Fully handle customer communication and business processes with AI

What is Zentor App?

Zentor App is a modular AI platform for automating customer communication and business processes. The system receives inquiries via webchat, email, WhatsApp, Telegram, SMS, and telephony (via the Zentor SIP-Voicebot), understands the request, carries out the configured process steps, and — on request — guides the case through to completion, GDPR-compliant, EU-hosted, and optionally on-premises.

The AI chatbot doesn't just answer questions: depending on configuration and connected systems, Zentor App books appointments and reservations, sends confirmations and reminders, processes changes and cancellations, and updates connected systems via n8n workflows. Only complex or explicitly defined exceptions are handed off to your team.

Selected Core Platform Modules

From AI chatbot to omnichannel inbox to n8n automation — a selection of central building blocks from the Zentor App's 18 core modules in total.

All communication channels, united

Omnichannel customer communication means bringing every channel a company uses together in a single platform. Customers reach out in different ways — via webchat on the website, WhatsApp, Telegram, SMS, email, or telephony via the Zentor SIP-Voicebot. Without a central omnichannel inbox, silos form: each channel is handled separately, requests get lost, and response times increase.

With the Zentor App Omnichannel Inbox every incoming message flows into a shared interface. Agents see the full conversation history across channels and reply directly — no switching between tools. The AI chatbot automatically handles standard requests and defined processes; only complex or explicitly defined exceptions are handed off to the team.

Webchat widgets integrate directly into your company website and are instantly visible to visitors. WhatsApp enables personal communication on the smartphone — no app download required. Telegram offers fast messaging for tech-savvy audiences. SMS remains a reliable channel for short status updates and confirmations, even without internet access. Email is well suited to detailed replies, document delivery, and formal inquiries. Telephony via the Zentor SIP-Voicebot enables automated call handling. Zentor App receives messages from all six channels simultaneously — your team sees everything in a single, clear interface.

AI chatbot with knowledge base and handover

Zentor App's AI chatbot answers customer inquiries automatically, around the clock. It is built on the integrated knowledge base: documents, product descriptions, FAQ articles, and support content are structured, indexed, and provided to the AI chatbot as context. The more complete the knowledge base, the more precise and helpful the chatbot's answers. For details on how the RAG-based implementation works, see the chatbot with its own knowledge basepage.

When a request exceeds the AI chatbot's capability or a human contact is requested, the handover function takes over: the AI chatbot with handover seamlessly transfers the conversation to a human agent — including the full conversation context, with no need to repeat the request.

Zentor App also integrates n8n workflows for process automation: incoming customer inquiries can be automatically categorized, routed to the right teams, and transferred to external systems. The combination of AI chatbot, omnichannel customer communication, and n8n automations creates a complete platform for modern customer service.

How Zentor App handles a case from start to finish

Whether webchat, email, WhatsApp, Telegram, SMS, or telephony — every case follows the same structured flow until it is completed or handed off to an employee.

For structured requests, n8n workflows can be set up to retrieve data from external systems, book appointments or reservations, and trigger actions in connected tools — for example inventory levels, appointment slots, or order status. If a case is too complex or explicitly defined as an exception, Zentor hands the conversation off via handover to an available agent — including the complete, cross-channel conversation history.

The result is a seamless interplay of automated process handling and human customer service: shorter response times, less recurring manual work, and more fully resolved cases.

Benefits of centralized omnichannel customer communication

Without a central platform, many companies end up with communication silos: one employee manages WhatsApp, emails run through a separate inbox, webchat requests land in a third tool. Every channel requires its own logins, processes, and overviews. Requests get lost, response times rise, and customers have to explain their issue more than once. That costs time — for customers and teams alike.

The Zentor App Omnichannel Inbox brings every incoming message — regardless of channel — into a single interface. Agents see a customer's full communication history across all channels. Escalations, handoffs, and status changes are transparent to the whole team. Fewer tool switches mean fewer errors, faster response times, and a more consistent customer experience across every touchpoint.

GDPR-compliant & secure

Zentor App runs on servers in the EU. The platform infrastructure stays within the EU legal area; if external AI processing or SMS delivery (Twilio) is active, individual data is transferred to the US based on EU Standard Contractual Clauses (SCCs), unless the on-premises deployment with a local model is used instead. The GDPR-compliant AI chatbot supports privacy by design, audit logging, TLS encryption, and tenant-separated data storage.

For companies with special regulatory requirements, Zentor App offers, on request, an on-premises deployment — the entire platform runs on the company's own infrastructure, with no cloud dependency and full data control. Provisioning is prepared as part of a consultation and is currently being rolled out. Whether EU hosting or on-premises: customer data stays where it belongs.

Zentor App also offers configurable privacy options at the tenant level: retention periods, export functions, and channel-specific data minimization. This lets you align chatbot operation with internal policies and external requirements. For details on the technical GDPR implementation, see the GDPR-compliant AI chatbotpage. Prices and available plans are on the pricing page.

Which businesses is Zentor App a fit for?

Zentor App is a multi-tenant SaaS platform for automated customer communication. It suits companies that receive many customer inquiries across multiple channels every day and want to handle them in a structured way. Typical use cases include customer service teams at mid-sized companies, scaling-focused enterprises and digital agenciesrunning AI chatbot solutions for their own clients.

Zentor App is especially well suited to service providers with high inquiry volumes — for example in IT support, real estate, consulting, or trades. These businesses receive many similar requests every day that can largely be automated with a well-maintained knowledge base. Zentor App helps scale customer communication without growing headcount, while keeping service quality consistent.

Zentor App also offers specialized scenarios for property management, auto repair shops, and online stores: property managers automate recurring tenant inquiries with the chatbot for property management, auto repair shops book appointments and hand off complex cases such as tuning requests via chatbot with handover to the shop foreman (full overview: AI chatbot for auto repair shops), while online retailers let the chatbot for online shops automatically answer product, shipping, and returns questions. Businesses looking to actively win new customers through their own website use the chatbot for lead generation , which proactively engages visitors and captures qualified contact data.

The platform lets you run multiple tenants, each with its own configuration, knowledge base, and branding. Every tenant has its own AI chatbot, its own omnichannel customer communication, and its own n8n automations — fully separated and secure.
