VITAS centers on a German phone assistant configured through scenarios. SayTrue centers on approved knowledge, explicit outcomes and managed deployment across several channels.
The VITAS column uses telefonassistent.de and VITAS public product, pricing and security pages checked on the date below.
| Dimension | SayTrue | VITAS |
|---|---|---|
| Channels | Phone, a web chat widget, Facebook and Instagram inboxes, and a sales inbox. WhatsApp is not available. | Inbound phone answering is the core product; a website chatbot and a Messenger flow initiated by email or SMS are add-on modules. |
| Conversation basis | Approved knowledge-base entries ground answers and every lookup is logged. | Customers build structured scenarios with fixed questions and answer options, or free scenarios driven by a customer-written prompt. |
| Human follow-up | Working hours control live transfers; structured tickets route unresolved requests to departments. | Direct call transfer is available, while automatic transcripts appear as tickets in the Telefonassistent app for follow-up. |
| Setup | Bytecode guides configuration and a real test call gates go-live. | Customers register and configure the browser-based assistant themselves, then activate it through call forwarding; a consultation is optional. |
| Pricing model | Prices are not published; an engagement starts with a demo and pilot conversation. | Public monthly subscriptions bill per conversation, with included allowances, overage and separately priced feature modules; a non-binding free trial is published. |
| Procurement context | Retention is configured per agent and purged nightly. | VITAS claims Germany-only processing without US third-party providers and lists ISO 27001, BSI C5 Type 1 and external auditing. |
| Market focus | Industry specifics are tenant configuration on one shared platform. | telefonassistent.de targets German practices, medical care centers, clinics and hospitals, with healthcare workflow integrations. |
Approved knowledge as the boundary. The agent answers from approved entries and records the lookup that supported the response.
Three outcome states. Grounded, escalated and no source are explicit operational results, without a generated confidence score.
One managed acceptance test. A real call checks the configured languages, knowledge and handover behavior before go-live.
Grounded in your knowledge, honest about its limits, and handed to your team the moment it should be.
