build, you know what it costs, what it returns and when it pays for itself. - Compliance by design · AI Act classification, logging, human oversight and European hosting are part of the design. - Your people can work with it · We train the team that will use the system on the system itself. That also covers Article 4 of the AI Act. - Not tied to one AI vendor · You can switch AI models without rebuilding. Everything comes with documentation. What matters most here: your customers know they are talking to AI, every conversation is recorded and a colleague takes over where needed. [How we work](https://aiheroes.io/en/how-we-work) ## Frequently asked questions ### Do customers notice they are talking to AI? Yes. The AI Act requires it, and in what we build the assistant says so at the start of the call. At Medux, callers rated the AI conversations 7.8 out of 10. ### What happens to questions the AI cannot answer? They go to a colleague, with a summary of the conversation. Your customer does not have to tell the story again. ### Does it work for customers who are not comfortable online? Especially for them. That was the reason at Medux: many customers would rather call than arrange things online. A voice that answers in plain language suits them. ### Does it connect to our planning system or CRM? Yes. The assistant books appointments in your own calendar or system and writes details to your CRM. See [connecting AI to your systems](https://aiheroes.io/en/ai-integration). ### Where are the conversations stored? With a European provider or on your own servers, with a retention period we agree with you. More in [AI and the GDPR](https://aiheroes.io/en/insights/ai-and-gdpr). ### What does it cost per call? That is in the business case of the start sprint, for your call volumes. The start sprint itself costs from €8,000.
